Hi Arvin ! Great Channel!! I agree with you, Superdeterminism is not testable, however you are making the same assumptions about free will. Just like science can't explain non-living from living matter, science can't explain free will and self-aware consciousness in the human mind. A scientific investigation wouldn't be possible without "free will". Without "free will", our minds ("brains") wouldn't know how to separate true information or usable data from influenced information or false data. The results from all scientific investigations would be corrupted. Although computers can be programmed to separate data, a computer can only process data by following a human programmer's instructions. For example, a computer can't decide on it's own to choose another way to separate data, it wasn't programmed to recognize as true information or usable data, and influence information or false data. Human beings can have unlimited creativity, like a professional master artist painting on a blank canvas (computers are limited by it's program and circuits), because of our unlimited imaginations. A human mind is more than chemical reactions reacting to the environment, or a product of the physical universe (God created us). We all have a mind ("self-aware consciousness") that is uniquely ours (including genetically identical twins). A human mind probably exist at the quantum energy level (quantum vacuum energy state of matter) that supersedes classical physics (the ordering of cause and effect of the observable physical universe). This superseding property is necessary to have free will. It allows human beings (with God's help) to overcome their emotions, biases, other preconceived ideas, and instantaneous temptations. Time is also needed to evaluate all possible choices accurately and completely, before a decision is made. Dr. Ruth Kastner PhD.; philosopher at physics department at New York State University (who believes "free will" is real and obeys the laws of quantum physics. The uncertain nature of people is not explained by randomness. Quantum phyics is not random. The positions of the subatomic particles only appear to be random, because exact measurements aren't possible (only probability measurements) with modern-day instruments. The Quantum Eraser experiment shows that quantum entangled particles, like a photon, can influence each other instantaneously across great distances in a timeless and spaceless quantum vacuum energy state of matter- "Is what really defines reality in this space-time" -PBS Space Time.
Super deterministic ideas, in my humble opinion, will eventually be footnotes in scientific history.. In essence, NOT taken seriously and with a tinge of amusement.. I still like Sabine, though! Good stuff..
@TuxedoMaskMusic The worm simulation you refer to is FAR from fully simulated despite suggestions it is.. It can't lay eggs with the ability to reproduce freely, right? At this point, it seems more like a mannequin or shell than a complete simulation..
Sabina argued in another video that free will doesn't exist baed on her belief in super determinism. I would argue free will is an emergent property that is evidence against super determinism.. A thought experiment... Lets say we had a machine so advanced it could track every particle/wave in the universe perfectly. A scientist and participant are part of an experiment to test it. The machine says to the scientist in one minute I would lift my right arm. And low in behold in one minute I lift my right hand. Case closed. Super determinism wins., Nope. What if we conduct the same exact experiment but the scientist conducting the experiment tells the participant in advance that they will lift their right arm. Whats to stop the subject from lifting their left arm? This suggests to me at least some information is forever hidden from us. And we interprete that as free will. We can't define freewill precisely because of hidden information.
What I think is missing - some analogues to criticism of superdeterminism in other interpretations. Like SD problem with hidden variables is mapped to wave function collapse problem in Copenhagen interpretation, etc.
10:28 Nothing is independent here in the universe everything came from The Big Bang Singularity so of course nothing is independent of the setup! If that is the ultimate conclusion then of course super determinism is real!
17:03 There is no way to verify many worlds either, and it requires postulating additional never-observable Universes exist, whereas SD only requires assuming that conservation laws are valid at all scales and we just cannot grasp all the virtual particle effects at such small scales.
you say " it requires postulating additional never-observable Universes exis" no, the many worlds is a poor name as it is only locally that superpositions exist, not globally.
@@varun7952Cosmologists break conservation laws all the time. They're hypothesing about the big bang so I guess anything goes when inflation is magically able to create matter out of nothing. Quantum mechanics is obviously very different. They can't expect you to believe in them when their theories clearly violate laws of thermodynamics in the here and now. Because unlike the big bang, their theories are expected to be experimentally reproducible.
@@georgerevell5643 no, the many world interpretation expands entanglement and superposition onto the entire universe, so whenever a wave collapses, the entire universe is split
@@HaeikeVraeik NO! If two quantum particles entangle on earth, the state of a particle on the other side of the universe does not instantly split into two versions, one for each of the versions of the particle on earth. That would be stupid if it split the whole universe as it would add non locality back which is half the point of MWI is to restore locality
Why not accept both? "It's not rocket science" is just another way of saying that something is not complicated or not too difficult to understand. In that case, replacing one phrase for the other makes no sense.

Thanks Arvin for your video! It's difficult to find podcasts arguing for both sides, mostly you have only one bell ringing.. and you took it seriously to propperly explain your opposing view, its so refreshing..!
With all the dodgy "science" that vested interests are paying for, it's nice to see true science where ideas are strengthened not by investment, but by conversation. Maybe Sabine can find the funding to formulate a worthwhile superdeterministic theory.....
If she was a man she would be considered a mediocre thinker. But she still made a whole song and dance ( LITERALLY) whining and complaining about "patriarchy". Virtuesignallist misandry isn't good science ...
No. Superdeterminism is hogwash. It is not sufficient to merely state that there are correlations. You have to explain, why and how they lead to uniform results that mimic the quantum theory.
The interesting thing is that the Many Worlds interpretation does not automatically mean free will either. There is no splitting of worlds simply because a person makes a decision. The splitting of worlds occurs only when there there a quantum interaction.
I was presented with a 14-minute video of myself doing something completely different than my 30ish-hour contiguous memory spanning from the night prior through well past the recorded event, a full month after I had spent the full four weeks going through my recall of the whole day..

@@calebbrunson7120that assumes determinists must be morally bankrupt to be able to object to free will. One can object to all sort of nebulous ideas without being accused with moral liability. In essence your argument is an appeal to authority whereas OP's is an observation. He does not stand to benefit from you being emotionally compromised in this debate. If you actually believe he is a determinist you have to concede the fact that he is not obligated to feel shame just because you accuse him of immorality. After all he is not responsible for his actions. Hope I was clear enough. Cheers.
Thanks for explaining this so beautifully. If I interpret this correctly, even if Superdeterminism exists, you can still not predict the outcome of a quantum experiment. To do so, you would have to measure the properties of the measurement device. To do this you need a bigger measurement device. But then you need to measure that device as well. You need yet another device. The story goes on and in the end you need to measure the entire universe, similar as in Bohm's theory. Only an observer from outside the universe has a chance to make exact predictions of quantum experiments within the universe. Now comes the important point: If you cannot make exact predictions within our universe in principle, then the question of whether it is deterministic or not cannot be answered from within our universe. If a quantum measurement shows result X, you cannot tell if it did so because it was predetermined or if it was random. For that you would need to make a prediction first. It is a bit like trying to proof whether the statement "This statement ist false." is true or false.
No determinism is not true because man is capable of comparing his actions to an ideal standard. A rock falling down a hill does not compare actions at all. A rock had no mind.
Valid point. But if the mind is completely controlled by the laws of physics based solely on physical cause and effect, then what's the difference between the mind and the rock, except the fact that the man with the mind is just aware of his actions? If he has no real control or free will, then does awareness make any difference?
@@michaelrose93 Pseudorandom numbers from a computer can meet all the mathematical requirements for randomness but they are still the result of a deterministic process. I think the OP was referring to “real” randomness (if it exists).
@@robertbutsch1802 Isn't the sequence of the pseudorandom numbers based upon the seed value? If you know that value then it's not entirely random. I would think that randomness would imply unpredictability based upon the starting conditions as well.
@@michaelrose93Pseudorandom numbers having a seed just makes them repeatable. If you were given two lists of "random numbers," one from a pseudorandom generator and one from a "true random" source. There is no test you could do to determine which is which. Without already knowing the seed, pseudorandom numbers are indistinguishable from "true randomness" if it exists. For all we know, the randomness of quantum mechanics could actually be pseudorandom and we just don't know what the seed is.
Even if everything is predetermined, the system is so complex that our ability to reconize it as such is impossible at this point. For all practical purposes it is percieved as having choice.
But the social outcomes are important. If we accept we have no free will then we can talk about how to handle things like criminal justice. If the people doing crimes are not at fault, we can focus on restorative justice and behavior modification, not simply punitive punishments.
@@robsquared2 I disagree. Even if our choices are predetermined, the consequences or lack thereof are still used to make our decisions, using your logic nobody can be blamed for anything. The possibility of punishment is pre-emptive behavior modification
@@robsquared2 Your whole argument assumes that people can "decide" to accept not to have free will. Which would only be possible if they have free will...
Great talk, and the following may help Sabina without having to spend a lot of money on a new experiment but rather of implementing two other experiments…for a better understanding of physics in general. Something no one else has thought of… I call it the “Sourlis Implementation”… Combining the double-slit experiment with the photoelectric effect: Normally these are considered separate experimental setups, but merging them by using a metal plate instead of a standard detection screen is an innovative approach. The indirect observation of interference: Rather than directly observing the interference pattern on a screen, you are inferring it from the spatial distribution of the emitted photoelectrons/secondary electrons. This adds an extra layer of complexity. The delicate balance between wave and particle behavior: The ability to switch between observing interference (wave-like behavior) and obtaining "which-slit" information (particle-like behavior) by simply adding the detectors is a quintessential demonstration of the wave-particle duality in quantum mechanics. The potential for new insights: This modified setup may provide additional insights into the fundamental principles governing the behavior of quantum particles and the measurement process. Exploring the interplay between interference, detection, and electron emission could lead to a deeper understanding into the: a) Wavefunction, as with no detectors in place behind the slits because of the wavefunction intensity will lead to higher emissions and thus provide insights or interpretation of the wavefunction by this intentional manipulation. b) It will reinforce superdeterminism and bohemian mechanics. c) The multiverse theory will have to be redefined. d) Potential Insights into Quantum Computing and Information: Understanding the relationship between wavefunction manipulation and quantum phenomena could have implications for the development of quantum technologies, such as quantum computing and quantum communication. And more And this is based on if the observed results match the standard quantum mechanical model, the very fact that we can intentionally control the wavefunction intensity to produce the anticipated outcomes could be seen as evidence supporting the principles of superdeterminism. The 3 scenarios of results are 1. Wavefunction Intensity play a role as this would be according to the standard Quantum Mechanical theory. 2. Wavefunction Intensity did not have an effect on results which would indicate something a miss with special relativity and that quantum mechanics would have to be redefined without its constraints place on it by special relativity. 3. No emission from plate with detectors in behind the slits would indicate a misunderstanding by mainstream physics, and if this was the case i would suggest the next step would be to remove the slits with leaving the detectors and the full implementation of the rest of the dual experiments intact, and if further no emissions my theory which I have would be of some use, and which lead me to suggesting this implementation being looked into. (Note the two fundamental concepts that the speed of light being constant and that of entanglement being a byproduct would remain yet the Doppler effect would have to be revised). Overall, the integration of these two foundational quantum experiments has the potential to provide a more comprehensive picture of the wavefunction and its behavior, as well as shed light on the ongoing debate between deterministic and probabilistic interpretations of quantum mechanics, including the concept of superdeterminism.
The Sourlis Implementation Of the double-slit and photoelectric effect experiments: Apparatus: 1. Monochromatic light source (e.g., LED or low-power laser) with a photon energy just above the work function of the metal plate 2. Double slit apparatus 3. Metal plate (e.g., thin aluminum or copper foil) chosen to have a work function matched to the photon energy 4. Photoelectron detectors (e.g., microchannel plate detectors) placed behind each slit 5. Voltage source to apply a potential difference across the metal plate 6. Ammeter or picoammeter to measure the photoelectric current 7. Collimating optics (e.g., lenses, apertures) to control the beam shape and angle of incidence 8. Mounting hardware to securely hold the components in place 9. Case 2: Using electrons as the source 10. Apparatus: 11. Electron source (e.g., thermionic electron gun) with an energy just above the work function of the metal plate 12. Double slit apparatus 13. Metal plate (e.g., thin aluminum or copper foil) chosen to have a work function matched to the electron energy 14. Electron detectors (e.g., microchannel plate detectors) placed behind each slit 15. Voltage source to apply a potential difference across the metal plate 16. Ammeter or picoammeter to measure the secondary electron current 17. Collimating and focusing optics (e.g., electrostatic or magnetic lenses) to control the electron beam 18. Vacuum chamber to maintain a high-vacuum environment 19. Mounting hardware to securely hold the components in place The key updates are: * Using a monochromatic light source or a low-energy electron source, just above the work function of the metal plate * Choosing the metal plate material to have a work function matched to the photon/electron energy * This ensures the photoelectric effect or secondary electron emission is induced, but without excessive energy that could complicate the experimental observations.
Regarding the multiverse or many worlds interpretation…the standard MWI predicts that the wavefunction should maintain its interference pattern and higher overall intensity, even with the presence of the slit detectors, since the wavefunction does not collapse according to this interpretation. However, the experimental findings show a lower wavefunction intensity when the detectors are in place, which appears to contradict the MWI's predictions. Overall, I believe the MWi can be further developed and combined with other quantum interpretations to provide a more comprehensive understanding of the complex dynamics at play in the combined double slit and photoelectric effect experiment. By exploring the selective amplification or "biasing" of wavefunction branches, as well as the role of decoherence and measurement interactions, the MWI may be able to be reconciled with the experimental observations. But a case could be made for the MWI whereas the other interpretations could not, and, that would be if no difference is made from the wavefunction intensity (meaning no change in emissions)… explained… Experiment result #2… The experiment shows no reduction in wavefunction intensity, even with the presence of detectors. * This would be a surprising result, as it would contradict the established experimental evidence. * If verified, it would lend strong support to the standard MWI and its prediction of the preservation of the full wavefunction and interference pattern. * It could undermine the current understanding of the role of measurement and decoherence in quantum mechanics. * This outcome would likely require a significant rethinking of how we model the interactions between quantum systems, measurement devices, and the environment. • It could lead to a major shift in the theoretical foundations of quantum mechanics, potentially favoring the MWI over other interpretations.
Me: "How common or rare is a belief in super-determinism (or strict determinism) among those with PhDs in physics?" Belief in strict determinism is uncommon among physicists with PhDs, and super-determinism is even less frequent. Here's why: Strict Determinism: Most physicists accept that the universe operates under physical laws, but randomness plays a role at the quantum level. Strict determinism suggests everything is predetermined, which clashes with quantum mechanics. Super-determinism: This is a loophole in Bell's theorem, a famous physics concept. It proposes hidden variables pre-determine everything, including the choices scientists make during experiments. While a technical possibility, it's seen as unlikely due to: Lack of explanatory power: It doesn't explain much beyond the correlations observed in Bell's theorem. Occam's razor: Simpler explanations (like randomness in quantum mechanics) are preferred. However, there are a few physicists who advocate for super-determinism, like Sabine Hossenfelder. But it's a minority view. Love Sabine. But she's such a borderline crank on this issue, Gemini ends up mentioning her (and her alone) by name.
"borderline crank" - something like that might have told Albert Einstein too, when he first time came up with special relativity. Trust in Gemini? Well there are some others out there on the field: Tim Palmer, Sandro Donadi, Emely Adlam, Gerard T´Hooft (Noble winner), Gilles Brassard...
@@Thomas-gk42 Other than Einstein himself knowing he was being a dumbass? Look, nothing is ever proven or disproven in philosophy, including metaphysics. But determinism is about as dead as Last Thursdayism. Have a nice day, crackpot!
Finally a new video explaining the concept of SUPERDETERMINISM! This new paradigm, even if it may be counterintuitive, seems to me more simple and realistic than the other interpretations because it does not postulate new exotic elements. It also has the advantage of being completely in line with the Einsteinian eternalist block universe!
10:33 Prior to the Copenhagen interpretation the idea that the observer is exactly correlated to the observation would be the accepted view given the classical view that all particles have fully determined propagation via laws of physics. Only after the wave function/probability theory was introduced was there now a way to escape from the fully determined Universe.
All what Sabine stands for is that more research on the topic is necessary, and of course she´s right. Standard QM has given up to solve an inconsistency.
To me, super determinism is the only thing that makes sense. It makes the most sense because it maximizes what we don't know while also understanding it all makes sense. There's far more of the universe we can't see than what we can in the universe and there's far more we don't know than what we know. But when we look at how the pieces demonstrably fit together, it all seems rather mechanistic. The wild card in my mind is emergence; things adding up to more than the sum of it's parts. But, generally I find super determinism to match the closest to how I understand reality.
@@pauljohnson570 It is dependent on your definition of "God" If (God does and exist) and (the way you understand the universe precludes his existence) Then, I would assert, either you understanding of the universe is wrong or your understanding of God is wrong. I further assert its more likely that the understanding of God is wrong because the science is testable and allows for a higher density of agreed upon reality, which gives it more value than that which is unprovable and often used in systems of population control. It could be that what the ancients called "God" is just the quantum level of reality as they understood it, or perhaps God exists outside the confines of this universe and sees it as a solid state (whereas inside we perceive time). I don't think it wise to close one's mind to all possibilities that have a potential to be one day proven, despite the fact that they currently cannot be (not to say you are not doing that, just clarifying my approach on the topic.)
just because you cannot measure it, doesnt mean it has not got a specfic value at a point in time (down to the shortest length of time)?, also why does this even have to rely on whether us as humans can or cannot know a particles value?, isnt that a very anthropic (and very arrogant) way of looking at the universe?
You can predict where that isolated particle will go with certainty, depending how you view it. That particle that gets isolated to fire through a slit is never outside of the field that carries it. Like isolating a drop of water in the ocean to look at. It's still in the ocean and will move in accordance with the motion of the waves. This is just energy we don't interact with till we isolate a particle to look at. A particle is a tiny tiny piece of wave, that never is outside of its carrier wave. You know when you fire it, it will appear with complete certainty in one of the normal wave impact zones on the other side of the slit.

