"The good news is it is alive. The bad news it is dead. It is both alive and dead. Also which one you see depends on your point of observation." This is truly mind blowing though studying quantum particle physics. I do not believe in far out quantum theory like time dilation and matter being in a time field where if physical phenomena can escape space scenarios they still cannot escape time scenarios. I believe time is a perception of the mind. Likewise I do not believe schrodinger's cat represents the true reality of alternate dimensions and universes existing at the same time and being applied to black hole theory etc. There is a practicality to it. It is mind blowing how Schrodinger's cat is applied in a practical sense through observation of sub atomic particles. Is the cat in the box both alive and dead at the same time? When unobserved the cat in the box acts as both. However when the box is lifted the particles behave one way or another depending on how observed. Eventually this became Heisenberg's uncertainty principle. Practicality would tell us both cannot be real but both are subatomic particles behave like particles or waves depending on how observed. In a way this is how all things are in your sleep there is no gravity or physical boundaries but when you awake they quite clearly exist. Will we ever know the true reason for how particles exist as both at the same time but one or another when observed? Maybe never. It is a great mystery but still the more we understand this the more we understand the true atomic model and obviously if a formula was cracked for why it may take us light years beyond our current understand of atomic processes and fission and fusion and anti matter etc. Even though we know so much already there is so much we don't know.
Not true cat actually makes sound from time to time so if you woudl stand close to the box you would know wheter the cat is dead or alive, no superposition.
I agree because if there were a split universe where as to humans are highly advanced (time travel, different dimension travel etc). , wouldn't they have came by now, and or try and communicate or something like take our resources or give us knowledge.
DEV time travel isn't necessarily inter-dimensional, though. they might have traveled back to early settlements of their dimension but not ours. it's also possible that in our dimension we'll never discover time travel. who knows!

+blikjekattenvoer Except there is actually zero tangible evidence for a higher diety. And scientists believe in things after scientific experiment have proven them to be in existence. So don't try and make it a 50/50 situation. It's not.
@Moonlight phan - That's the point Shrodinger was making, that Quantum mechanics suggests the cat is alive and dead at the same time, and that is absurd. It suggests there isn't just a single reality. Young's slits shows a similar thing in a different way. Experiements overwhelmingly support that this model is right.
Since I came across this concept this is the second video I am watching. And I am 100% sure that i dont have watch anymore for better understanding. A good explanation love. Kudos. GOD bless you
Schrodinger did not invent the cat story to show how weird quantum mechanics is, but to show how ridiculous the Copenhagen interpretation, in which the observer plays a critical role, is. He did not believe the cat would be in a superposition of dead and alive, he considered it nonsense and so do I. The later idea that the Universe splits in two at every quantum event that could have two outcomes is even more nonsensical.

Thank you! The logic of Schrodinger's Cat just wasn't clicking for me even after watching 2 other videos I still couldn't quite get it. After watching yours I am pretty sure I got it! You explained it so clearly to someone without any previous study! Thanks a bunch!
This implies we are living multiple lives, potentially ad infinitum, in parallel dimensions, without even being aware of one another, yet independently making choices and consistently creating new universes of possibility.
Jane Roberts discusses this possibility in many different ways, and levels of reality in SETH SPEAKS and also THE SETH MATERIAL. If you're curious, do look for it.
Flip a coin, I call heads, you call tails. It's tails. But actually it was heads, but because you looked at it and called tails, split into a different timeline, therefore you cheated, it was heads in the original timeline!
The theory never mentions going back in time, in the sense that one could look at something that happened and then make a choice in the past... nor it mentions that our choosing will forcefully change the result of the timeline we are set in to our advantage. Nor it mentions skipping between timelines. I don't think you have te right approach to it..
but you can argue that whatever timeline you're currently in happened because of the events or lack of events that had occurred which "caused" the timeline that happened to occur.
what a load of crap. I like how no one mentions that the idea of big bang contradicts this quantum crap. How did the Universe come about through and create its structure if the first particles couldn't have a defined position unless it was observed.
what caused the collapse onto a state if only way the collapse can happen if it was observed. This is why Einstein was right when he said you are telling me the moon is not there unless I observe it?
