It means classical physics is actually naive.
*Hi Cindy - - it means that CONSCIOUSNESS affects the natural world. GREAT video - - Cheers* 😊
I have a theory here: electromagnetism and electric field itself is not quantized, but the effects on particles it is, that's why you can observe single photons interferencing with itself. In reality there are electomagnetic waves emitted but they are too weak to trigger any measuring device. Prove me wrong.

What effect does the "measuring device" have on the photon? 1:29
What has been demonstrated is that this measurement device affects the photons, not that the photon knows it is being observed.
I think there is another exp were measurement got delayed and the system behaved like particles. So is not the measurement device, but the fact that it will eventually get measured, that make it behave like that 🤯
@@tomich20 yeah, before being measured it showed interference characteristics but after delay when it got measured, the characteristics instantaneously changed to photon
Yep iirc this is one of the main hypotheses put forward as an explanation for this phenomenon.
I agree her definitions and loose use of words is a not describing the effects accurately.
Wrong
It is impressive that these physicists managed to isolate a single photon
No one has ever explained how they did it. In other words: BS!

If physical reality manifests out of consciousness rather than the other way around then this makes complete sense. Everything is in a state of infinite possibility until the light of awareness shines on it at which point it manifests into existence
Ding ding ding. We have a winner. Also on that note everything is one and therefore we're all gods in a way as we can manifest whatever because all is us and vice versa anyway. Religion was made to take away our power and god was firmly placed outside of us to achieve that end. K byeeee

I think this is it. Using a graphics engine as an illustration, this experiment shows how the assets are rendered rather than show that we live in a simulation.
whose awareness, though? All organisms? or only humans?
This sounds exactly like Heisenberg’s uncertainty principle, in which a particle’s momentum and location in space cannot be determined at the same time, leading it to have multiple positions at once until observed. The same can be said about Schrödinger’s cat. In this thought experiment, a cat is in a black box with some poison. Next to the poison is a radioactive source. When the source reaches a certain count rate, the poison is released; the thing is the decay of the radioactive source is unpredictable, so cat at any point in time is both dead and alive until observed. Another analogy is if a tree falls and no one was there to hear or see it fall, did it really fall?
Both theories have been used to question the possibility of a multiverse where every possible outcome generates a new universe.
The idea of life being a “computer” program is logical, as almost all aspects of nature have mathematical attributes that are perfectly related to one another. Every possibility follows certain “coded” rules/axioms to carry out. In that case mathematics and physics is just the study of reverse engineering the program of the simulation. But when you reverse engineer a program and come across something that shouldn’t run, like photons arranging themselves when observed, you question whether this is intentional or an undefined natural error. It breaks the algorithm that we have documented for centuries.
The Heisenberg principle and Schrodinger's cat are derivations of this precise phenomenon.
Is math something created or discovered, either by the simulator or simulated?
We should be glad it hasn't been programmed by Microsoft or EA. HAHAHA
Interesting tying this all together, schrodinger's cat makes sense in this context, used to think it was a logic thought experiment (rather than trying to understand a physical phenomena)
Yes, the tree fell. But did it make a sound if there was no one there to hear it?

MarcusAgrippa,
To say "Be happy in who you are" is useless. It's up to You to learn that.
Having known a very smart man, i'd say the less one knows ( within limits ) the happier one is.
The smarter one is, the more one finds themselves surrounded by infantiles and morons on an intellectual level. Imagine dealing with 5 year olds continually. Always passing on knowledge and wisdom, seeing it ignored, and never learning anything from them. Strictly one way knowledge. Maddening . . .