Right away I'll say that I prefer Sabine's approach to SD. On that note, I also think it is "better" than Copenhagen and many worlds. In Copenhagen the measurement is equivalent to the "and then a miracle happens" of those science jokes. It's completely mysterious and taken on faith. Similarly, many worlds depends on "just trust me, there are other universes but we can't ever prove it" because the math somehow allows it. Why would any of these two alternatives be better than simply allowing for all causes and correlations to have been fixed since the beginning? The alternative is some kind of acausal motion, not even probabilistic, but without any reference to the past.
It's why the argument that superdeterminism is unfalsifiable doesn't hold up, since it applies just as much to wave function collapse. If there's no mechanism behind it, how can you prove that's what's happening in the first place? How do you undergrid your interpretation without a mechanism that proves your interpretation correct? Of course, if we did know the mechanism of wave function collapse, then it would cease to be probabilistic in the first place and would render the theory deterministic. It seems paradoxical.
People prefer these because they allow for free will in some way. Superdeterminism strips that away and exposes the illusion of free will (although we still tend to act as if we have it, because it is a great psychological tool to survive without a complete existential crisis).
The massive leap in logic to “you don’t have free will!” from an unfalsifiable model involving quantum interactions is just another example of how so much of science is driven by competing politics and worldview. We don’t even know how the brain makes a thought. We do know that decisions are made based on external information and that we experience and exercise free will by any reasonable definition; including the ability to alter our choices on a whim just to demonstrate that we have free will. Rather than free will being preserved by people “afraid” that nothing matters, there seem to be too many nihilists terrified that everything matters.
Thank you for the video, it has been inspiring and very clear ! I guess that conservation of information and reversibility would strongly imply superdeterminism.
We observe the universe in the present moment (wave function collapse) surrounded by the observable therefore, predictable past (general relativity) moving towards the unobserved therefore, probabilistic future (quantum mechanics).
There is a discussion in law theory that we don’t need prisons or other kinds of criminal justice because of super determinism. Some argue that it’s not someone’s fault to be a criminal because the universe had already decided how the person would act.
Yeah that's pure academic stupidity used to justify a particular political view. The bottom line is that even with super determinism at play, you _still_ need to isolate them from society to prevent them from harming others in the future. It's just that now you're destined to do it or not rather than making a choice about it.
It is still their fault, even if they can't control it. The same way you lock up a lion that you know will eat you. The lion eats other animals by its nature. So by locking up a thief, they brain of the thief will remember what it is like to serve time and not commit more crimes. In other words there is a built in behavior that has to be modified , that behavior is what we call the fault. It is a fault because most people think it is very undesirable in society.
Superdeterminism is absolutely my cup of tea. But I also add in an epistemological argument against the Copenhagen-etc.-interpretations, and their perpetuation of the status quo of Western Metaphysics. That's all they serve to do. Instead of taking an epistemically agnostic position, so many physicists rush to defend the last hope for 'free will,' while sacrificing all those who suffer by it to their undeserved fates. Is that fair?
I think you make a good point. Scientists in general do potentially sacrifice good ideas in an effort to save Free Will...because after all, without Free Will, I'm not sure any scientific endeavor has meaning.
@@ArvinAsh I just think the existential dread of some scientists and religious people is a really bad reason to sacrifice the rest of humanity.

Correction: Actually Copenhagen is agnostic and doesn't attempt to state what is or isn't real prior to observation ("collapse"). Its presumed probabilistic nature is likely the single most frequently misstated feature by physicists about it.
Sure, but Bohr et al essentially tried to avoid the elephant in the room, i.e., issue of what is real, leaving it up to us to interpret what "superposition" means.

If he was proven wrong, why are you commenting in a video that is about an alternative to the Copenhagen Interpretation?
Sabine's rebuttal is shockingly bad. She desperately needs to read some Karl Popper if this is her take on falsifiability. The crucial part she's missing is that it isn't simply falsifiability that's desirable in a theory, it's a falsifiable theory *that we have tried to falsify, but failed!* - this crucial distinction is the entire crux of the scientific enterprise. It's a process afterall, not some deductive property. What makes falsifiability valuable is precisely the power that lies in carrying out the falsification attempt. Because once we try to falsify a theory, and fail, then we're closer to being correct than we were before, by definition. Sabine brings up the example of coming up with 20 falsifiable theories, and falsifying them immediately, and concluding falsifiability is overrated, well, duh. Of course when your example is structured that way, it's the conclusion you reach. Look, I can do the same thing with repeatability. "I have come up with 20 different theories to test, and all of them are repeatable - they all fail the tests every time! Look how overrated repeatability is, it's practically worthless!" - is what Sabine would say. Disappointed. But good video from Arvin overall. I never had a clear picture of local hidden variables prior to this video. Though I do feel like there's some explaining to do when it comes to bohmian mechanics, we have countless QM experiments of conditions changing after we've made a measurement, and the particle somehow taking a different path that should be impossible given our prior measurement.
Did you even listen to her or did you just want to make a self presentation? She´s a leading mathematician and thinker and you are megalomaniac enough to explain her Popper, that´s ridiculous.
"The crucial part she's missing is that it isn't simply falsifiability that's desirable in a theory, it's a falsifiable theory that we have tried to falsify, but failed!" I think you should watch her statement again, because she is essentially saying the very same @18:28 : Having a "falsifiable theory" is not enough, because it is easy to come up with one. It is difficult, however, to come up with "good falsifiable theory" (i.e. one we can and have tried to falsify but failed).
@@Thomas-gk42 How is it ridiculous? Most mathematicians are platonists, they've never read a lick of philosophy. I don't expect Sabine to have read much either.

As always Arvin my appreciation, delight and admiration. You are getting better at adding prosody to your narrative. That makes you even cooler amidst this subtle and complex topic! With my "cariño" for you, your fan from Lima, Peru
I‘m a non-determinist. Why would evolution select for big brains with big prefrontal cortexes (that decide which action to take), when anything is anyways already predetermined? And the probabilistic nature of quantum effects? And bells theorem? To me, superdeterminism is at best a concept like a closed system; philosophically interesting, but not realistically existent.
Our free will boils down to being the puppet master who pulls the strings -> Neurons decide when, which muscle to contract. The "free will" is en emergent property of the complex neural network of our brains, that helps animals to optimize their behavior to survive and reproduce in their environment. Compare to ants, a single ant is not that intelligent, but as a colony they can do amazing things.
If superdeteminism is real, couldn't emergence save free will? If everything was determined, though, what implications would it have on philosophical matters like free will or ethical questions? That's what interests me the most.

If everything is determined and there's no free will in the universe, there's no will at all, no "knowledge" or discovery, no justification behind science or the scientific method, no justification for epistemology since your starting point defeats the possibility of you "obtaining" "knowledge". Things would just be, and there would be no oughts, everything would be a mechanistic soup of molecules... which makes it silly to even entertain, how is a soup of meaningless molecules ever gonna know or justify that claim logically. People need to start looking into philosophy of science and leaving physics where needs to be.
weak emergence means the dynamics of a system of a given level become decoupled with the dynamics of the system at a lower level -- you can imagine it as simply when the higher level dynamics are functions of the *average* of the lower dynamics. strong determinism therefore doesn't lose its consistency, rather it loses its relevance, and indeed, while the universe itself may be taken to 'compute' every nuance and detail of its dynamics, each hierarchical layer distinguishing subsystems needs only 'compute' itself.
15:37 "No one knows what those variables are, or where they might be." Wouldn't much of a "hidden" variable otherwise. 15:58 "There's no testable prediction that Superdeterminism makes." In other words, it has exactly the same amount of uniquely testable predictions as any other interpretation. Which is to say, exactly zero.
I agree with everything you said. I want just to add a few things to your second point: (a) There are interpretations (objective collapse theories for example) that differ in their predictions. (b) There are interpretations (Copenhagen) that strictly speaking make no predictions in some cases because "measurement" is not defined. So they differ empirically. (c) Quantum physics is not special in this regard. Classical mechanics has more or less equivalent formulations (Newton, Lagrange, Hamilton) and so does general relativity (EC, teleparallel, ...). But in quantum physics unlike the other cases people view them more as different somehow and argue over them. (d) Even among theories that make the same predictions some are better than others. Because if you want to bound the predictive power the "complexity" (Rademacher-Kolmogorovcomplexity) of the model description is relevant. So even empirically equivalent models are not "equally likely true". One historical example for (d) is heliocentrism and geocentrism with epicycles. You can represent every heliocentric model as a geocentric model with epicycles up to arbitrary precision. But one should be preferred. For quantum physics I'm therefore of the opinion: The Schrödinger equation is all there is. No objective collapse process. No guiding wave. ... That's all not necessary and just makes the theory more complex without a better fit to empirical data. The (deterministic) Schrödinger equation alone predicts an subjective random collapse of the wave function where the Born rule applies. I don't need anything additionally to make this happen or select one outcome objectively for what we observed so far.
@@tofu-munchingCoalition.ofChaos You know a lot more about this than I do. I've just been watching the various interpretation people go round and round and never seem to make any headway one way or the other.
@@interferon4800 Understandable that you have this impression. But there is progress. For example the Ghirardi-Rimini-Weber theory (GRW) is from an experiment in 2020 almost completely ruled out. The same experiment also ruled out the simplest version of the Diósi-Penrose model. And there are further tests for the Diósi-Penrose model (and random gravity). They directly test if the gravitational field is quantum (allows superposition) or stays classical. I really like the Diósi-Penrose model. It has a conceptual reason (Penrose discovered that where Diósi formulated the model first). It's not like other theories because they dislike some aspect (like randomness for no reason). One postulate in general relativity (equivalence principle) contradicts a superposition in the gravitational field and if you want to make this violation undetectable you get the Diósi-Penrose model. That's all about (a) so far. But my main point is about (d): But I also think the discussion in popular science is focused too much on philosophy (philosophical reasons to like one interpretation over another) and experiments (most predict the sane or almost the same anyway). If you discuss the heliocentric and geocentric model with epicycles this way, it will also seem like both are as good as the another. The discussion online is lacking an important part of the scientific process (statistical learning theory - naïvely Ockham's razor). I could also make other points (like some very popular interpretations are not even capable of describing quantum field theory only non-relativistic quantum mechanics). But I leave it at that. btw. I'm not a physicist but a mathematician. And I think that helps me to make sense of the discussions because a mathematical aspect (statistical learning theory - predictive power estimates) is what's ignored and needed.
03:35. Is this the right way to look at it? We view a particle in a wave function. We fire it through a slit but we know where it will land. It is still in a wave so it will land on a high cycle of one of those waves. We observed a particle, but like isolating a water drop in the ocean to look at while ignoring all the other water, we see that single drop was never out of the waves or fields. The wave function does not collapse. The particle acts like a wave because a particle is simply a point interaction in the larger waves function.
Wave functions aren't descriptions of particles. They are descriptions of unmeasured quantum mechanical ensembles. As such they are completely abstract objects. You will never find any trace of a wave function in nature.
@@schmetterling4477 The quantum field is a wave function. All existence, energy and matter, (particles) including us, emerges downstream of that. We ourselves are wave functions with consciousness on top.
@@danielpaulson8838 A quantum field is not a wave function. Not even close. A wave function describes an infinity of possible outcomes. Nature gives you exactly one. You are not even in the right ballpark as far as counting is concerned. You can't tell the difference between one and infinity here.
If there was an inflatron field that condensed while decaying, the rapid oscillation that created all of the subatomic particles would have correlated all particles before the reheating of the universe. It makes no sense to reject "super determinism" when we observe determinism.
About 15 years ago, I came up with the idea that a totally deterministic universe is compatible with, and, in a sense, necessary for free will - the opposite of what you would expect. Model/Analogy #1: the steering wheel of an automobile would be useless unless there was a deterministic affect on the automobile's wheels when turning the steering wheel. Model/Analogy #2: Conway's "Game of Life" has totally deterministic rules. But, I can determine (steer) the outcome of the game by changing the boundary conditions -- I can add or remove "particles" at any time during the simulation. (Remember, the boundary conditions are not part of the deterministic rules, as they say in PDE class.) Analogously, of course, that means that free will is not part of the universe, but interacts with the universe via a suitable "servo" mechanism, analogous to the power steering assist in an automobile, such as a brain. I suppose it also means that there is something akin to another dimension of time outside of the simulation (universe), that is not the same as the dimension of time inside of the simulation (universe). (I could be wrong, but doesn't LQG also need another dimension of time that is not the same as the time "created" within LQG.)