Silly person. Every time you die you enter into the existence of the closest dimension. You fell off your bike as a young child, and yet, you only scraped your knee... but everything, somehow, changed. You almost got side swiped by that truck that friday night, on the way home. Made you shake, and be thankful you didn't take that last drink. Yet, everything became different... Every time something changes that you just can't put your finger on, oh all the kids are calling it the mandela effect.. but. it's just you migrating closer and closer to knowing if that cat is alive or not. One meaningless death, at a time.
Isn't there an inherent problem with this experiment, in that, the cat itself holds consciousness and therefore is observing inside the box, -- observing it's own decay up until the point of death at which stage it's no longer conscious? So, if a consciousness observing the event ensures an outcome, then there was only ever one outcome possible because the cat is conscious. Or am I misunderstanding something here?
Exactly! The experiment would’ve made much more sense if the object in the box was incapable of observation. Perhaps it’s because people used to think animals were not truly conscious.
Great video! However, I am still confused as to why observation collapses multiple superpositions of a particle into one position. I understand how the observer effect can alter the position of particles and waves, but what I don't understand is why it would matter if something is being observed in terms of whether it is in a superposition or in a single position.
Surely that means that’s there’s a universe in which someone has figured out how to travel between universes, and decided to come to ours to tell us about it
Just because it can be several different things doesnt mean that it is all these things at once. It's either dead or alive, it's not both dead and alive until looked upon.
In the original experiment (theorized), the Geiger counter tripped a switch that broke a flask of Hydrogen Cyanide which killed the cat - not the tiny amount of radiation.
Altair Ibn La-Ahad I think the video said radiation kills the cat because the person who made the video didn't do their research. She doesn't point out that Schrödinger's point was that the dead cat/alive cat at the same time scenario was absurd and obviously not true, showing us that the contemporary view of quantum mechanics was flawed.
There was a man that had a pet cat/dog, so smart, that when he said to the animal: Do you wanna play fetch or not? The cat/dog played fetch or not at the same time.
Subscribed! I just watched many other videos on this subject that left me scratching my head. This one help me understand the absurdity that is quantum mechanics. Thank you!
Actually, what almost everyone seems to have forgotten is that A. 'Schrodinger'S cat' was Schrodinger ironic statement concerning the theory of superposition. B. The point of the whole cat being ' both death and alive' was his way of asking the question 'Where lies the border between quantum reality and Macro reality? He chose the unpredictability of Uranium's decay as the representation of quantum reality. And the cat presenting the macro reality . The cat being 'both death and alive' pointing to the absurdity of superposition.