Server admin: oooh they are observing, yo zuckerberg, change the code!
The problem begins with thinking of particles.
That’s interesting, are you loosely suggesting that, since we humans have theorized and done the math to believe they are particles, that’s what the wave ultimately displays…? Because it is a wave of probability after all.. I have thought about this before as well. I wonder if there’s another intelligent specie on another planet who went through a similar process as us, but instead of them theorizing about particles they theorized and did the math for something completely different, and what if that’s what they detect when measuring their versions of “particles”. idk, hope I made enough sense for you to understand me lol.
@@Stampedby__bonetti I wanted to say, that if you go into a theory with preconceptions that are too strong, you always will miss some important traits. So if you are tuned to see particles, you will see particles. It's like looking at clouds with pictures of animals in your head. But the same thing will happen, if you look at the former particles with an idea of probability waves. Both are concepts, that work quite well under certain circumstances. And both will fail under others.
Most people think, physics is about finding out how exactly reality looks like. But the first hard lesson is, that you can't. But you can find out, how reality behaves. The models and theories are made to understand that good enough to make smart predictions. And the analogies, like "photons behave like particles" (IF observed in certain conditions!), are made to get familiar with that stuff.
Let me mention one last point, if you're still sticking to a it"s one or the other idea.
Ask yourself, what a real particle would be like. A solid orb? Made out of what? Which diameter? Homogenious or not?
And how the heck would a complex probability function look like in reality? Etherial Numbers floating in space and time with real and imaginary parts?
So don't ask, what it is, but how it could be described best to make the maths consistent with the measurements.
Sorry to say that, but studying somehow demystifies the whole stuff, and i could have known.
Undestand that the term "observe" in this video means "interfer".
To "observe" the eletron they must use a photon.
Thats why its change from waves to particles
How are we still proliferating this misconception? The behavior of particles change when we "observe" them because "observing" something so small means we have to bump something else into it (like the way electron microscopes work).
The trippy part is the superposition of particles (which allows for the photons to interact with themselves).
What do you expect of a video that is claiming we are living in a simulation?
Might as well title as “Proof that super advanced aliens exist that collapse electron wave function”

How do you explain the version of the experiment where they scrambled the results of which way knowledge after the light hit the detector with the “observing mechanism” (polarized filters) operating and in place - and the wave function reestablished every time the scrambler was turned on? The only variable appears to be knowledge in the mind of the observer.

Thanks! Really appreciate it
Our world is amazing! The concept that the particles could change when being observed seems like a small change in variables but the consciousness awareness effects it in such a way that had plenty of people stunned! Even to this day people are amazed by this experiment!
@chetsenior7253 let's pretend your English was grammatical; are you saying it's asinine because you yourself was not present for the demonstration of the experiment and therefore how can you know for sure? Or that you can't trust what you seen?! And what's with (...) Are you planning on adding to your thought process or are you using ellipses for some sort of effect? Honestly you may want to revise your comment😪😂💁
This is ridiculous. It's not the "mere act of observation" that causes the superposition of a quantum particle to collapse. You cannot "merely" observe a quantum particle. You can't just whip out a microscope and have a look. To observe a quantum particle, it must interact with another particle, and it is the interaction, not the observation, that causes the collapse of quantum superpositions.
Exactly. She doesn't know anything about videogames either. They are not related in any way, a game is predetermined from the start, bound by rules even if its random. It culls objects out of view because its a waste of time drawing them, but they are there. The wave function algorithim itself follows rules based off the input. You cannot predict where a photon will hit, only the probability.
Nope. Based on experiments, even if the observation is done AFTER the photon has passed either of the slits, the photons will still behave as particles. With no observation, the photon will behave as a wave.
@@jkturtle So the observation retroactively changes the photon from wave to particle, so it's time traveling?
@@josemonge4604 yes. And it's wild.
You are wrong. Clever people managed to do it without direct interaction long ago.

That version of the experiment is unsettling.
This is an okay explanation, but not a good conclusion.
Simulation is not the word. Synthesis is. If it were simulated, it would be violating physics. It doesn't.
A synthesis doesn't violate physics. It's too perfect to be real, and it's highly statistically improbable, but it doesn't break laws.
The double slit experiment describes the nature of consciousness as an input. As an input, it changes experimental outcomes and directs our actions.
It does, in fact, suggest that there is a God.
Simulation doesn’t mean “violating physics”… synthesis isn’t even a word to describe what’s going on here lmao. Learn what definitions mean. All this suggests is that there is a creator or creators, not necessarily a god.