From this exposition Superdeterminism sides with Einstein in his objection to Bohr's 'spooky action at a distance ', and supports his instinctual response that the glove was already right-handed before the box was opened. Very refreshing, I've always been partial to Einstein v Bohr on entanglement.
Given the relative simplicity of Superdeterminism (compared to QM) I'd accept it more than I do the Copenhagen Interpretation. I'm also not bothered with the thought of giving up free will, so it's easier for me to accept Superdeterminism.
Plus, the free will discussion doesn't even have much to do with superdeterminism. Regular determinism already is incompatible with the existance of free will, depending on how one defines the prefix "free" in free will.
Copenhagen's interpretation is basically witchcraft. Instead of the "God of the gaps", it's the "QM of the gaps". And add some Jedi mind bending reality nonsense to the mix. That's not science, that's superstition.

0:47 "Can we calculate with certainty where we would find them? (....) ... the answer is no." (the electrons/photons). But see, what this argument ignores is the fact that we don't know WHY we can't seem to predict it. And to focus on that point: You need to realize the real implication of this fact: that you do not KNOW the REASON for this. So what could be the reason that we do not know why we can't predict it? Lets logically list the possibilities: 1: That there IS no reason. That there is some kind of total randomness "affecting"(or rather strangely that there is NOT anything affecting) the positions of the particles. Therefore super-determinism does not exist because it would exclude such true randomness. 2: There is a logical reason to their new position, we just simply have not been able to observe or detect whatever that reason is. Now lets look at validity and problems of these two possible explanations: 1: To accept this explanation, that there is no reason, would literally require the rejection of reason. It's literally unreasonable! If you believe in this explanation you have to reject reason. 2: All this explanation requires is the realization that we, as of yet, do not know everything and that we do, as of yet, not posses the ability to 100% fully and completely investigate and observe everything. It's HIGHLY likely that there is some forces or effects at play here that we have simply not discovered yet which may account for the seemingly "true" random nature of the particles behavior. We humans are, after all, not godlike beings with the ability to tap into every truth in this universe we live in. It's not just very reasonable to assume that there is still a lot of things we do not understand about the nature of the universe and how it works, we KNOW that, we KNOW that our knowledge is as of yet highly flawed and missing many pieces to solving the full puzzle. But lets just for a moment imagine that true randomness is actually real that the quantum particles can actually behavior in ways that are entirely without any reason. That there are effects where their behavior is completely severed from any kind of reason. Lets try and imagine that if you can: How would you ever prove it? Since it is unreasonable in nature what kind of reason or logic would you ever be able to apply to determine or prove it? None, there'd be none, by definition. You'd never be able to prove true randomness. On the other hand we can't rule out the possibility that the means to actually observe any possible reasons may be out of our reach, possible entirely, which could be an unfortunate, but logical effect of the actual real structure of how the universe works. If this is the case the knowledge of the real reasons will forever be denied. One might argue that this then would be what true randomness is. What's the difference between an effect that appears completely random because you are forever denied the knowledge of the actual reason and then actual true randomness that would truly not have any reason for it to happen? Obviously there would be a difference, but the knowledge of it would be unattainable. So in effect: true randomness would appear to be real to us, indistinguishable in every way from actual true randomness. In conclusion I think opponents of super determinism is in for a rough ride. They certainly have the challenge cut out for them: Need to disprove reason but you can't use reason to do so. At least proponents of super-determinism will always have logic and reason in their toolbox.
For the double split experiment, couldn't the hidden variables be other subatomic particles flowing around the slits influencing the individual photons?

@@litsci4690 No, in the sense of an area/chamber were there is no subatomic particles flowing through it. Hold out your hand, how many neutrinos are flowing through it right now?
Whatever the answer, I doubt we will solve the measurement problem until we find out how quantum mechanics interacts with gravity. Some of the most beautiful proposals solve both the measurement problem and quantum gravity with the same idea (e.g., Penose's objective collapse, ER = EPR, Oppenheim's postquantum theory).

Exactly what I was thinking. Seems like Copenhagen advocates have had 100 years to give an explanation of measurement and they don’t have one. The characteristics of superdeterminism seem much easier to swallow.
@@kas8131 Currently this boils down to either preferring to not have a satisfactory explanation of the measurement process or the hidden variables. I prefer not to choose at all for now...
@@kas8131AIUI superdeterminism requires that particles at the quantum level are correlated with macroscopic objects such as measurement devices. That makes very little sense to me. It's not just that an observer has no choice of what measurement to make, but also that the whole configuration of the device including any human intervention is pre-determined according to the PARTICULAR particle being measured. If it was the particle next door, the settings would have been different. Except of course it was impossible to measure any particle other than the one measured, just as it's impossible that we would NOT have the power to imagine otherwise. And yet that power of imagination and apparent free choice has delivered so much order in our part of the universe. Mulling over what might be, or what might have been, is how thought itself is constituted. In other words total delusion proves to be the basis of enlightenment. Such a setup is so wild, I think it's almost the perfect proof of theism. Except of course that theists typically require God to have given mankind free will.
Superdeterminism is hogwash. It is not sufficient to merely state that there are correlations. You have to explain, why and how they lead to uniform results that mimic the quantum theory.
I like superdeterminism. I think people don't like it because its uncomfortable. The issue of measurement is overlooked too readily, probably because its a very difficult one to reason about. I think it's a hangover from classical physics, but is an assumption which cannot be made at quantum levels. The issue is, fundamentals of physics research is not seen as needed when the calculations work so well, you can just 'shut up and calculate'.
@@gonavygonavy1193 they are non-classical I agree, but I don't see anything that says they're necessarily non-deterministic. Super-determinism is as valid an interpretation as Copenhagen, or many worlds at this point. I prefer it, but as with all the others, we have no way to show which is the best model.
My issue with super determinism is it gives nihilistic atheists the excuse that nothing they do matters. The universe may be deterministic, but it's fundamentally unpredictable as you can't ever know the starting conditions. The universe may be deterministic, but it will never feel any different to having free will.
No it doesn't. Nothing you do does matter in the scheme of the universe, being an intelligent being able to give yourself meaning is what everyone has to do on their own. Nihilism is to take life at a purely logical scientifically dry level and not inject any humanity or emotion into it. Atheism is completely unrelated.

My opinion is, Superdeterminism is the grandchild of the "all-knowing god" in theology. It rejects randomness and describes time as a predetermined emergent block of incidents. While there is still no method that offers a universal, closed-form solution applicable to all scenarios to even three-body problems, considering the whole universe to be strictly emergent without any non-predictable randomness and throwing probability out of the window might be excessively pretentious.
Scientific arguments deserve better than to just be called "might be pretentious". Fundamentally, superdeterminism is about rejecting arguments based on measurement independence and seeing if it can lead you to new predictions. The implications about randomness are secondary and frankly not very interesting.
As it happens, the concept of sin is based on the idea of free will, determinism precludes the concept of free will, which would be a very critical theological problem. "All knowing god" would have to know the starting position, direction of travel, speed, charge, and spin, of every single elemental particle as it condensed from energy early in the expansion of the universe. That could maybe get you to Deism, the universe is god, but that is not what the churches are selling. The most generous description of "free will" is a cone of potential, looks a bit like a gravity well, it expresses the available freedom of motion (change) for a given object or person. The likelyhood that you will significantly change relative velocity or location much in the next 5 milliseconds is pretty low, where you could be any number of locations a year from now. This is greatly constrained by where you were born, who you were born to, and the circumstances that led up to it. Statistically these factors have an overwhelming impact on wealth and wellbeing, yet it isn't an iron clad indicator for any given individual, the uncertainty principle still applies. (hidden variables) What makes us truly unique is our experiences, which are by nature biased, the lack of free will isn't the same as a lack of agency, but you aren't likely to radically change your outlook on the world without some cause for that change. This dialog is far shorter than the internal dialog that created it, so just in the first step of communication there is significant data loss, we don't think and reason in a vacuum, our world view colors how we see information, and that colored information shapes our world.
You’re not thinking like a scientist there. God knowing everything about every elemental particle is only a problem if you commit a category error, and assume that a being couldn’t know such things because you couldn’t. No theologian would assume that, nor even the Bible writers. What do you think it means that God is “past our understanding?” If God was aware of all outcomes upon creation of the universe/the Big Bang, then both humans and God can be in different senses responsible for human actions. Allowing for free will while also knowing all outcomes at conception can reconcile the older theological issue of Calvinism and Arminianism. It’s fascinating stuff, if you aren’t just looking to dunk on churches as if you learned about science from Rick and Morty episodes.
I'm with Sabine on this one, I believe as measurements get more refined, predicable outcomes will increase revealing an underlying super-determinism of the universe. Either way, super exciting stuff.
To me the biggest problem is that people think random, or unpredictable means we have free will but there is no connection between randomness and free will. Are you really free to make a choice if one choice or another was decided by a random event you have no control over in your brain? Not really, you are now just a puppet of random events, not a director so you are being "determined" by randomness... there's just no way out determinism and I think people just need to let go of the whole concept of free will. At least in the tradition meaning of it. No one is telling you what type of coffee you get to drink in the morning. If your "decision" is determined by deterministic events, random events or something we don't know yet forces/events, who cares? You still got the feeling you are the one who made your choice and isn't that's all that matters?
There is no randomness in physics. Randomness would automatically violate energy and momentum conservation. The problem is that non-randomness does NOT automatically mean determinism. It may mean that in a Galilean universe, but in a relativistic universe it doesn't. The 19th century couldn't get past its random/deterministic false dichotomy fallacy because it didn't know about relativity, yet. This is not the 19th century anymore, though... so one could expect people to know better. For some strange reason they don't.
This blew my mind. At first glance and as its presented here Superdeterminism seems to be more intuitively "correct". It feels right. I had previously accepted the Copenhagen interpretation as gospel but never been satisfied by the whole "wave function inexplicably collapses on measurement" stuff.
You had no choice in feeling it's right. Alternatively, it might be the case that the mind, presented with the evidence and conclusions of two different explanations, will naturally choose the more plausible one. The mind isn't determined so to choose--it would be free otherwise to choose if it wished--but finds the choice that more closely follows rational thinking to be preferable.
I think the problem stems from the fact that we’re 4D creatures, part of a 4D block universe, with a perception of 3D objects (with change and motion provided by the unseen 4th dimension), and we have evolved in a manner that allows only ‘seeing’ the past, not the future. So, the future seems mutable and the past immutable… and to us that’s true and real. But from a view outside our virtual 3D reality, looking at 4D space-time, all is not just deterministic, but determined. Could those hidden variables mentioned simply exist as the shape of space-time…as in general relativity’s explanation of gravity?
I was thinking about that! Time perception and free will could be illusions like colors or taste. These concepts might not exist outside of human brain
The question is, whether our universe is a determined shape within this 4D space you speak of, or not. To simplify it by looking at a 2D-creature with the shape of a point that can move and that experiences the z-axis as time: Does the creature look like one continuous line through 3D space, or would we see lines branching into multiple possible positions that could be reached by the creature and the manifestation of the "actual position" at z=currently is found by observing which branch it moves along, as we move up along the z-axis. In that case, the outside observer still wouldn't know what happens in "the future"(higher z-axis points), as the actual shape is "rendering" while we move along the z-axis. If a particle can go left or right, without it making a difference in the energy potential, why must we assume, that a hidden variable must make the decision for it? If it is possible for such a situation to arise, then two branches should be equally likely and only the rendering of the present moment can show, which branch our observation is on. I am not saying, that this is the truth, I am just saying, that it is not clear, that the description as a 4D space would force our experienced reality to be a determined object for an outside observer.
@@getziie So we're just characters playing a role and the jokes on us because we actually believe we can determine our fates. But to a true higher dimensional observer watching us on their TV it would be just as absurd as us thinking a prerecorded shows characters can suddenly to something differently. Man maybe Buddhists have it right, just accept everything that happens because it can't unhappen. Just try adapt as best we can with what we currently understand and know because that's all we can do.
@@JodattisLoeschblatt I see what you’re saying. I was imagining the outside observer as outside of time. As able to see the past, the present, and future as one 4D block (as one might hold a cube in one’s hand). To the observer the block would contain only 4D space. Nothing like time (i.e.: no change, no motion). And, in that way, the probability is entirely a perception (or conception) of the creature (us) from within that 4D block. So, yes, you’re right… it comes down to whether there exists a ‘View’ from the outside from which space and time are fixed and immutable. I suppose that’s really what determines the question of determinism.
Thank you for the great video. It was a pleasant surprise to see Sabine commenting here. SD sounds like a discussion of, if there is a God with the entire knowledge of the universe, is he able to predict everything or is he subject to the same probabilistic universe? That's pretty much a philosophical discussion, rather than a scientific one. I believe the most important part of the discussion is, in your own words, "You can make any non-deterministic theory a deterministic one by introducing hidden variables." I think SD will just be a philosophical interpretation seeking the comfort of getting rid of the "spooky action at a distance" and in my opinion, this search for comfort is indeed a side effect of our fear of a non-deterministic universe. Correct me if I'm wrong, but some argue that weather events are also non-deterministic and inherently unpredictable. Similarly, one could counter-argue that there is actually superdeterminism at play, governed by hidden variables that no one is aware of yet. That doesn’t change anything except for providing the comfort and belief that we are not completely helpless in explaining and predicting the weather. Besides, not only the quantum events but any ordinary life event, such as whether I will be the first person on Jupiter, is quite unpredictable. I can still argue that the universe was aligned at the Big Bang in such a way that will make me the first one landing on Jupiter . It is unfalsifiable, yet such a discussion would just be a waste of time until I come up with some of those variables
While I agree with you on your objection of treating superdeterminism as a scientific theory vs. a philosophical one, there is a big error in the argument on weather events. Weather events are governed by nonlinear dynamics that is characterized by chaos, which is fully deterministic but not predictable.
Most interpretations of quantum mechanics seem to be fantasies. Copenhagen, many worlds, many histories, super determinism, ghost branches, etc., etc. Pilot waves seem to make the most sense, but they have all kinds of problems too.
Yep. I don't think Bohmian mechanics makes much sense. The biggest problem I have with it is the idea of a "guiding wave" that somehow pushes a particle around without itself being affected, and how variables can be hidden all over the universe but communicate instantly with a given particle.
@@ArvinAsh A great video! It seems that Bohemian Pilot-Wave Theory as is usually portrayed in videos that compare it to other interpretations is rather problematic and dated. I wish that “someone” would do a video on more modern variants on this “theme” that have a historical connection to Bohemian Mechanics but are inspired by more modern “Hydrodynamic Quantum Analogs” that are talked about at the “International Conference on Advances in PilotWave Theory & HQA” and other places. Love the Yves Couder and John Bush research for inspiration. Tho it seems that the “pilot-wave” is going to require some sort of “new field” that will be a huge departure in thinking.
@@ArvinAsh "The biggest problem I have with it is the idea of ... how variables can be hidden all over the universe but communicate instantly with a given particle." Your problem goes away by choosing the labels for the hidden variables appropriately. If you choose the initial positions of the particles as hidden variables, the hidden variables would essentially be a part of the defining inital conditions. Initial conditions don't change and hence don't communicate. They are just inital conditions and thus fixed. Apart from that: I really liked your video. It gave a very good explanation of the subtle differences between determinism and superdeterminism that made it easy to follow for me. Thanks.
I would like to see discussions around a pilot wave model where the non-locality between entangled particles is minimized to their last localized interaction so as to preserve the property of locality as much as possible, but still have the non-local behavior we observe between locally prepared entangled particles we see in experiments. Maybe there is something wrong with this approach, but I think it is the simplest and keeps with the intuition that the universe is for all practical purposes local.