What people fail to mention when talking about quantum superposition using Schrodinger's Cat is the difference between a classical bit of information (like a computer bit being on or off) and a quantum bit of information (a qubit). Both bits produce one of two outcomes when queried (measured), but a classical bit has only one measurement possible while a qubit can be measured in many different ways (infinitely many, actually), each with two possible outcomes. For example, when you pass an electron through an inhomogeneous magnetic field, the electron is either deflected towards the North magnetic pole ("up") or towards the South magnetic pole ("down"). You can orient the N-S magnetic field in any direction you like and the electrons will still give one of those two outcomes, so electron spin is a qubit with two outcomes of spin "up" and spin "down" relative the the N-S magnetic field. Now suppose you pass electrons through a N-S magnetic field oriented vertically and then send those that were deflected "up" (literally up in this case) to a N-S magnetic field oriented horizontally. What do you expect to find? Well since the electrons have vertical spin up and spin is a vector (picture an arrow pointing upward here), then you probably expect the electron to pass straight through the horizontal magnetic field, i.e., they won't be deflected left or right at all ("up" or "down" relative to the horizontal N-S field). That's because the electron's spin vector (arrow) points up which means it doesn't point side-to-side (left of right) at all, so your horizontal spin measurement of a vertical spin up electron should seemingly yield a result of zero horizontal spin. But what you find instead is that 50% of the vertical spin up electrons are deflected left ("up" towards North pole) and 50% are deflected right ("down" towards South pole). True, 50% left plus 50% right *averages* to zero, but that's not what you expect from the measurement of a vector quantity in ordinary classical mechanics. [Aside: Quantum mechanics gives the classically expected results on average over the discrete or quantum measurement outcomes.] This is quantum superposition, a vertical spin up electron is a quantum superposition of 50% horizontal spin left and 50% horizontal spin right and we write that as |V+> = |H+> + |H-> (divided by root 2 for normalization, but I don't need that to make my point). The point here is the horizontal spin measurement of the quantum state |V+> produces each of its two "up"-"down" (left-right) results in 50-50 fashion. This is exactly what you hear people say about Schrodinger's Cat, i.e., you open the box and find the cat is dead with 50% probability or find the cat is alive with 50% probability. With that information alone, Schrodinger's Cat could be a classical bit or a qubit. If Schrodinger's Cat is a qubit, then there must be a measurement of the cat-box system like the vertical spin measurement of the state |V+> that produces |V+>, i.e., |H+> + |H->, with 100% certainty. We know the measurement "open the box" producing "Live Cat"-"Dead Cat" results in 50-50 fashion is analogous to the horizontal spin measurement of |V+>, so what is the measurement of the cat-box system giving |Live Cat> + |Dead Cat> with 100% certainty in analogy with the vertical spin measurement of the state |V+> that produces |V+> with 100% certainty? And what does its outcome mean physically? If you can't articulate that measurement and outcome of the cat-box system, and every possible measurement between that measurement and the "open the box" measurement, then the cat-box system is just a classical bit ... like flipping a coin to find heads or tails. No quantum superposition there 🙂 To read more about the quantum information approach to entanglement for the "general reader," see "Einstein's Entanglement: Bell Inequalities, Relativity, and the Qubit" due out in June 2024 with Oxford UP.
Erwin Schrödinger was driving home one night when he was pulled over by the police. The officer asked him to step out of the car while he searched the vehicle. After a while, he went to the back of the car and opened the trunk. In that moment, the officer said, "hey do you know that you've got a dead cat in here?" To which Schrödinger replies, "Well I do now".
@@arcaipekyun4232 would it though? i could watch a murderer kill a man and would he stop? would he continue if he didn't see me? of course. of course he would. just because you can observe things most likely doesn't mean it'll change. you didn't observe it but you will still see that a murder happened in the news.
Fred The Skrub reference is not right. Thing is if there were no observers in your example, then you wouldn’t know what has really happened. As soon as you observe, you will learn it. But if you were there watching it, then you would directly learn it, so there wouldn’t be that situation where you didn’t know what happened. When you talk about schrödinger’s cat and that observing changes something, you mean that immediately when you observe that, for you that very thing will go from uncertainty to certainty. Same goes for the murderer. If there are no observers, then it would be an uncertainty, and what has happened would only be certain when someone goes to the crime scene. But if you were watching it, then the uncertainty would not happen, and the situation would be clear. You understood this wrong. Observer changes the event is not that observer changing something from happening to not. It is that with an observer there are no uncertainty.
Success in understanding something can never rely solely upon common sense, intuition, mathematics, or upon every known physical law. Some questions which cannot be asked, formulated, or even concieved may well still have insurmountable barriers. They may always.
but then you still wont know if the cat is alive or dead until you look at the camera and maybe in another universe the camera doesnt show anything there cant just be two super positions there are infinite ones and that is probably why black holes were created. too many super positions so there is super position that stops super positions. i dont know what im trying to say any more....