Hi!
For a long time I have wondered what exactly we mean by saying "when the photons are observed" and I encountered this video when I tried to look it up. I'm a chemist and have learned from analytical chemistry that we can't measure anything without it interacting with the material of the detector. I was of course curious in how we exactly can "observe" something halfway through an experiment without fundamentally changing the experiment and therefore likely the result. So when I heard that "scientists used a measuring device to observe the slit that each photon passed through" it obviously peaked my interest. From my understanding, and please correct me if I'm wrong or misinterprets the experiment, the so-called measuring device or slit-detector is actually polarizing filters which do not perform any kind of measurement or detection themselves. By only filtrating forth polarized light from each slit (which I think are perpendicular to each other), it would presumably be possible to identify which photons passed through each slit later on. If this is the case, I think it is an extreme stretch of the definition detector or measuring device if no observations, measurements or analysis were performed by this so-called device. I realise that this is likely an extreme simplification made in order to illustrate other points, and while it is false (at least from my interpretation of what a measuring device is), there might be a valid argument that "we might as well view it as a detector for the sake of simplicity". So there is no magical detector. Darn it, another childhood dream squashed.
I still have some issues with general statements I've encountered such as "the photons change their behaviour because we observe them", which likely are simplifications of "in an experiment in which we tried to observe the path of the photons, they behaved like particles instead of waves". While I don't think either statements are necessarily false, they both seems a bit misleading if left on their own. From my perspective, the experiment when using the filters is, at least to some degree, fundamentally different from the one without filters. We can observe "that perpendicular polarized light behaves like particles instead of waves when passing through the slits", and don't get me wrong, it is definitely a interesting and wierd result that clearly illustrates the wave-partical duality of photons. However, to draw the conclusion/interpretation that "they behave differently **because** we try to observe their paths" sounds rather backwards to me. While it is true that we set up the experiment in order to determine their path, a less misleading way to express the result could be "they behave differently because we fundamentally changed the experimental conditions, i.e. we removed all photons that didn't exhibit certain properties (i.e. a certain polarization)". While this might be obvious for physicists and chemists alike (that we can't measure anything without interacting with it), I don't think it is as obvious to people with other backgrounds. The slit-detector is often breezed over in explanations of the experiment and is therefore more or less implied to be a passive observer. A reasonable explanation for this is that we can't explain everything in a 6 minute video. We would need to explain what polarized light is and why that is significant. Easily understood explanations are without a doubt important, and can be justified even if they oversimplify things (such as the slit-detector). However, when doing an over-simplification and just saying "we just observe the photons" it would be easy, and I think very reasonable, to add a large shining caveat saying "the detector is not a passive observer and that it by its very nature may influence the outcome of the experiment".
While this likely would result in some confusion, it would more importantly raise questions which are the bread-and-butter of curiosity. I genuinely think that Newsthink and physicists in general only have the best intentions in mind, but I find this sort of explanation (without any caveats) unnecessarily misleading nonetheless. While interpretations such as "photons change their behaviours/properties **because** we observe them" are alright to make, I personally find them missing the mark of what the actual experiment was about and what the results really showed (i.e. if I understand things correctly). Is it possible that the photons behaviour changed **because** we tried to observe their path? Yes anything is possible, but I find it rather speculative (to put it mildly) if this is the only data that they base it on.
In general, while it is easy to say "You should stay sceptical even when experts explain something" or "Of course the experiment is more complex than it seems, we're talking about physics and the video is 6 minutes long", I don't think that's something we should expect people from outside the scientific community to always take into consideration. And that is why i wrote this post (also because I wanted to know if I've misunderstood something). I would also be very interested for any information regarding other real experiments (i.e. not thought experiments) that deal with "whether photons behave differently if "observed"".
Have a nice day!
Wow
You're correct about the polarizing filters. Each filter blocks out a certain direction of the wave, x y or z. By combining two different polarizing filters you should be able to block out the x and y directions of the wave, for example, leaving only the z direction. It's true that these filters aren't "measuring" or "observing" anything in the more common way that we understand those words, but I think they do "observe" the light in a more quantum/abstract way than we probably understand. I'm a biologist though so definitely not my field of study.
@@SpencerfromEarth hi, thanks for your response.
It’s good to have confirmation about the filter blocks, so thanks again! After I wrote this comment, I spoke to a physicist friend of mine and thought a bit more about the experiments. Most of my criticism stands about how the concept was described in the video but today I wouldn’t have added the comment about that “I find it very speculative to say that the photons behavior changed because we tried to observe them”. I still find it misleading and very easy to make far-drawn conclusions from it, but I was also a bit too focused on the experiment where many photons were sent in and not the experiment where one photon was sent at a time. There is, as you say, clearly a quantum mechanical phenomenon happening at the filters as shown by the latter experiment. So it’s very likely that it also happened in the first mentioned experiment (where many photons were sent), so it’s not only that polarized light interacts differently than unpolarized light which effected the result. It’s therefore really a question of semantics, and while it could be interesting to delve into a deep philosophical discussion about what “observing” really is, I don’t really think it’s worth it. As I’ve mentioned, I personally don’t like the word *observing* to describe the phenomenon, but I don’t really expect people to care much about my stickler tendencies.
Hope you have a nice day!
wow, I had GPT to make it simpler for me to understand :p
I agree. In fact it's so misleading that you get people coming on the comment section talking about how this proves the universe is conscious... People love a good fairy tale.
This is the most excellent explanation of this set of experiments that I've ever seen! Very clear and well laid.
My theory:
There's a good chance that we haven't discovered an unknown energy that is Emmitted from every partical and so does from a camera sensor and from electrons
So the camera tries to observe
Electrons and camera sensor's energy entangle and lead the electrons to behave like a partical
This makes more sense to me
This is the greatest theory of all time for someone who spelled particle wrong