non-local hidden variables violate locality, which is backed by special relativity. What scientific theory backs objective reality? Nothing. Only philosophical ones like marxist materialism
In my opinion we have no free will, however we have the illusion of free will. That's the saving grace, that it seems as though we are making choices ourselves, although all be do can be directly traced back to the beginning of time at the big bang. Our "choices" were determined then.
You and Sabine having a cup of tea is my cup of tea! On topic: the outlandishness of many worlds and wave collapse theories seem about equivalent to pilot wave theory and the superdeterminism property. Is there a measure for outlandishness?
For me the measure is the degree of magic vs. objectivity. SD has no magic in it, it´s just a property of the universe, we can observe. Believing in stuff like collapse of the wave function by observing it is like riding the unicorn.
Many things seem random until you find the pattern that connects them. In due time we will come to the understanding that the universe is superdeterministic.
I honestly kind of wonder if superdeterminism will escape disprovability by simply being subject to Gödel's Incompleteness. Hidden variables might exist outside of the system they have an effect in (i.e. outside the universe as we can perceive it) and therefore only be subject to formal proof if we could escape our own universe. We might just be forced to accept their existence as an axiomatic fact once all other alternatives have been exhausted and leave it at that.
We observe the universe in the present moment (wave function collapse) surrounded by the observable therefore, predictable past (general relativity) moving towards the unobserved therefore, probabilistic future (quantum mechanics).
@@binbots yes i agree. even if we came up with a set of equations to simulate our own universe, we'd have to run the simulation to find out, and we could never do so completely -- for many reasons, namely we'd forever lack the sufficient resources, and also because we'd have to simulate ourselves simulating ourselves, which would require the simulation to know how it will run before it finishes running, which it cannot do lol.
At 11:52, the quote from Bell is confusing. He seems to separate himsel from nature. If you are a determinst, then your 'belief' that you are free to choose to do one experiment rather than another is in fact *just* a belief. Regular determinism means that "the boundary conditiosn of the unvierse" already predetermine what experiments and decisions and measurements you'll do in the year 2024. So why is this called superdeterminism, when it is just regular determinism? Is it just that the corrleations are *relevant* to the experiment enough to impact the result?
All of this is a result of physicists confusing determinism and predictability, as if they're the same thing. They are not. The universe can be deterministic and have non-predictable pockets at the same time. Wolfram refers to these as as "pockets of irreducibility", and he refers to the universe as computationally irreducable. It's a much clearer way to think about all of this. Pretending that the local environment is not influenced by the environment around it, as if it's somehow magically disconnected and you can magically isolate objects, is absurd and it's surprising this ever became de-facto. Everything is influenced by everything, and it goes back to the Big Bang. We will never know these starting conditions. Any model that is not superdeterministic is suffering from the same loopholes and obvious logical contradiction as any model that allows for isolation of objects as if they are not in a universally sized environment. The observers are included in that environment, and their behavior is deterministic as well. The whole notion of "hidden variables" is also subtly misleading. We're viewing all of this incorrectly because of the choices of terrible terminologies physicists have given us, which has the unfortunate side effect of forcing people to look at reality through a particular constrained lens. Kind of like "dark" "matter". Physicists are notoriously bad at naming things. If you want to think about all of this clearly, think about it in terms of computation and cellular automata. Look into Wolfram's work. Or if you'd prefer to hear it from a physics Nobel prize winner because you have an appeal to authority bias, look into Gerard 't Hoofts "Cellular automaton interpretation of quantum mechanics". There are no "hidden variables", there is simply the state of the universe at each time step. There are rules that govern the evolution of the universe, and these rules are the initial starting conditions. That's all you need. This still results in unpredictable and irreducible behavior. It still results in pockets of predictability. It still results in superdeterminism. Anyway, physicists will never embrace this because, as mentioned in the video, they have a religious issue with the notion of "lack of free will". But the issue is they aren't even viewing free will correctly to begin with. If we live in a computationally irreducible universe, it doesn't matter if we technically don't have free will, because the universe is non-predictable. So for all intents and purposes, we can consider ourselves to have it, with no issue. Further to that, for them to embrace this idea would give them far less b.s. to sell to the public. Their industry requires complicated scifi mumbo-jumbo to keep the wheels spinning, to sell books to the masses that don't know any better, and continue to dripfeed investors. Kind of like how the billion dollar cancer industry would completely crush itself if it developed a cure for cancer tomorrow. No surprises that we still don't have that yet either.

Superderminism is real thing. And very simple to explain if you know about two things. Cellular automaton theory and computability. Simply put, in very simplified explanation, to be able to predict next state of the universe, thus of any particular part of the universe, you would need a machine with say "memory capacity" of size of number of all elements in the universe. Intentionaly using word elements rather than particles, as we currently don't know what are the building blocks or smaller elements are. But this is not in collision with what been said. Thus even every moment or future state of the universe is perfectly predetermined, it is not computable due obvious physical limitations. We simply cannot build a machine of the size of our universe within our universe. Righ?

"Entropy is a measure or randomness" -- Roger Penrose. Syntropy is a measure of order -- certainty. Super determinism is dual to super non determinism. Making predictions is a syntropic process -- teleological. Teleological physics (syntropy) is dual to non teleological physics (entropy) -- physics is dual. Information is dual. Average information (entropy) is dual to mutual or co-information (syntropy). Sine is dual to cosine or dual sine -- the word co means mutual and implies duality! Mutual or co-information is used to make predictions -- syntropic! Concepts are dual to percepts -- the mind duality of Immanuel Kant. "Always two there are" -- Yoda. Super determinism implies absolute, objective prediction or complete certainty. "Only the Sith think in terms of absolutes" -- Obi Wan Kenobi. Repetition (patterns) is dual to variation (randomness) -- music is dual.
Precisely, and this is where the "determinism doesn't allow for free will" argument breaks down. We feel as though we have free will because we can't predict our own actions, not because the universe isn't deterministic.
For determinism to be true, all you have to agree is that every effect has to have a cause, hidden or not. Otherwise, explain how an effect can happen without a cause (magic?).
@@bnielsen56 Determinism is not mere causality. Determinism requires us to predict the future based on the present. That is not possible in a relativistic universe. Technically we can't even know the present perfectly because it is entangled with the future. ;-)
@@schmetterling4477 That's because you think time exists, which it clearly does not. 'Time' is a consequence of interaction; no interaction, no time, so no future. Since an interaction 'in the future' has not yet occurred, there's no future to entangle the present. This is why thermodynamics works and why you can't go back in time (no 'negative interactions'). All equations which have an absolute time parameter 't' are wrong. You can think of time in mechanics like acceleration. It's easy to see that acceleration doesn't exist without an interaction and disappears the moment the interaction is removed. Once you get that concept, you still have to explain how you get an effect without cause before entering your own interpretation of determinism.
@@bnielsen56 Time is that which the clocks show. We try to teach this to our kindergarteners, but most of them aren't paying any attention. So what were you so busy with that you weren't paying any attention in K-12? ;-)
If super determinism is true, it still does not eliminate the possibility of free will. If free will exists it must come from something outside the known physical universe. And the initial conditions of a super deterministic universe still come from an unknown source. Therefor it may be that quantum retro causality carries our freewill choices all the way back to the initial conditions in order to fine tune those conditions such that the choice you want to make at this time is made. It may also be that time is simply irrelevant in the realm where free will choices are made. In other words, our free will choices may be the source of the initial conditions of the universe.
I also think that consciousness is not algorithmizable and therefore cannot be deterministic. Moreover, a hypothesis that is by definition unconfirmable and at the same time irrefutable is absolutely worthless.
Obviously an avid fan of that youtube channel that seems to have an interview every other day on this exact topic. It gets too far from “science” to be … Also Penrose’s “retro-activity” seems to have something to say about this topic.

The most important local hidden variable is time. In Newton's framework, timekeeping is the same everywhere. But in Einstein's framework, timekeeping is local, and varies with the strength of the local gravitational field. For a state variable that is time-varying, the phase of the state variable at any given distance, x, depends on whether the distance x is known to within a fraction of the wavelength of the state variable. For photons of visible light, that requires knowing x to within a few angstroms. Were Bell test experiments done with microwaves, one would only need to know x to within a millimeter or so to be able to reckon the phase at distance x. If you don't know the phase at x, then the best model is that it's random. If you can reckon the phase, you have the prospect of determining how a microwave photon might refract at the edge of a grating. Bell adopted the simplifying assumption that spacetime can be modeled as Newtonian, which makes his derivation easy. Had Bell admitted Einstein's model of spacetime, he would have been obliged to employ a gravitational path integral and his state variable would not have vanished, but would have yielded some kind of non-vanishing "beat frequency" term. We know that qubits tend to decohere with distance, and one ineluctable cause of such decoherence is the presence of gravitational gradients in the cosmos, which destroys the possibility of perfect phase-locked synchrony of qubits separated in space. Mathematically speaking, it means we cannot blithely assume λ(x,t) ≡ -λ(-x,t) because the age, t, of the qubits at ±x cannot be assumed to be exactly the same. Since λ(•) cannot be assumed to be an odd function, we cannot claim that it vanishes from the integral that Bell employs in his classical (Newtonian) derivation.
Superdeterminism (SD) is just another way of refuting true randomness. It is similar to information technology (IT), where computers cannot create true randomness with pure computer technologies spontaneously. You can make random generation complex, but it will always result in a pseudo-random procedure. SD is a real-world analogue of pseudo-randomness. If you make pseudo-random generation increasingly complex, it will become more difficult to distinguish from true randomness. However, with enough effort, you can always prove it to be fake. The real-world complexity of randomness makes it too difficult to prove as pseudo.
Doesn't superdeterminism somewhat kill the science? Since if there's no operational independence then how do we know we really even ask the right questions / do right experiements to begin with because the questions we ask are predetermined?
Thanks for this wonderful video! When I was a graduate student, long ago, I tried to solve the measurement problem, not knowing that the correct answer (decoherence) was being developed elsewhere. That led to the many worlds interpretation, in which all possible futures exist somewhere in some pattern of the wave function. The common interpretation of that interpretation is that therefore the world is deterministic because if every pattern of waves in the wave function keeps on rolling on, and we are unaware of them solely because "our" wave pattern no longer interferes with the others, then there is a "them" equally unaware of "us" in their wave pattern. If every outcome happens "somewhere", then the only thing we can say about ourselves is that we are the version of "us" that just happens to be in this particular part of the wave function. Ergo, no free will. I came to the conclusion that there is a mistake - not in the theory, but in the way of looking at it - that not only rescues free will but makes it, if anything, more likely than determinism, even if one accepts every assumption behind many worlds. It is a long story to explain, but I am close to completing two novels (yes, novels!) that explain why. Hopefully the first will be out before the end of the year, so if you are interested, look for "For Selenya" and its sequel, "For Katenya" Now your excellent video has given us a neat summary by Sabine (clearer than her longer versions, imho) of superdeterminism. And it became clear that the same oversight is happening here. IOW, even if all the assumptions behind superdeterminism are correct, it still doesn't say anything about whether free will exists. I'll now have to bung that in somewhere! :-) Very best wishes for your future research! Cheers Ron House.
"...it still doesn't say anything about whether free will exists." - exactly 💯! That's what all those half-intelligent philosophy-guys don't get, and it's what Sabine constantly explained a hundred times. U admire her patience.