No, a passive observation has zero impact on the experiment. In this case, there is no requirement other than passive observation, to determine if the cat is alive or dead. However, at a quantum level, one must interfere with whatever is to be measured in order to gauge a difference. A dark room, you're blindfolded. Reach out to see if there is a glass of water in front of you. You feel the table, interfering with it as you do, and suddenly you feel your hand knock over the glass of water. By sheer observation, you destroyed the coherency of the glass of water, but you did discover that it was there. You have to alter the outcome, at a quantum level, just to know if the experiment was viable. But a cat in a box has no such inclusions. A better test would be to put 2 cats in a box.
Particles can only travel at the speed of light, so they cant be everywhere at once. A particle can naturally decay without being measured, but it cannot be in two states at the same time. At any given instant in time, the particle can only be in one definite state, either as a particle or a decay product. The process of decay involves the particle transitioning from one state to another over a certain period of time, during which it cannot be in both states simultaneously. The experiment was only conceptual thought experiment, not to be taken literally.
Hello, I am undecided as to whether I subscribe to the "super state" theory detailed here, or to the theory that there's no breaking in the natural behavior of particles, but rather a breaking in our observation and data. To illustrate, I could play devils advocate and say that the cat in the box is already dead or alive, and the only reason I do not know is because I have not observed it. Anyway the video was great, thank you. As always science and theory will have to suffice until understanding takes hold. Here's hoping it happens in my lifetime, I'm ever curious.
slight problem - the cat is a living entity with consciousness and has its own observations that are fracturing realities and collapsing wave functions (superPositions). So why would the cat care if a human was observing the box? theres a 50/50 chance the human might not make the observation from the cats perspective. what about micro-organisms inside the box? they are generating their own consciousness and effecting reality, They must be considered too. This sounds more like a god analogy. Erwin Schrodinger was very religious and i think this is about a creator. God is watching at all times, if you are good and follow his word you will receive the positive outcome etc. God = energy field.
Theycallmeroman wasn't trying to sound enlightened or knowledgeable. I asked valid questions. I'm guessing you like schrodingers theory but don't like the fact that he believes in a creator?
@Theycallmeroman: And yet, it wasn't nearly as hilarious as your "attempt" at understanding him. And so all the thanks goes to you, my friend. Perhaps they should call you "inane".
+Melissa Clark Great film. Imagine it happening in real life. I think the way they all freaked out is well justified. I would sure as hell freak tf out.
Starting at timestamp~ 0:45 is the state the particle finally chooses to go into after measurement (after superposition collapses) one of the previous states measured at about timestamp 0:38 ?
Is "observing" the cat limited to opening the box any physically seeing it or does that include listening to any sounds that might be coming from the box (which would suggest life)?
All this time I was trying to comprehend the theory of Schrodinger's Cat. Only after I watched this video I finally realized that I was supposed to assume the cat as a *particle* instead of a *literal* one.
That's the problem with many simplified presentations of quantum mechanics. Many such explanations use analogies that demonstrate the ideas but obscure some of the not-so-unimportant subtleties. Even worse, they often fail to explain that these analogies should not be taken literally. Usually, this leads to extremely vague and sometimes misleading explanations. I've found that only after studying the subject seriously from a rigorous, mathematical framework do I understand it. Looking back now on these simplified explanations, it seems hopeless for anyone without a proper education in physics to understand what the hell these people are talking about.
As an aside, the whole Schrodinger cat thing is a TERRIBLE way to introduce the concepts of quantum mechanics to someone who actually seeks to understand it.
The whole thing with the cat is an analogy: of course the cat doesn't consider itself to be both living and dead. The point of it is to illustrate the basic concept of quantum superposition. Also I find it quite misleading to say that, if a particle is in a superposition of states, that it is literally in both states at the same time, e.g. the cat is both alive and dead. You can never observe the particle (cat) to be in more than one state at a time; the act of measurement collapses the superposition into a single state, with a certain probability of collapsing to each state depending on the exact form of the superposition state. I think it's better, though perhaps no less misleading, to say that the particle (cat) is not in any observable states (is neither alive nor dead).