I was sleepy when I wrote that comment
I still don’t understand. Which slit was the photon emitter pointed at? Was it pointed between them? Nobody ever mentions this when describing the double slit.
I need the answer too.
so what does observing/watching actually mean?
to see something you need a photon to reflect from a thing you want to observe and land on the observing device (i.e. eye)
so when you are watching photons, you are hitting the observed photons with another photons - and that just changes the observable photons directions
No
@@straighttalk2069 'No' ? That's it ? That's your answer. Kindly explain if you want to be taken seriously
Yes, for most interactions, but photons do not directly interact. To observe which way, special crystals that split the photon in two can be used so that if the photon travels through one side, one photon can hit the screen and the other can hit a detector. All of these interactions still impart momentum which affect the outcome. MIT OpenCourseware has a great lecture series on this that actually gets into the math but also explain it clearly.
Yours is the first comment I see in this video that challenges the asenine solipsistic rubbish this channel is pushing. Bravo
I dont understand why awareness is ignored by science
Maybe when no one is observing me, I become wave like.
A possible reason is the way that light bounces off an object into our eyes if some sort of thing is reversed or bounces back, it could be interfering with the particle, hence changing its state this would have to be something to do with new set of physics laws, which we currently have no way to prove
First time I've heard a source mention the similarity to zone-loading in video games explicitly. I've long thought of that when considering this subject. It's a good analogy, with so many gamers out there these days.

.....finally at the end of the experiment, the photon sued the creepy scientists for invasion of privacy, anxiety , mental trauma and character assassination 😄
Yeah, and then the particle changed gender.
🤣🤣🤗
ikr! peeping larry peeped the particles. so hawt!
I’ve seen a lot of people saying it’s the physical interaction of the observing device that interferes with the photon, by “bumping” into the photon and causing it to change. To reiterate, if the device is turned off, the photons return to being waves. So once turned on the observing device must be emitting waves or particles that interferes with the photons and causes it to act like a particle.
This makes the most logical sense to me as well. A photon behaving like it “knows” or has “consciousness” seems less likely to me.
So my question is, what if we put more than one observing device in the experiment? For example, one device pointed down (eagle view), another pointed to a horizontal view, and one behind the photon machine. All devices turned on. Would this change the outcome of the pattern the photons make? Would different amount of devices and angles yield different results? I’m not sure if this experiment has been done. I’d love to do it myself but I figure it’ll be difficult to get your hands on a photon shooting machine.
Thoughts?
The quantum eraser, delayed choice experiment disproves your theory.
I’m sure they have tried that and it’s the same….. even you will act differently when observed