Hi Arvin ! Great Channel!!
I agree with you, Superdeterminism is not testable, however you are making the same assumptions about free will.
Just like science can't explain non-living from living matter, science can't explain free will and self-aware consciousness in the human mind.
A scientific investigation wouldn't be possible without "free will". Without "free will", our minds ("brains") wouldn't know how to separate true information or usable data from influenced information or false data. The results from all scientific investigations would be corrupted. Although computers can be programmed to separate data, a computer can only process data by following a human programmer's instructions. For example, a computer can't decide on it's own to choose another way to separate data, it wasn't programmed to recognize as true information or usable data, and influence information or false data. Human beings can have unlimited creativity, like a professional master artist painting on a blank canvas (computers are limited by it's program and circuits), because of our unlimited imaginations.
A human mind is more than chemical reactions reacting to the environment, or a product of the physical universe (God created us). We all have a mind ("self-aware consciousness") that is uniquely ours (including genetically identical twins). A human mind probably exist at the quantum energy level (quantum vacuum energy state of matter) that supersedes classical physics (the ordering of cause and effect of the observable physical universe). This superseding property is necessary to have free will. It allows human beings (with God's help) to overcome their emotions, biases, other preconceived ideas, and instantaneous temptations.
Time is also needed to evaluate all possible choices accurately and completely, before a decision is made. Dr. Ruth Kastner PhD.; philosopher at physics department at New York State University (who believes "free will" is real and obeys the laws of quantum physics.
The uncertain nature of people is not explained by randomness. Quantum phyics is not random. The positions of the subatomic particles only appear to be random, because exact measurements aren't possible (only probability measurements) with modern-day instruments.
The Quantum Eraser experiment shows that quantum entangled particles, like a photon, can influence each other instantaneously across great distances in a timeless and spaceless quantum vacuum energy state of matter- "Is what really defines reality in this space-time" -PBS Space Time.
Super deterministic ideas, in my humble opinion, will eventually be footnotes in scientific history.. In essence, NOT taken seriously and with a tinge of amusement.. I still like Sabine, though! Good stuff..
*SOMEBODY PEER REVIEW MY UNIFIED LAGRANGIAN*
@TuxedoMaskMusic The worm simulation you refer to is FAR from fully simulated despite suggestions it is.. It can't lay eggs with the ability to reproduce freely, right? At this point, it seems more like a mannequin or shell than a complete simulation..
Sabina argued in another video that free will doesn't exist baed on her belief in super determinism. I would argue free will is an emergent property that is evidence against super determinism.. A thought experiment...
Lets say we had a machine so advanced it could track every particle/wave in the universe perfectly. A scientist and participant are part of an experiment to test it. The machine says to the scientist in one minute I would lift my right arm. And low in behold in one minute I lift my right hand. Case closed. Super determinism wins.,
Nope. What if we conduct the same exact experiment but the scientist conducting the experiment tells the participant in advance that they will lift their right arm. Whats to stop the subject from lifting their left arm? This suggests to me at least some information is forever hidden from us. And we interprete that as free will. We can't define freewill precisely because of hidden information.
Thanks, Arvin, for this wonderful video!
What I think is missing - some analogues to criticism of superdeterminism in other interpretations. Like SD problem with hidden variables is mapped to wave function collapse problem in Copenhagen interpretation, etc.
Master Sabine! Much love from Brazil! 😍

17:03 There is no way to verify many worlds either, and it requires postulating additional never-observable Universes exist, whereas SD only requires assuming that conservation laws are valid at all scales and we just cannot grasp all the virtual particle effects at such small scales.

@@varun7952Cosmologists break conservation laws all the time. They're hypothesing about the big bang so I guess anything goes when inflation is magically able to create matter out of nothing. Quantum mechanics is obviously very different. They can't expect you to believe in them when their theories clearly violate laws of thermodynamics in the here and now. Because unlike the big bang, their theories are expected to be experimentally reproducible.
@@georgerevell5643 no, the many world interpretation expands entanglement and superposition onto the entire universe, so whenever a wave collapses, the entire universe is split
@@HaeikeVraeik NO! If two quantum particles entangle on earth, the state of a particle on the other side of the universe does not instantly split into two versions, one for each of the versions of the particle on earth. That would be stupid if it split the whole universe as it would add non locality back which is half the point of MWI is to restore locality
We need to have a vote to replace the phrase "It's not rocket science!" with "It's not quantum physics!"
Why not accept both? "It's not rocket science" is just another way of saying that something is not complicated or not too difficult to understand. In that case, replacing one phrase for the other makes no sense.

Thanks!
Thanks for explaining this so beautifully.
If I interpret this correctly, even if Superdeterminism exists, you can still not predict the outcome of a quantum experiment. To do so, you would have to measure the properties of the measurement device. To do this you need a bigger measurement device. But then you need to measure that device as well. You need yet another device. The story goes on and in the end you need to measure the entire universe, similar as in Bohm's theory. Only an observer from outside the universe has a chance to make exact predictions of quantum experiments within the universe.
Now comes the important point: If you cannot make exact predictions within our universe in principle, then the question of whether it is deterministic or not cannot be answered from within our universe. If a quantum measurement shows result X, you cannot tell if it did so because it was predetermined or if it was random. For that you would need to make a prediction first. It is a bit like trying to proof whether the statement "This statement ist false." is true or false.
That's a valid way to look at it, imo.
No determinism is not true because man is capable of comparing his actions to an ideal standard. A rock falling down a hill does not compare actions at all. A rock had no mind.
Valid point. But if the mind is completely controlled by the laws of physics based solely on physical cause and effect, then what's the difference between the mind and the rock, except the fact that the man with the mind is just aware of his actions? If he has no real control or free will, then does awareness make any difference?

If you were given two lists of "random numbers," one from a pseudorandom generator and one from a "true random" source. There is no test you could do to determine which is which.
Without already knowing the seed, pseudorandom numbers are indistinguishable from "true randomness" if it exists.
For all we know, the randomness of quantum mechanics could actually be pseudorandom and we just don't know what the seed is.
Even if everything is predetermined, the system is so complex that our ability to reconize it as such is impossible at this point. For all practical purposes it is percieved as having choice.

Great talk, and the following may help Sabina without having to spend a lot of money on a new experiment but rather of implementing two other experiments…for a better understanding of physics in general. Something no one else has thought of…
I call it the “Sourlis Implementation”…
Combining the double-slit experiment with the photoelectric effect: Normally these are considered separate experimental setups, but merging them by using a metal plate instead of a standard detection screen is an innovative approach.
The indirect observation of interference: Rather than directly observing the interference pattern on a screen, you are inferring it from the spatial distribution of the emitted photoelectrons/secondary electrons. This adds an extra layer of complexity.
The delicate balance between wave and particle behavior: The ability to switch between observing interference (wave-like behavior) and obtaining "which-slit" information (particle-like behavior) by simply adding the detectors is a quintessential demonstration of the wave-particle duality in quantum mechanics.
The potential for new insights: This modified setup may provide additional insights into the fundamental principles governing the behavior of quantum particles and the measurement process. Exploring the interplay between interference, detection, and electron emission could lead to a deeper understanding into the:
a) Wavefunction, as with no detectors in place behind the slits because of the wavefunction intensity will lead to higher emissions and thus provide insights or interpretation of the wavefunction by this intentional manipulation.
b) It will reinforce superdeterminism and bohemian mechanics.
c) The multiverse theory will have to be redefined.
d) Potential Insights into Quantum
Computing and Information:
Understanding the relationship between wavefunction manipulation and quantum phenomena could have implications for the development of quantum technologies, such as quantum computing and quantum communication.
And more
And this is based on if the observed results match the standard quantum mechanical model, the very fact that we can intentionally control the wavefunction intensity to produce the anticipated outcomes could be seen as evidence supporting the principles of superdeterminism.
The 3 scenarios of results are
1. Wavefunction Intensity play a role as this would be according to the standard Quantum Mechanical theory.
2. Wavefunction Intensity did not have an effect on results which would indicate something a miss with special relativity and that quantum mechanics would have to be redefined without its constraints place on it by special relativity.
3. No emission from plate with detectors in behind the slits would indicate a misunderstanding by mainstream physics, and if this was the case i would suggest the next step would be to remove the slits with leaving the detectors and the full implementation of the rest of the dual experiments intact, and if further no emissions my theory which I have would be of some use, and which lead me to suggesting this implementation being looked into. (Note the two fundamental concepts that the speed of light being constant and that of entanglement being a byproduct would remain yet the Doppler effect would have to be revised).
Overall, the integration of these two foundational quantum experiments has the potential to provide a more comprehensive picture of the wavefunction and its behavior, as well as shed light on the ongoing debate between deterministic and probabilistic interpretations of quantum mechanics, including the concept of superdeterminism.
The Sourlis Implementation
Of the double-slit and photoelectric effect experiments:
Apparatus:
1. Monochromatic light source (e.g., LED or low-power laser) with a photon energy just above the work function of the metal plate
2. Double slit apparatus
3. Metal plate (e.g., thin aluminum or copper foil) chosen to have a work function matched to the photon energy
4. Photoelectron detectors (e.g., microchannel plate detectors) placed behind each slit
5. Voltage source to apply a potential difference across the metal plate
6. Ammeter or picoammeter to measure the photoelectric current
7. Collimating optics (e.g., lenses, apertures) to control the beam shape and angle of incidence
8. Mounting hardware to securely hold the components in place
9. Case 2: Using electrons as the source
10. Apparatus:
11. Electron source (e.g., thermionic electron gun) with an energy just above the work function of the metal plate
12. Double slit apparatus
13. Metal plate (e.g., thin aluminum or copper foil) chosen to have a work function matched to the electron energy
14. Electron detectors (e.g., microchannel plate detectors) placed behind each slit
15. Voltage source to apply a potential difference across the metal plate
16. Ammeter or picoammeter to measure the secondary electron current
17. Collimating and focusing optics (e.g., electrostatic or magnetic lenses) to control the electron beam
18. Vacuum chamber to maintain a high-vacuum environment
19. Mounting hardware to securely hold the components in place
The key updates are:
* Using a monochromatic light source or a low-energy electron source, just above the work function of the metal plate
* Choosing the metal plate material to have a work function matched to the photon/electron energy
* This ensures the photoelectric effect or secondary electron emission is induced, but without excessive energy that could complicate the experimental observations.
Regarding the multiverse or many worlds interpretation…the standard MWI predicts that the wavefunction should maintain its interference pattern and higher overall intensity, even with the presence of the slit detectors, since the wavefunction does not collapse according to this interpretation. However, the experimental findings show a lower wavefunction intensity when the detectors are in place, which appears to contradict the MWI's predictions.
Overall, I believe the MWi can be further developed and combined with other quantum interpretations to provide a more comprehensive understanding of the complex dynamics at play in the combined double slit and photoelectric effect experiment. By exploring the selective amplification or "biasing" of wavefunction branches, as well as the role of decoherence and measurement interactions, the MWI may be able to be reconciled with the experimental observations.
But a case could be made for the MWI whereas the other interpretations could not, and, that would be if no difference is made from the wavefunction intensity (meaning no change in emissions)… explained…
Experiment result #2…
The experiment shows no reduction in wavefunction intensity, even with the presence of detectors.
* This would be a surprising result, as it would contradict the established experimental evidence.
* If verified, it would lend strong support to the standard MWI and its prediction of the preservation of the full wavefunction and interference pattern.
* It could undermine the current understanding of the role of measurement and decoherence in quantum mechanics.
* This outcome would likely require a significant rethinking of how we model the interactions between quantum systems, measurement devices, and the environment.
• It could lead to a major shift in the theoretical foundations of quantum mechanics, potentially favoring the MWI over other interpretations.
I think that the real interpretation is a superposition of all possible interpretations
exactly
Me: "How common or rare is a belief in super-determinism (or strict determinism) among those with PhDs in physics?"
Belief in strict determinism is uncommon among physicists with PhDs, and super-determinism is even less frequent. Here's why:
Strict Determinism: Most physicists accept that the universe operates under physical laws, but randomness plays a role at the quantum level. Strict determinism suggests everything is predetermined, which clashes with quantum mechanics.
Super-determinism: This is a loophole in Bell's theorem, a famous physics concept. It proposes hidden variables pre-determine everything, including the choices scientists make during experiments. While a technical possibility, it's seen as unlikely due to:
Lack of explanatory power: It doesn't explain much beyond the correlations observed in Bell's theorem.
Occam's razor: Simpler explanations (like randomness in quantum mechanics) are preferred.
However, there are a few physicists who advocate for super-determinism, like Sabine Hossenfelder. But it's a minority view.
Love Sabine. But she's such a borderline crank on this issue, Gemini ends up mentioning her (and her alone) by name.
Sounds about right!
"borderline crank" - something like that might have told Albert Einstein too, when he first time came up with special relativity. Trust in Gemini? Well there are some others out there on the field: Tim Palmer, Sandro Donadi, Emely Adlam, Gerard T´Hooft (Noble winner), Gilles Brassard...