We’ve known this for awhile, and while interesting on its own, it brings up an even more interesting thought:
“Does the observer not only cause the collapse, but also have an affect on the final state?”
The observer is irrelevant. An interaction collapses the wave and that interaction can be by a detector. The observer may or may not look at the detector, it does not matter. From the final state, it is often possible to tell where the wave was detected.
@@haroldnowak2042 - Prove it. I've seen no evidence to suggest that the collapsed result would be identical, regardless of observer.
@@cidnewman8032 Remember, the observer must interact with the system via a detector to be an observer. The double slit experiment can have 4 possible outcomes depending on where the interaction (or detector) takes place: Well before the slits, near the slits on the source side, near the slits on the screen side, near the screen. The observer can leave the room but as long as the interaction or detection takes place at those locations you get identical outcomes in general. Similarly, if you move the screen toward the slits the pattern changes from a double slit interference pattern to 2 single slit interference patterns but never to 2 single slit patterns with no interference like when the detector is on the screen side of the double slits. The observer needs the detector to interact with the system and the observer observes the detector. The observer does not have to observe the detector, the system will still do fine without the observer.
This confirms that the universe is against me
Bro!!! 😮😮😮 I'm loving Physics.
That's probably why you can always tell when someone is looking at you
Evolution of the Eye Ball begins in the translucent environment , before it discovered the transparent environment. Atmosphere obviously plays on light density and refraction. The slits are shown on a flat stencil against a flat wall representing a stop in space time continuum. I think results would be different if the stencil was curved against an opposite curved wall . Using black paper against black paper is different from using transparent or translucent emulsion against a solid wall .
We must flip on/off the observer camera like a strobe light and do it faster than the speed of light so that the light particles cannot keep up with the observer camera and be able to react fast enough, then we can see what up. However this might cause the light partical to go backwards as if time is being reveresed. We need mirrors to bounce it back the right direction as the camera is now observing light going backwards in time, i think. lol
Do you remember mirrors reflect light?so electrons would just pass through it too.a reflection is just light bent by the mirror
@tshade Electrons that make the light?. So, what now? It passes through a mirror or something. I dont know lol
Isn’t a simulation considered to be a designed creation? (: The Developer really knocked it out of the park with the whole perfect ratio and the Higgs Boson.
Some people believe that the universe we live in has many more dimensions to space, and as the universe has cooled, these dimensions curled tightly around each other. Now to 3D observers, we are convinced there is no more dimensions than 4 to our universe. 3 of space, 1 of time. The ratio these dimensions curled around each other is the golden ratio.
And the Higgs field. Which is an active massive universal field, which all other energies permutate within. The Higgs boson is an exotic particle that was theorized to exist toward the beginning of this universe and which split off into and collapsed into everything else.

Why are people who know absolutely nothing about physics so fascinated with an experiment from 1801 that every kid can do at home? Exactly. Because they know absolutely nothing about physics. ;-)
Can you imagine how confused they were trying to figure this out?
I am absolutely sure there are some weird invisible ( to our eyes ) beings all around us laughing at us and causing endless misery for their enjoyment. Everything being recorded as if in some alternate reality. Well maybe not that basic, it's hard to express in words, but I get the impression that most humans get a feeling at one time or another/ or many times, that you are being watched by something unknown. One time when in Europe I accidentally took a large amount of a unknown psychedelic ( long story ) it keep me up for 4 days and I had thought I went mad. During this time a weird world revealed itself to me, there were these red balls like eyes everywhere constantly watching and monitoring every movements we humans make, you know the red eyes in the matrix sentinels, well I was seeing those things literally everywhere all around us, you moved and it followed your movements like a lens in a camera. There were millions of these things everywhere I looked. I hadn't seen the Matrix film back then as this was in 1993 and the Matrix wasn't released until 1999. You have no idea how terrified I was when I saw the film for the first time and those red eyed sentinels were in the film. Its not a coincidence that most people feel weird when looking into camera and asked questions or told to say something..
Those weird invisible beings you speak of are demons. Psychedelics cause humans to see into the spiritual realm. The truth is that demons do watch us, but so do god and his angels. If you believe in Jesus, demons secrets are revealed and they no longer pose a threat.
What is there to even laugh at? we repeat our mistakes repeatedly. If anything, it calls for disappointment. Our actions are very predictable even for us, let alone to our god.