Finally a new video explaining the concept of SUPERDETERMINISM!
This new paradigm, even if it may be counterintuitive, seems to me more simple and realistic than the other interpretations because it does not postulate new exotic elements.
It also has the advantage of being completely in line with the Einsteinian eternalist block universe!
That´s right.
What an amazing collab!
10:33 Prior to the Copenhagen interpretation the idea that the observer is exactly correlated to the observation would be the accepted view given the classical view that all particles have fully determined propagation via laws of physics. Only after the wave function/probability theory was introduced was there now a way to escape from the fully determined Universe.
I love you and your channel but I think Sabine is right I'm not ready to give up space time whatsoever
All what Sabine stands for is that more research on the topic is necessary, and of course she´s right. Standard QM has given up to solve an inconsistency.
To me, super determinism is the only thing that makes sense.
It makes the most sense because it maximizes what we don't know while also understanding it all makes sense.
There's far more of the universe we can't see than what we can in the universe and there's far more we don't know than what we know. But when we look at how the pieces demonstrably fit together, it all seems rather mechanistic. The wild card in my mind is emergence; things adding up to more than the sum of it's parts. But, generally I find super determinism to match the closest to how I understand reality.
@@pauljohnson570 It is dependent on your definition of "God"
If (God does and exist) and (the way you understand the universe precludes his existence)
Then, I would assert, either you understanding of the universe is wrong or your understanding of God is wrong.
I further assert its more likely that the understanding of God is wrong because the science is testable and allows for a higher density of agreed upon reality, which gives it more value than that which is unprovable and often used in systems of population control.
It could be that what the ancients called "God" is just the quantum level of reality as they understood it, or perhaps God exists outside the confines of this universe and sees it as a solid state (whereas inside we perceive time).
I don't think it wise to close one's mind to all possibilities that have a potential to be one day proven, despite the fact that they currently cannot be (not to say you are not doing that, just clarifying my approach on the topic.)
just because you cannot measure it, doesnt mean it has not got a specfic value at a point in time (down to the shortest length of time)?, also why does this even have to rely on whether us as humans can or cannot know a particles value?, isnt that a very anthropic (and very arrogant) way of looking at the universe?
@@aristideau5072 what do you suggest as an alternative?
You can predict where that isolated particle will go with certainty, depending how you view it. That particle that gets isolated to fire through a slit is never outside of the field that carries it. Like isolating a drop of water in the ocean to look at. It's still in the ocean and will move in accordance with the motion of the waves. This is just energy we don't interact with till we isolate a particle to look at. A particle is a tiny tiny piece of wave, that never is outside of its carrier wave. You know when you fire it, it will appear with complete certainty in one of the normal wave impact zones on the other side of the slit.

Right away I'll say that I prefer Sabine's approach to SD. On that note, I also think it is "better" than Copenhagen and many worlds. In Copenhagen the measurement is equivalent to the "and then a miracle happens" of those science jokes. It's completely mysterious and taken on faith. Similarly, many worlds depends on "just trust me, there are other universes but we can't ever prove it" because the math somehow allows it. Why would any of these two alternatives be better than simply allowing for all causes and correlations to have been fixed since the beginning? The alternative is some kind of acausal motion, not even probabilistic, but without any reference to the past.
It's why the argument that superdeterminism is unfalsifiable doesn't hold up, since it applies just as much to wave function collapse. If there's no mechanism behind it, how can you prove that's what's happening in the first place? How do you undergrid your interpretation without a mechanism that proves your interpretation correct? Of course, if we did know the mechanism of wave function collapse, then it would cease to be probabilistic in the first place and would render the theory deterministic. It seems paradoxical.
People prefer these because they allow for free will in some way. Superdeterminism strips that away and exposes the illusion of free will (although we still tend to act as if we have it, because it is a great psychological tool to survive without a complete existential crisis).
Where is all this heap of hidden parameters stored? Outside the physical universe on a computer that simulates Elon Musk?
The massive leap in logic to “you don’t have free will!” from an unfalsifiable model involving quantum interactions is just another example of how so much of science is driven by competing politics and worldview. We don’t even know how the brain makes a thought. We do know that decisions are made based on external information and that we experience and exercise free will by any reasonable definition; including the ability to alter our choices on a whim just to demonstrate that we have free will. Rather than free will being preserved by people “afraid” that nothing matters, there seem to be too many nihilists terrified that everything matters.
Thanks!
Thanks so much!
Thank you for the video, it has been inspiring and very clear ! I guess that conservation of information and reversibility would strongly imply superdeterminism.
The universe's ultimate conspiracy theory 😂
Haha...not a bad take!
We observe the universe in the present moment (wave function collapse) surrounded by the observable therefore, predictable past (general relativity) moving towards the unobserved therefore, probabilistic future (quantum mechanics).
Frankly the probabilistic interpretation is the conspiracy theory. And it was pushed under actual violence. Bohr was not nice.
@@binbots you really out here spamming your idea on irrelevant posts? you've more pride than that :P
@@anywallsocket lol that was an accident. Didn’t realize it was in a response section. Thanks for being on top of it.
There is a discussion in law theory that we don’t need prisons or other kinds of criminal justice because of super determinism. Some argue that it’s not someone’s fault to be a criminal because the universe had already decided how the person would act.
But with SD, it is also determined, that the person HAS TO GO to prison.
Yeah that's pure academic stupidity used to justify a particular political view. The bottom line is that even with super determinism at play, you _still_ need to isolate them from society to prevent them from harming others in the future. It's just that now you're destined to do it or not rather than making a choice about it.
It is still their fault, even if they can't control it. The same way you lock up a lion that you know will eat you. The lion eats other animals by its nature. So by locking up a thief, they brain of the thief will remember what it is like to serve time and not commit more crimes. In other words there is a built in behavior that has to be modified , that behavior is what we call the fault. It is a fault because most people think it is very undesirable in society.
Justice is a concept for maintaining order.
so when it comes to sending a convicted criminal to prison... SORRY we don't have a choice! 😂
Superdeterminism is absolutely my cup of tea. But I also add in an epistemological argument against the Copenhagen-etc.-interpretations, and their perpetuation of the status quo of Western Metaphysics. That's all they serve to do. Instead of taking an epistemically agnostic position, so many physicists rush to defend the last hope for 'free will,' while sacrificing all those who suffer by it to their undeserved fates. Is that fair?
@@anywallsocket maybe for idiots

Correction: Actually Copenhagen is agnostic and doesn't attempt to state what is or isn't real prior to observation ("collapse"). Its presumed probabilistic nature is likely the single most frequently misstated feature by physicists about it.
Sure, but Bohr et al essentially tried to avoid the elephant in the room, i.e., issue of what is real, leaving it up to us to interpret what "superposition" means.

If he was proven wrong, why are you commenting in a video that is about an alternative to the Copenhagen Interpretation?
Sabine's rebuttal is shockingly bad. She desperately needs to read some Karl Popper if this is her take on falsifiability.
The crucial part she's missing is that it isn't simply falsifiability that's desirable in a theory, it's a falsifiable theory *that we have tried to falsify, but failed!* - this crucial distinction is the entire crux of the scientific enterprise. It's a process afterall, not some deductive property. What makes falsifiability valuable is precisely the power that lies in carrying out the falsification attempt. Because once we try to falsify a theory, and fail, then we're closer to being correct than we were before, by definition.
Sabine brings up the example of coming up with 20 falsifiable theories, and falsifying them immediately, and concluding falsifiability is overrated, well, duh. Of course when your example is structured that way, it's the conclusion you reach. Look, I can do the same thing with repeatability. "I have come up with 20 different theories to test, and all of them are repeatable - they all fail the tests every time! Look how overrated repeatability is, it's practically worthless!" - is what Sabine would say. Disappointed.
But good video from Arvin overall. I never had a clear picture of local hidden variables prior to this video. Though I do feel like there's some explaining to do when it comes to bohmian mechanics, we have countless QM experiments of conditions changing after we've made a measurement, and the particle somehow taking a different path that should be impossible given our prior measurement.
Did you even listen to her or did you just want to make a self presentation? She´s a leading mathematician and thinker and you are megalomaniac enough to explain her Popper, that´s ridiculous.
"The crucial part she's missing is that it isn't simply falsifiability that's desirable in a theory, it's a falsifiable theory that we have tried to falsify, but failed!" I think you should watch her statement again, because she is essentially saying the very same @18:28 : Having a "falsifiable theory" is not enough, because it is easy to come up with one. It is difficult, however, to come up with "good falsifiable theory" (i.e. one we can and have tried to falsify but failed).
@@Thomas-gk42 How is it ridiculous? Most mathematicians are platonists, they've never read a lick of philosophy. I don't expect Sabine to have read much either. Course I expect her to have heard of Popper, but her presentation made it clear she doesn't understand the value of falsifiability properly.
@@alexanderkohler6439 You're retrofitting her "good falsifiable theory" statement into what I said because it's convenient, but the likelihood that is what she means, given what she said the few sentences prior to it, is negligble. "good falsifiable theory" can mean anything in the world. Just like "good politics" or "good philosophy" or "good science" is a vague term. But nice try.
@@Google_Censored_Commenter I am not retrofitting, because it is convenient, but because it is a fact based on what she started her argument with @18:00 : She argues that the criticism most often comes from physicists which don't keep in mind that falsifiability alone is NOT enough. You need to have some additional properties in order to get a "good falisifiable theory". Yes, she doesn't go into further details by explicitly stating what those additional properties precisely would have to be in order to get the quality mark "good". Instead, she gives an indirect indication by pointing to a ton of "bad falsifiable theories" in particle physics as counterexamples. I think, that is fair enough for a short appearance in someone else's video.
Brillian video.
Please make more collaborations with Sabine.
She´s marvolous.
Well done, Mr. Irwin. A wonderful explanation that is easy to understand for non-physicists

I‘m a non-determinist. Why would evolution select for big brains with big prefrontal cortexes (that decide which action to take), when anything is anyways already predetermined? And the probabilistic nature of quantum effects? And bells theorem? To me, superdeterminism is at best a concept like a closed system; philosophically interesting, but not realistically existent.

Compare to ants, a single ant is not that intelligent, but as a colony they can do amazing things.
@@lemondemerveilleuxdechrist6515 It´s correct.
If superdeteminism is real, couldn't emergence save free will?
If everything was determined, though, what implications would it have on philosophical matters like free will or ethical questions? That's what interests me the most.
If everything is determined and there's no free will in the universe, there's no will at all, no "knowledge" or discovery, no justification behind science or the scientific method, no justification for epistemology since your starting point defeats the possibility of you "obtaining" "knowledge". Things would just be, and there would be no oughts, everything would be a mechanistic soup of molecules... which makes it silly to even entertain, how is a soup of meaningless molecules ever gonna know or justify that claim logically. People need to start looking into philosophy of science and leaving physics where needs to be.
weak emergence means the dynamics of a system of a given level become decoupled with the dynamics of the system at a lower level -- you can imagine it as simply when the higher level dynamics are functions of the *average* of the lower dynamics. strong determinism therefore doesn't lose its consistency, rather it loses its relevance, and indeed, while the universe itself may be taken to 'compute' every nuance and detail of its dynamics, each hierarchical layer distinguishing subsystems needs only 'compute' itself.
The free will discussion is not connected with QM. How does the copenhagen interpretation allow you t have free will?
Yes, free will is a feeling like love, an emergent property of our brain so far.
"Free will"--in the only meaningful sense--is consistent with superdeterminism. Random behavior is neither rational nor moral.
15:37 "No one knows what those variables are, or where they might be."
Wouldn't much of a "hidden" variable otherwise.
15:58 "There's no testable prediction that Superdeterminism makes."
In other words, it has exactly the same amount of uniquely testable predictions as any other interpretation. Which is to say, exactly zero.
I agree with everything you said. I want just to add a few things to your second point:
(a) There are interpretations (objective collapse theories for example) that differ in their predictions.
(b) There are interpretations (Copenhagen) that strictly speaking make no predictions in some cases because "measurement" is not defined. So they differ empirically.
(c) Quantum physics is not special in this regard. Classical mechanics has more or less equivalent formulations (Newton, Lagrange, Hamilton) and so does general relativity (EC, teleparallel, ...). But in quantum physics unlike the other cases people view them more as different somehow and argue over them.
(d) Even among theories that make the same predictions some are better than others. Because if you want to bound the predictive power the "complexity" (Rademacher-Kolmogorovcomplexity) of the model description is relevant. So even empirically equivalent models are not "equally likely true".
One historical example for (d) is heliocentrism and geocentrism with epicycles. You can represent every heliocentric model as a geocentric model with epicycles up to arbitrary precision. But one should be preferred.
For quantum physics I'm therefore of the opinion:
The Schrödinger equation is all there is. No objective collapse process. No guiding wave. ... That's all not necessary and just makes the theory more complex without a better fit to empirical data.
The (deterministic) Schrödinger equation alone predicts an subjective random collapse of the wave function where the Born rule applies. I don't need anything additionally to make this happen or select one outcome objectively for what we observed so far.
@@tofu-munchingCoalition.ofChaos
You know a lot more about this than I do. I've just been watching the various interpretation people go round and round and never seem to make any headway one way or the other.
@@interferon4800 Understandable that you have this impression. But there is progress.
For example the Ghirardi-Rimini-Weber theory (GRW) is from an experiment in 2020 almost completely ruled out. The same experiment also ruled out the simplest version of the Diósi-Penrose model.
And there are further tests for the Diósi-Penrose model (and random gravity). They directly test if the gravitational field is quantum (allows superposition) or stays classical.
I really like the Diósi-Penrose model. It has a conceptual reason (Penrose discovered that where Diósi formulated the model first). It's not like other theories because they dislike some aspect (like randomness for no reason). One postulate in general relativity (equivalence principle) contradicts a superposition in the gravitational field and if you want to make this violation undetectable you get the Diósi-Penrose model.
That's all about (a) so far. But my main point is about (d):
But I also think the discussion in popular science is focused too much on philosophy (philosophical reasons to like one interpretation over another) and experiments (most predict the sane or almost the same anyway).
If you discuss the heliocentric and geocentric model with epicycles this way, it will also seem like both are as good as the another. The discussion online is lacking an important part of the scientific process (statistical learning theory - naïvely Ockham's razor).
I could also make other points (like some very popular interpretations are not even capable of describing quantum field theory only non-relativistic quantum mechanics). But I leave it at that.
btw. I'm not a physicist but a mathematician. And I think that helps me to make sense of the discussions because a mathematical aspect (statistical learning theory - predictive power estimates) is what's ignored and needed.
03:35. Is this the right way to look at it? We view a particle in a wave function. We fire it through a slit but we know where it will land. It is still in a wave so it will land on a high cycle of one of those waves.
We observed a particle, but like isolating a water drop in the ocean to look at while ignoring all the other water, we see that single drop was never out of the waves or fields. The wave function does not collapse. The particle acts like a wave because a particle is simply a point interaction in the larger waves function.
Wave functions aren't descriptions of particles. They are descriptions of unmeasured quantum mechanical ensembles. As such they are completely abstract objects. You will never find any trace of a wave function in nature.