HELP ! There's something I can't get my head around this experiment. How do we know how photons behave when they are not being observed?
As far as I understand observe here means viewing the photons on their way to the screen, when we view them moving they fall on the screen as particle would after passing through two slits and when we don't view them moving, they create an interference pattern on the screen like waves do, thus the wave particle duality

I think a more subtle explanation can be made thusly; it isn't the measuring device that is causing the observed particle behaviors. It's our observations of the measuring device. Or, more succinctly put, that consciousness itself is what is causing the interpretation. Consciousness IS observation.
I think you're totally right. Somehow, the event of light being a particle or wave and consciousness observing it are linked at a quantum level; existing creates quantum events entangled with light picking a location
Easiest way to know this. Walk with a full cup of coffee. When you don't watch, there is no turbulence to the coffee in the cup while walking and no spill.
The bigger question is if there was no person or thing in the forest to see or hear the tree fall did it fall?
Yes
We’ll never know lol
If a tree fell in a forest with no-one around except a blind,deaf man,directly under the tree,would he be killed by the tree that may or may not have fell after all?

Interesting....thanks for this. There is also the water experiment which consistently shows an interaction between the water molecules and the mind of the observer.
This test needs to be conducted with several animal observers. If this effect is only observed whether or not a person views it, or whether a person has the potential to view it via a camera. This would prove that humanity is of a higher priority in existence and would suggest that there is a deeper meaning behind this experiment.
When we observe, the observing machine interferes
One explanation for ordinary light and lightspeed is that light is prismed from a higher dimension. This means where light is can only be measured using probability, explaining why it never follows patterns like a hard, precise object yet is one.
The thing that gets me is how the photons create an interference pattern even when shot one at a time.
They're like little magicians 😀
Because they are in whats called a superposition which they are acting like a wave and particle both at once so the particle could be anywhere within said wave
we are living in a simulation. the properties are built into the building blocks of our simulation. so when we start observing, it loads in like how we load in the rendered assets in a video game
Every "serious" proposal of the simulation theory has always been walked back. Because it's beyond juvenile and ridiculous and breaks down at any legitimate investigation.
The possibility of Devine creation is taken more seriously than simulation theory.

How do you, or a detector, 'observe' a tiny particle without some way interacting with it, and impacting its behavior. In our macro world, we can see a baseball without interfering with it. But when you are trying to detect a single photon or electron, how do you do that without interfering with it in some way?
The universe needs an update

From how many angles can the head of a pin be observed?
Then, from how many angles could our own milky way be observed?
And does a mirror reflect a finite or infinate number of reflections at all times?

There's one reflection but an infinite number of angles from which it can be viewed. Same as with the original.
Very nice and concise video on the subject, with clear explanations and just enough mystery left for viewers to be curious.
I've been exploring this and related phenomenon for over a decade, and still your presentation captures my interest - makes me remember how I felt when I knew about it the first time.

What was the rationale for conducting the double slit experiment in the first place? I mean, did someone correctly hypothesize the results of the double-slit experiment?
They conducted the double slit experiment in order to follow up on the success of the single slit experiment. Next is either the triple slit experiment or the double double slit experiment, depending - then either the double triple slit experiment or the triple double slit experiment, but we should not forget the double single slit experiment.

The Planck Length is also an indication that our reality is pixelated and not smooth.
True, that is a hypothesis that it could mean. Something is observing us in controlling the trajectory, or it could mean that we are emanating ionic force with our eyes, and with our concentration, and that we can change the direction of ionic movement with a thought think about that.

no matter how often i watch this experiment i will always be stunned be the result. this is so awesome. also it shows that all choices that we make is one out of endless possibilities.
So, if you did the experiment with 3 slits, would the outer 2 slits cancel the inner slit and make just 2 bright bands? The wave pattern should cancel the inner line.
Watching this video alone in the middle of the night makes me think someone or something is going to abduct me when im asleep.
I’ve watched numerous videos about this experiment but most creators don’t explain the process and the results in a way that those without a degree in physics would comprehend. However, you’ve done a great job of doing what others have been incapable of doing successfully! I was trying to explain the Double Slit experiment to my friend who isn’t a student of physics as I am, and I couldn’t figure out how not to over complicate it and sound like a condescending jerk. Then I found your video which did a wonderful job of demonstrating and visualizing the experiment in plain language and with plain references to common everyday things!
I am now a subscriber and I look forward to watching your other videos!
Thank you for your kind words!
Could the speed of light limit be the result of the “clock speed” of the simulation for updating the position of particles in addition to determining their observed state?
I am a programmer and I thought about the idea, that the world might be programmed a lot. From this perspective the idea, that light behaves like a function whenever not observed closely seems like a typical optimisation. Why simulate a myriad of photons, when you really only need a macroscopic light/shadow texture.
I have many ideas about time, but it is very hard to order them. Time goes slower in proximity to large masses and obviously where there is a large mass there is a lot of matter and where there is a lot of matter a lot is happening and where a lot is happening a lot has to be computed - so it makes sense that the program needs a lot of time to calculate each frame in these regions and therefore time in these regions runs slower. This is obviously not a commonly used programming strategy since in basically all programs time is a global variable and not depending on space or anything else. Time also goes slower when moving very fast and this makes sense since an object that moves very fast potentially experiences a lot of different things in a very short time, which again is computationally expensive.
In the end I really can't wrap my head around all this though. It is an intriguing idea at the least and I'd really like to explore these topics deeper and gain a real understanding of it all.
I don't really understand how you want to connect the clock speed and the speed of light though?! It could definitely have something to do with it, but why would these two things be dependent?
@@Rollmops94So, dark matter and dark energy are remote servers then. And what we see is the interface 😊.

“Wave particle duality…”
“I SHOOT MY PHOTONS INTO THEEEEEEEEEE SLIIIIIIITS” 🎶
I don't think we live in "simulation", but i do think that universe we live in, works similar to a computer program.
it's a FACT that by observing something, you are altering it. or to say it in a different form "you can't observe something without altering it". It's very simple concept, in order to observe something, you must interfere. for example if you are looking at something, then particles interact with your eyes, which is interference.
same happens with cameras. if camera sensor is able to see whatever it is looking at, then that object is also able to detect presence of the camera sensor.
more fascinating thing for me, is fabric of space. we know it exists, because that's what causes gravity. gravity is 4-dimensional. when on earth (or other planets), if you drop something, it will fall towards the core, but in space, if you place something on fabric of space, it will bend inwards, making a 4-dimensaionl "bowl" and things will fall into it.
if you'd be able to get in center of a planet, you'd be in 0g.
so if fabric of space exists, then it means that fabric of space MUST have shape and size. what is that shape and size?
I think it's a cube, because that would make most logical sense and also refers to the theory that it's all a big "simulation".
another interesting thing, is that there MUST be tiniest particles that cannot be destroyed, which act as 1s and 0s, as in binary. if particle exists, it's a 1, if no particle, it's a 0. which means that everything in universe is basically just data, that can be created, copied and/or deleted.
another thing about fabric of space, if it exists (which it does), then it must have particles, but what does it consist of? normal matter don't collide with it, is that what scientists call "dark matter"?
but yes, i too think that universe is more like a computer than "natural".
Nothing can be created nor deleted, everything in this world has always existed
To be Honest the Title of the video is quite misleading
Yep. The only support for it in the video is “some people think this means the universe is programmed”. Not exactly “proof of a simulation”.
I mean, what does "observing" mean? Of course if we point a laser or however these particles were measured at them it will be impacted by our measuring device. The real question is, is the same effect happening when we simply observe it with our eyes (which i know is probably impossible since we are talking about very small scales). But it is more than logic to me that if you point a measuring device at a particle it is affected by it. I mean you can only measure things if you "touch" them in some way be it physically or with other methods...I mean i could be totally wrong here, but this is my view on it.
I remember now that i have seen a program about this many years ago. It blew my mind then, and still does now! Wow! Thank you for this, it's amazing to get yout mind blown every now and then ❤😮
This is the first time I’m hearing about this experiment. And my mind is literally thinking this has to be a conspiracy. But how do you explain the electrons behaving that way!? 😂
Like she stated, no one can explain electrons or photons behaving that way. It’s a mystery. Quantum Entanglement is another great mystery. Look it up.
The apparatus to detect which slit the particle went through, was flawed.
@@robertwilliamson922 Sure, it's a mystery in the same way "why does gravity work" or "why do virtual particles exist". Those phenomena sort've just exist. There's a property of the universe. There isn't a reason, it just sort've does.
@@tristanmisjanot a good analogy. Those things do exist and we know they exist. None of that changes based on if someone’s watching or not.
@@victorfernandes83 Yup, and neither Quantum Entanglement nor Wave-particle Duality are affected by whether or not someone is watching.
Observations that are passive in nature would not alter the nature of the particle being observed. Active observation implies an illumination of the particle utilizing some manner of energy, and observing the result. To passively observe the particle, you must know something of the basic nature of the particle, otherwise the particle goes undetected. To actively observe particle, you must also know the basic nature of the particle, and how it will react to the energy imposed on it, or it will again go unnoticed, or display a result which doesn’t make sense. This also applies in our efforts in attempting to understand and observe dark matter and dark energy.