Super-duper-determinism made you read and upvote this comment.
Super-duper-determinism will also cause my 2nd comment, the next one directly after this one, to mysteriously "disappear."
About 15 years ago, I came up with the idea that a totally deterministic universe is compatible with, and, in a sense, necessary for free will - the opposite of what you would expect. Model/Analogy #1: the steering wheel of an automobile would be useless unless there was a deterministic affect on the automobile's wheels when turning the steering wheel. Model/Analogy #2: Conway's "Game of Life" has totally deterministic rules. But, I can determine (steer) the outcome of the game by changing the boundary conditions -- I can add or remove "particles" at any time during the simulation. (Remember, the boundary conditions are not part of the deterministic rules, as they say in PDE class.) Analogously, of course, that means that free will is not part of the universe, but interacts with the universe via a suitable "servo" mechanism, analogous to the power steering assist in an automobile, such as a brain. I suppose it also means that there is something akin to another dimension of time outside of the simulation (universe), that is not the same as the dimension of time inside of the simulation (universe). (I could be wrong, but doesn't LQG also need another dimension of time that is not the same as the time "created" within LQG.)

From this exposition Superdeterminism sides with Einstein in his objection to Bohr's 'spooky action at a distance ', and supports his instinctual response that the glove was already right-handed before the box was opened. Very refreshing, I've always been partial to Einstein v Bohr on entanglement.
Given the relative simplicity of Superdeterminism (compared to QM) I'd accept it more than I do the Copenhagen Interpretation. I'm also not bothered with the thought of giving up free will, so it's easier for me to accept Superdeterminism.
Plus, the free will discussion doesn't even have much to do with superdeterminism.
Regular determinism already is incompatible with the existance of free will, depending on how one defines the prefix "free" in free will.

I don't like superdeterminism, but like a lot your comparison with Sabine's ideas in a video, because I like you both.
0:47 "Can we calculate with certainty where we would find them? (....) ... the answer is no." (the electrons/photons). But see, what this argument ignores is the fact that we don't know WHY we can't seem to predict it. And to focus on that point: You need to realize the real implication of this fact: that you do not KNOW the REASON for this. So what could be the reason that we do not know why we can't predict it? Lets logically list the possibilities:
1: That there IS no reason. That there is some kind of total randomness "affecting"(or rather strangely that there is NOT anything affecting) the positions of the particles. Therefore super-determinism does not exist because it would exclude such true randomness.
2: There is a logical reason to their new position, we just simply have not been able to observe or detect whatever that reason is.
Now lets look at validity and problems of these two possible explanations:
1: To accept this explanation, that there is no reason, would literally require the rejection of reason. It's literally unreasonable! If you believe in this explanation you have to reject reason.
2: All this explanation requires is the realization that we, as of yet, do not know everything and that we do, as of yet, not posses the ability to 100% fully and completely investigate and observe everything. It's HIGHLY likely that there is some forces or effects at play here that we have simply not discovered yet which may account for the seemingly "true" random nature of the particles behavior. We humans are, after all, not godlike beings with the ability to tap into every truth in this universe we live in. It's not just very reasonable to assume that there is still a lot of things we do not understand about the nature of the universe and how it works, we KNOW that, we KNOW that our knowledge is as of yet highly flawed and missing many pieces to solving the full puzzle.
But lets just for a moment imagine that true randomness is actually real that the quantum particles can actually behavior in ways that are entirely without any reason. That there are effects where their behavior is completely severed from any kind of reason. Lets try and imagine that if you can: How would you ever prove it? Since it is unreasonable in nature what kind of reason or logic would you ever be able to apply to determine or prove it? None, there'd be none, by definition. You'd never be able to prove true randomness.
On the other hand we can't rule out the possibility that the means to actually observe any possible reasons may be out of our reach, possible entirely, which could be an unfortunate, but logical effect of the actual real structure of how the universe works. If this is the case the knowledge of the real reasons will forever be denied. One might argue that this then would be what true randomness is. What's the difference between an effect that appears completely random because you are forever denied the knowledge of the actual reason and then actual true randomness that would truly not have any reason for it to happen? Obviously there would be a difference, but the knowledge of it would be unattainable. So in effect: true randomness would appear to be real to us, indistinguishable in every way from actual true randomness.
In conclusion I think opponents of super determinism is in for a rough ride. They certainly have the challenge cut out for them: Need to disprove reason but you can't use reason to do so. At least proponents of super-determinism will always have logic and reason in their toolbox.
Super cool to have you two on one video! I enjoyed.

Whatever the answer, I doubt we will solve the measurement problem until we find out how quantum mechanics interacts with gravity. Some of the most beautiful proposals solve both the measurement problem and quantum gravity with the same idea (e.g., Penose's objective collapse, ER = EPR, Oppenheim's postquantum theory).
Beauty is not a criterion. Theory has to predict experiment, it has no obligations to be beautiful.

Exactly what I was thinking. Seems like Copenhagen advocates have had 100 years to give an explanation of measurement and they don’t have one. The characteristics of superdeterminism seem much easier to swallow.
@@kas8131 Currently this boils down to either preferring to not have a satisfactory explanation of the measurement process or the hidden variables. I prefer not to choose at all for now...
@@kas8131AIUI superdeterminism requires that particles at the quantum level are correlated with macroscopic objects such as measurement devices. That makes very little sense to me. It's not just that an observer has no choice of what measurement to make, but also that the whole configuration of the device including any human intervention is pre-determined according to the PARTICULAR particle being measured. If it was the particle next door, the settings would have been different. Except of course it was impossible to measure any particle other than the one measured, just as it's impossible that we would NOT have the power to imagine otherwise. And yet that power of imagination and apparent free choice has delivered so much order in our part of the universe. Mulling over what might be, or what might have been, is how thought itself is constituted. In other words total delusion proves to be the basis of enlightenment. Such a setup is so wild, I think it's almost the perfect proof of theism. Except of course that theists typically require God to have given mankind free will.
Superdeterminism is hogwash. It is not sufficient to merely state that there are correlations. You have to explain, why and how they lead to uniform results that mimic the quantum theory.
I like superdeterminism. I think people don't like it because its uncomfortable.
The issue of measurement is overlooked too readily, probably because its a very difficult one to reason about. I think it's a hangover from classical physics, but is an assumption which cannot be made at quantum levels.
The issue is, fundamentals of physics research is not seen as needed when the calculations work so well, you can just 'shut up and calculate'.

Thanks for the video Mr. Ash! Another good one!
My issue with super determinism is it gives nihilistic atheists the excuse that nothing they do matters. The universe may be deterministic, but it's fundamentally unpredictable as you can't ever know the starting conditions. The universe may be deterministic, but it will never feel any different to having free will.
No it doesn't. Nothing you do does matter in the scheme of the universe, being an intelligent being able to give yourself meaning is what everyone has to do on their own. Nihilism is to take life at a purely logical scientifically dry level and not inject any humanity or emotion into it. Atheism is completely unrelated.
What if we accepted that all our actions and actions are the fruit of an eternal pattern of the universe? This would change our perspective...

I think you may have meant to say "super determined". 😂
My opinion is, Superdeterminism is the grandchild of the "all-knowing god" in theology. It rejects randomness and describes time as a predetermined emergent block of incidents. While there is still no method that offers a universal, closed-form solution applicable to all scenarios to even three-body problems, considering the whole universe to be strictly emergent without any non-predictable randomness and throwing probability out of the window might be excessively pretentious.
Scientific arguments deserve better than to just be called "might be pretentious". Fundamentally, superdeterminism is about rejecting arguments based on measurement independence and seeing if it can lead you to new predictions. The implications about randomness are secondary and frankly not very interesting.
As it happens, the concept of sin is based on the idea of free will, determinism precludes the concept of free will, which would be a very critical theological problem. "All knowing god" would have to know the starting position, direction of travel, speed, charge, and spin, of every single elemental particle as it condensed from energy early in the expansion of the universe. That could maybe get you to Deism, the universe is god, but that is not what the churches are selling.
The most generous description of "free will" is a cone of potential, looks a bit like a gravity well, it expresses the available freedom of motion (change) for a given object or person. The likelyhood that you will significantly change relative velocity or location much in the next 5 milliseconds is pretty low, where you could be any number of locations a year from now. This is greatly constrained by where you were born, who you were born to, and the circumstances that led up to it. Statistically these factors have an overwhelming impact on wealth and wellbeing, yet it isn't an iron clad indicator for any given individual, the uncertainty principle still applies. (hidden variables)
What makes us truly unique is our experiences, which are by nature biased, the lack of free will isn't the same as a lack of agency, but you aren't likely to radically change your outlook on the world without some cause for that change. This dialog is far shorter than the internal dialog that created it, so just in the first step of communication there is significant data loss, we don't think and reason in a vacuum, our world view colors how we see information, and that colored information shapes our world.
You’re not thinking like a scientist there. God knowing everything about every elemental particle is only a problem if you commit a category error, and assume that a being couldn’t know such things because you couldn’t. No theologian would assume that, nor even the Bible writers. What do you think it means that God is “past our understanding?”
If God was aware of all outcomes upon creation of the universe/the Big Bang, then both humans and God can be in different senses responsible for human actions. Allowing for free will while also knowing all outcomes at conception can reconcile the older theological issue of Calvinism and Arminianism. It’s fascinating stuff, if you aren’t just looking to dunk on churches as if you learned about science from Rick and Morty episodes.
I'm with Sabine on this one, I believe as measurements get more refined, predicable outcomes will increase revealing an underlying super-determinism of the universe. Either way, super exciting stuff.
To me the biggest problem is that people think random, or unpredictable means we have free will but there is no connection between randomness and free will. Are you really free to make a choice if one choice or another was decided by a random event you have no control over in your brain? Not really, you are now just a puppet of random events, not a director so you are being "determined" by randomness... there's just no way out determinism and I think people just need to let go of the whole concept of free will. At least in the tradition meaning of it. No one is telling you what type of coffee you get to drink in the morning. If your "decision" is determined by deterministic events, random events or something we don't know yet forces/events, who cares? You still got the feeling you are the one who made your choice and isn't that's all that matters?
There is no randomness in physics. Randomness would automatically violate energy and momentum conservation. The problem is that non-randomness does NOT automatically mean determinism. It may mean that in a Galilean universe, but in a relativistic universe it doesn't. The 19th century couldn't get past its random/deterministic false dichotomy fallacy because it didn't know about relativity, yet. This is not the 19th century anymore, though... so one could expect people to know better. For some strange reason they don't.
This blew my mind. At first glance and as its presented here Superdeterminism seems to be more intuitively "correct". It feels right. I had previously accepted the Copenhagen interpretation as gospel but never been satisfied by the whole "wave function inexplicably collapses on measurement" stuff.
You had no choice in feeling it's right. Alternatively, it might be the case that the mind, presented with the evidence and conclusions of two different explanations, will naturally choose the more plausible one. The mind isn't determined so to choose--it would be free otherwise to choose if it wished--but finds the choice that more closely follows rational thinking to be preferable.
I think the problem stems from the fact that we’re 4D creatures, part of a 4D block universe, with a perception of 3D objects (with change and motion provided by the unseen 4th dimension), and we have evolved in a manner that allows only ‘seeing’ the past, not the future. So, the future seems mutable and the past immutable… and to us that’s true and real. But from a view outside our virtual 3D reality, looking at 4D space-time, all is not just deterministic, but determined. Could those hidden variables mentioned simply exist as the shape of space-time…as in general relativity’s explanation of gravity?
I was thinking about that! Time perception and free will could be illusions like colors or taste. These concepts might not exist outside of human brain
The question is, whether our universe is a determined shape within this 4D space you speak of, or not.
To simplify it by looking at a 2D-creature with the shape of a point that can move and that experiences the z-axis as time:
Does the creature look like one continuous line through 3D space, or would we see lines branching into multiple possible positions that could be reached by the creature and the manifestation of the "actual position" at z=currently is found by observing which branch it moves along, as we move up along the z-axis.
In that case, the outside observer still wouldn't know what happens in "the future"(higher z-axis points), as the actual shape is "rendering" while we move along the z-axis.
If a particle can go left or right, without it making a difference in the energy potential, why must we assume, that a hidden variable must make the decision for it? If it is possible for such a situation to arise, then two branches should be equally likely and only the rendering of the present moment can show, which branch our observation is on.
I am not saying, that this is the truth, I am just saying, that it is not clear, that the description as a 4D space would force our experienced reality to be a determined object for an outside observer.
@@getziie So we're just characters playing a role and the jokes on us because we actually believe we can determine our fates. But to a true higher dimensional observer watching us on their TV it would be just as absurd as us thinking a prerecorded shows characters can suddenly to something differently. Man maybe Buddhists have it right, just accept everything that happens because it can't unhappen. Just try adapt as best we can with what we currently understand and know because that's all we can do.
Without accepting multidimensionality in all of the objects, any theory is dormant.
@@JodattisLoeschblatt I see what you’re saying. I was imagining the outside observer as outside of time. As able to see the past, the present, and future as one 4D block (as one might hold a cube in one’s hand). To the observer the block would contain only 4D space. Nothing like time (i.e.: no change, no motion). And, in that way, the probability is entirely a perception (or conception) of the creature (us) from within that 4D block. So, yes, you’re right… it comes down to whether there exists a ‘View’ from the outside from which space and time are fixed and immutable. I suppose that’s really what determines the question of determinism.
Thank you both, what an starry appearance 🌌👁️🙌✨👏🏽👏🏼👏🏼
The idea that the universe is unfolding as it was always destined to is a very comforting thought.