@@johndenugent4185 ofc, it would be weird to not feel superior over dumb people
I thought electrons were fired at the double slit (or crystals that accomplish the same diffraction phenomenon) and what was crazy was that the electrons (which were particles) actually created the interference pattern. And furthermore, firing one electron at a time, instead of one photon at a time, still created the interference pattern. An illustration of this was done awhile back with a cartoon character named Dr. Quantum: th-cam.com/video/NvzSLByrw4Q/w-d-xo.html. I might be totally wrong here, but I thought the it was electrons that went back to behaving like particles when they were being observed, not photons. Regardless, this video is great for visualizing the interference pattern created by waves and particles. I enjoy Cindy Pom's Newsthink videos!
They have now observed wave-particle duality at the scale of multiple atoms. All matter has this property apparently. Insane to think about.
Everything is waves. Classical Newtonian physics is just happening at a scale where the boundaries of those waves are very well defined relative to their scale so they can just be thought of as masses.
When I was at university (back in the Stone Age!) the experiment was presented as done with electrons. I recall this, because (I guess I was a bit behind the other students), I first had to have the nature of a ''gun'' that shoots SINGLE electrons explained to me. The set up was as beyond my understanding as the incredible results of the experiment. To answer your question, the results of the Double Slit experiment have been replicated with photons, electrons, neutrons, atoms and even large molecules! Incredible.
In Quatum physics, "being observed" is NOT sinonimous to conscious observation. Its more related to measurement. Specially the physical interference that this observation causes on the particles.
Impressive, it usually takes longer than this to prove I'm dumb.
I guess the tree that fell in the woods that no one was there to see, was never heard and may not have even happened.
Aliens: guys they're onto us

The conscious observer doesn't collapse the wavefunction - collapsed wavefunctions cause consciousness.
Observing photon means that a force is getting deflected or getting bounced back off photon. Since photon is relatively sooooooo small than the reflective object you're using.... something must be going on
How does measuring device work?? How does it measure? What it measures? Doesn’t see photon moving ? It takes a picture?
When. measuring device is attempting to determine through which slit a photon is passing.
1. **Scattering:** One method involves scattering the photon off a target or a material near one of the slits. When the photon interacts with the material, it changes direction (scatters), and this altered trajectory can be detected by the measuring device. However, the act of scattering alters the photon's state, making it difficult to maintain the interference pattern.
2. **Absorption and Re-emission:** Another approach is absorption. The measuring device might absorb the photon momentarily and then re-emit it. During this absorption, information about the photon's path is gained. However, due to the uncertainty principle, this absorption process inevitably imparts uncertainty to the photon's momentum, affecting the interference pattern.
Okay hear me out. What if I flew a Minecraft flying machine through a double slit of bedrock would this work the same?
I know your comment was a joke but I answered it anyway😂
Macroscopic objects can also experience diffraction, but the slit would have to be ridiculously small because big objects have a tiny tiny wavelength, and the slit needs to be smaller than that wavelength

“What does it all mean Basil?”
I could relate this completely to Krishna and arjuna in Baghavath Geetha . Where Krishna asks arjuna to think in his perspective which alters reality as perspective changes
How do we actually "observe" the particles? Maybe our way of "observing" the particles changes their state.
Define "observe". To "observe" a photon, that photon must hit something, either your retina or a photosensitive plate (like a film). When the photon hits the retina or the "film", it disappears. You can't "observe" a photon without interacting with it. What you are seeing IS the photon, you can't magically "see" a photon.
The fact that they made a proton gun with single fire is crazy enough
It doesn’t change when it’s ‘observed’
It ‘changes’ whenever it’s forced into an interaction, that forces an outcome to the probabilistic wave function