@@racookster Indeed. The distinction between determinism and predestination or fatalism is too subtle for many.
Loved to watch this amazing collaboration! ❤
Thank you for the great video. It was a pleasant surprise to see Sabine commenting here.
SD sounds like a discussion of, if there is a God with the entire knowledge of the universe, is he able to predict everything or is he subject to the same probabilistic universe? That's pretty much a philosophical discussion, rather than a scientific one.
I believe the most important part of the discussion is, in your own words, "You can make any non-deterministic theory a deterministic one by introducing hidden variables." I think SD will just be a philosophical interpretation seeking the comfort of getting rid of the "spooky action at a distance" and in my opinion, this search for comfort is indeed a side effect of our fear of a non-deterministic universe.
Correct me if I'm wrong, but some argue that weather events are also non-deterministic and inherently unpredictable. Similarly, one could counter-argue that there is actually superdeterminism at play, governed by hidden variables that no one is aware of yet. That doesn’t change anything except for providing the comfort and belief that we are not completely helpless in explaining and predicting the weather.
Besides, not only the quantum events but any ordinary life event, such as whether I will be the first person on Jupiter, is quite unpredictable. I can still argue that the universe was aligned at the Big Bang in such a way that will make me the first one landing on Jupiter . It is unfalsifiable, yet such a discussion would just be a waste of time until I come up with some of those variables
While I agree with you on your objection of treating superdeterminism as a scientific theory vs. a philosophical one, there is a big error in the argument on weather events. Weather events are governed by nonlinear dynamics that is characterized by chaos, which is fully deterministic but not predictable.
Most interpretations of quantum mechanics seem to be fantasies. Copenhagen, many worlds, many histories, super determinism, ghost branches, etc., etc. Pilot waves seem to make the most sense, but they have all kinds of problems too.
Yep. I don't think Bohmian mechanics makes much sense. The biggest problem I have with it is the idea of a "guiding wave" that somehow pushes a particle around without itself being affected, and how variables can be hidden all over the universe but communicate instantly with a given particle.
@@ArvinAsh
A great video!
It seems that Bohemian Pilot-Wave Theory as is usually portrayed in videos that compare it to other interpretations is rather problematic and dated. I wish that “someone” would do a video on more modern variants on this “theme” that have a historical connection to Bohemian Mechanics but are inspired by more modern “Hydrodynamic Quantum Analogs” that are talked about at the “International Conference on Advances in PilotWave Theory & HQA” and other places. Love the Yves Couder and John Bush research for inspiration.
Tho it seems that the “pilot-wave” is going to require some sort of “new field” that will be a huge departure in thinking.
@@ArvinAsh "The biggest problem I have with it is the idea of ... how variables can be hidden all over the universe but communicate instantly with a given particle." Your problem goes away by choosing the labels for the hidden variables appropriately. If you choose the initial positions of the particles as hidden variables, the hidden variables would essentially be a part of the defining inital conditions. Initial conditions don't change and hence don't communicate. They are just inital conditions and thus fixed.
Apart from that: I really liked your video. It gave a very good explanation of the subtle differences between determinism and superdeterminism that made it easy to follow for me. Thanks.
@@ArvinAshExactly put. Approved. 😊
I would like to see discussions around a pilot wave model where the non-locality between entangled particles is minimized to their last localized interaction so as to preserve the property of locality as much as possible, but still have the non-local behavior we observe between locally prepared entangled particles we see in experiments. Maybe there is something wrong with this approach, but I think it is the simplest and keeps with the intuition that the universe is for all practical purposes local.
If the hidden variable is at higher dimension, we are probably simply looking at the wrong place for clues

.
non-local hidden variables violate locality, which is backed by special relativity. What scientific theory backs objective reality? Nothing. Only philosophical ones like marxist materialism
In my opinion we have no free will, however we have the illusion of free will. That's the saving grace, that it seems as though we are making choices ourselves, although all be do can be directly traced back to the beginning of time at the big bang. Our "choices" were determined then.
You and Sabine having a cup of tea is my cup of tea! On topic: the outlandishness of many worlds and wave collapse theories seem about equivalent to pilot wave theory and the superdeterminism property. Is there a measure for outlandishness?
For me the measure is the degree of magic vs. objectivity. SD has no magic in it, it´s just a property of the universe, we can observe. Believing in stuff like collapse of the wave function by observing it is like riding the unicorn.
Many things seem random until you find the pattern that connects them. In due time we will come to the understanding that the universe is superdeterministic.
I honestly kind of wonder if superdeterminism will escape disprovability by simply being subject to Gödel's Incompleteness. Hidden variables might exist outside of the system they have an effect in (i.e. outside the universe as we can perceive it) and therefore only be subject to formal proof if we could escape our own universe. We might just be forced to accept their existence as an axiomatic fact once all other alternatives have been exhausted and leave it at that.
We observe the universe in the present moment (wave function collapse) surrounded by the observable therefore, predictable past (general relativity) moving towards the unobserved therefore, probabilistic future (quantum mechanics).

At 11:52, the quote from Bell is confusing.
He seems to separate himsel from nature. If you are a determinst, then your 'belief' that you are free to choose to do one experiment rather than another is in fact *just* a belief.
Regular determinism means that "the boundary conditiosn of the unvierse" already predetermine what experiments and decisions and measurements you'll do in the year 2024.
So why is this called superdeterminism, when it is just regular determinism?
Is it just that the corrleations are *relevant* to the experiment enough to impact the result?
All of this is a result of physicists confusing determinism and predictability, as if they're the same thing. They are not. The universe can be deterministic and have non-predictable pockets at the same time. Wolfram refers to these as as "pockets of irreducibility", and he refers to the universe as computationally irreducable. It's a much clearer way to think about all of this.
Pretending that the local environment is not influenced by the environment around it, as if it's somehow magically disconnected and you can magically isolate objects, is absurd and it's surprising this ever became de-facto. Everything is influenced by everything, and it goes back to the Big Bang. We will never know these starting conditions.
Any model that is not superdeterministic is suffering from the same loopholes and obvious logical contradiction as any model that allows for isolation of objects as if they are not in a universally sized environment. The observers are included in that environment, and their behavior is deterministic as well.
The whole notion of "hidden variables" is also subtly misleading. We're viewing all of this incorrectly because of the choices of terrible terminologies physicists have given us, which has the unfortunate side effect of forcing people to look at reality through a particular constrained lens. Kind of like "dark" "matter". Physicists are notoriously bad at naming things.
If you want to think about all of this clearly, think about it in terms of computation and cellular automata. Look into Wolfram's work. Or if you'd prefer to hear it from a physics Nobel prize winner because you have an appeal to authority bias, look into Gerard 't Hoofts "Cellular automaton interpretation of quantum mechanics". There are no "hidden variables", there is simply the state of the universe at each time step. There are rules that govern the evolution of the universe, and these rules are the initial starting conditions. That's all you need. This still results in unpredictable and irreducible behavior. It still results in pockets of predictability. It still results in superdeterminism.
Anyway, physicists will never embrace this because, as mentioned in the video, they have a religious issue with the notion of "lack of free will". But the issue is they aren't even viewing free will correctly to begin with. If we live in a computationally irreducible universe, it doesn't matter if we technically don't have free will, because the universe is non-predictable. So for all intents and purposes, we can consider ourselves to have it, with no issue.
Further to that, for them to embrace this idea would give them far less b.s. to sell to the public. Their industry requires complicated scifi mumbo-jumbo to keep the wheels spinning, to sell books to the masses that don't know any better, and continue to dripfeed investors. Kind of like how the billion dollar cancer industry would completely crush itself if it developed a cure for cancer tomorrow. No surprises that we still don't have that yet either.
Superderminism is real thing. And very simple to explain if you know about two things. Cellular automaton theory and computability.
Simply put, in very simplified explanation, to be able to predict next state of the universe, thus of any particular part of the universe, you would need a machine with say "memory capacity" of size of number of all elements in the universe. Intentionaly using word elements rather than particles, as we currently don't know what are the building blocks or smaller elements are. But this is not in collision with what been said.
Thus even every moment or future state of the universe is perfectly predetermined, it is not computable due obvious physical limitations. We simply cannot build a machine of the size of our universe within our universe. Righ?

All equations which have an absolute time parameter 't' are wrong. You can think of time in mechanics like acceleration. It's easy to see that acceleration doesn't exist without an interaction and disappears the moment the interaction is removed. Once you get that concept, you still have to explain how you get an effect without cause before entering your own interpretation of determinism.
@@bnielsen56 Time is that which the clocks show. We try to teach this to our kindergarteners, but most of them aren't paying any attention. So what were you so busy with that you weren't paying any attention in K-12? ;-)
If super determinism is true, it still does not eliminate the possibility of free will. If free will exists it must come from something outside the known physical universe. And the initial conditions of a super deterministic universe still come from an unknown source. Therefor it may be that quantum retro causality carries our freewill choices all the way back to the initial conditions in order to fine tune those conditions such that the choice you want to make at this time is made.
It may also be that time is simply irrelevant in the realm where free will choices are made. In other words, our free will choices may be the source of the initial conditions of the universe.
Interesting ideas! Could the initial conditions set in motion the precise sequence of events necessary to create the universe in the first place?
I also think that consciousness is not algorithmizable and therefore cannot be deterministic. Moreover, a hypothesis that is by definition unconfirmable and at the same time irrefutable is absolutely worthless.
Obviously an avid fan of that youtube channel that seems to have an interview every other day on this exact topic. It gets too far from “science” to be … Also Penrose’s “retro-activity” seems to have something to say about this topic.
Certainty (predictability, syntropy) is dual to uncertainty (unpredictability, entropy) -- the Heisenberg certainty/uncertainty principle.
Randomness (entropy) is dual to order (syntropy).
"Entropy is a measure or randomness" -- Roger Penrose.
Syntropy is a measure of order -- certainty.
Super determinism is dual to super non determinism.
Making predictions is a syntropic process -- teleological.
Teleological physics (syntropy) is dual to non teleological physics (entropy) -- physics is dual.
Information is dual.
Average information (entropy) is dual to mutual or co-information (syntropy).
Sine is dual to cosine or dual sine -- the word co means mutual and implies duality!
Mutual or co-information is used to make predictions -- syntropic!
Concepts are dual to percepts -- the mind duality of Immanuel Kant.

Repetition (patterns) is dual to variation (randomness) -- music is dual.
@@ArvinAsh Good Question. Who knows. But can't rule out the possibility that the creation of the universe was the first act of free will.
We are living in a simulation where the random number generator results in quantum randomness.
Even a random number generator is predictable in theory

The most important local hidden variable is time. In Newton's framework, timekeeping is the same everywhere. But in Einstein's framework, timekeeping is local, and varies with the strength of the local gravitational field. For a state variable that is time-varying, the phase of the state variable at any given distance, x, depends on whether the distance x is known to within a fraction of the wavelength of the state variable. For photons of visible light, that requires knowing x to within a few angstroms. Were Bell test experiments done with microwaves, one would only need to know x to within a millimeter or so to be able to reckon the phase at distance x. If you don't know the phase at x, then the best model is that it's random. If you can reckon the phase, you have the prospect of determining how a microwave photon might refract at the edge of a grating.
Bell adopted the simplifying assumption that spacetime can be modeled as Newtonian, which makes his derivation easy. Had Bell admitted Einstein's model of spacetime, he would have been obliged to employ a gravitational path integral and his state variable would not have vanished, but would have yielded some kind of non-vanishing "beat frequency" term.
We know that qubits tend to decohere with distance, and one ineluctable cause of such decoherence is the presence of gravitational gradients in the cosmos, which destroys the possibility of perfect phase-locked synchrony of qubits separated in space. Mathematically speaking, it means we cannot blithely assume λ(x,t) ≡ -λ(-x,t) because the age, t, of the qubits at ±x cannot be assumed to be exactly the same. Since λ(•) cannot be assumed to be an odd function, we cannot claim that it vanishes from the integral that Bell employs in his classical (Newtonian) derivation.
The description of pilot wave theory was enlightening. Thanks.
Adding hidden, unknown variables is like saying "I don't know". This is fine, as we know much less than we don't know.
We don't know and may never know, but we may still have a theory as to why this is so.
Nice
Super-determinism is absolute BS. I am so surprised that so many people believe in it, even the PhD ones.
Beyond that meaningless statement, any arguments?
An unfrofound opinion does not help at all. There are no better arguments for the Copenhagen interpretation.

Superdeterminism (SD) is just another way of refuting true randomness. It is similar to information technology (IT), where computers cannot create true randomness with pure computer technologies spontaneously. You can make random generation complex, but it will always result in a pseudo-random procedure.
SD is a real-world analogue of pseudo-randomness. If you make pseudo-random generation increasingly complex, it will become more difficult to distinguish from true randomness. However, with enough effort, you can always prove it to be fake.
The real-world complexity of randomness makes it too difficult to prove as pseudo.
@@gonavygonavy1193 Occam´s razor supports standard QM and the magic about it? That sounds ridiculous.
Doesn't superdeterminism somewhat kill the science? Since if there's no operational independence then how do we know we really even ask the right questions / do right experiements to begin with because the questions we ask are predetermined?
You´re just parroting what all the biased people say.
Apparently no. Sabine has a couple of very good videos answering this problem.
Thanks for this wonderful video! When I was a graduate student, long ago, I tried to solve the measurement problem, not knowing that the correct answer (decoherence) was being developed elsewhere. That led to the many worlds interpretation, in which all possible futures exist somewhere in some pattern of the wave function.
The common interpretation of that interpretation is that therefore the world is deterministic because if every pattern of waves in the wave function keeps on rolling on, and we are unaware of them solely because "our" wave pattern no longer interferes with the others, then there is a "them" equally unaware of "us" in their wave pattern. If every outcome happens "somewhere", then the only thing we can say about ourselves is that we are the version of "us" that just happens to be in this particular part of the wave function. Ergo, no free will.
I came to the conclusion that there is a mistake - not in the theory, but in the way of looking at it - that not only rescues free will but makes it, if anything, more likely than determinism, even if one accepts every assumption behind many worlds. It is a long story to explain, but I am close to completing two novels (yes, novels!) that explain why. Hopefully the first will be out before the end of the year, so if you are interested, look for "For Selenya" and its sequel, "For Katenya"
Now your excellent video has given us a neat summary by Sabine (clearer than her longer versions, imho) of superdeterminism. And it became clear that the same oversight is happening here. IOW, even if all the assumptions behind superdeterminism are correct, it still doesn't say anything about whether free will exists. I'll now have to bung that in somewhere! :-)
Very best wishes for your future research! Cheers Ron House.
"...it still doesn't say anything about whether free will exists." - exactly 💯! That's what all those half-intelligent philosophy-guys don't get, and it's what Sabine constantly explained a hundred times. U admire her patience.