I finally understand the meaning of Schrödinger's cat thought experiment. Schrödinger, a real scientist, developed this thought experiment and published it as a way to send a message to students of physics, which is this: You, as students of physics, should know more than anyone that we live in a physical universe that is explained by various theories, including the Newton’s scientific theories of motion and also, more recently, the theories of quantum mechanics, which is a theory that correctly models how physical things that are relatively tiny, physically function. All of the physical laws of physics always apply without exception, including all of those that have already been developed and published. Sure, there are imaginary numbers in math and conscious beings with minds have imaginations capable of imagining that a cat could exist in two different forms in a closed box without a physical conscious observer observing it, but that does not mean that anything in the real, physical universe exists in two forms at the same time and then collapses into one form or the other whenever there is a conscious observing it. Spacetime exists. Energy exists. Physical forces exist. Atoms and molecules exist. Electrons and photons exist. Their various characteristics and functions could be explained, measured, and scientific theories, which include mathematical models, could be developed to explain particular aspects of the physical universe. There are imaginary numbers in math. Humans have imaginations. This does not mean that what is imaginary exists in real spacetime. He highlighted this fact to physicists by discussing objects in his imaginary thought experiment that are much, much larger than the objects that the physics of quantum mechanics explains the function of. Quantum mechanics is the explanation for how certain aspects of things on the scale of electrons and photons function. It does not explain or provide mathematical models of the behavior of cats. We should all know or at least be able to imagine that a cat would jump out of the goddamn box like a bat out of hell 📦 if it were placed in one with a vial full of some glowy stuff or even water. It would not wait for a conscious observer in order to collapse into one physical state or the other. It wouldn’t collapse. It would probably fight its way out of the box. It, like the trillions of trillions of electrons that are part of its body, always exists in only one real physical existence in only one, real physical form, which a conscious observer could study or measure if one chose to do so, but whether or not one observes the cat does not change its existence or its properties, including its extinct to want to get out of that goddamn box like a bat out of hell, which it would probably do, regardless of whether anyone or anything was outside of the box-and if it didn’t get out and you were a conscious observer around the box to see it and chose to not help the cat get out, you would at least hear it trying to get out. Quantum mechanics does not explain the behavior of cats or how to breed and raise cats. It explains something else. Mathematical models are just that and math is perfect. There are imaginary numbers and imaginations, but physical things don’t exist in two physical forms simultaneously, regardless of whether or not there is a conscious observer or whether or not the mathematical equations appear to you to suggest that they do. If you measure it, you will see that it exists in one form. It doesn’t choose to collapse into one of two forms when someone is watching. Electrons and photons don’t choose to do anything, first of all. Newton’s equations still apply for what they explain and you could measure a cat’s speed or velocity during a particular frame of time and use Newton’s equations to determine its acceleration, or use your imagination to approximate it without it physically occurring in the real triple-dimensional space, single-dimensional time. You could also study the psychology or behavior of cats or the various coats or sizes of cats. There are sound theories to explain all of those things. They’re all physical phenomenon in the physical universe. Quantum mechanics describes certain aspects of something in particular, like all scientific theories do, and it’s not the behavior of cats, but just like cats don’t collapse into one form or the other just because there is an observer, neither does anything else. Quantum mechanics doesn’t explain the behavior or states of cats, but a cat was used in this thought experiment to make a point. There is such a thing as imaginary numbers in math-and imaginary possibilities that exist in conscious minds, which only human beings and computer software are capable of possessing. You can only measure something if you observe it. Things don’t exist in more than two physical forms and collapse into one or the other just because there is a conscious observer watching it then or taking measurements. Oh, and by the way, software developers could give A.I. software-hardware beings an imagination 😉
They haven't, there be no point...As he explained, we cannot see this other Universe. Our selves in that Universe shall, we however, like they could never know that the other result happened. He never killed any cats, nor did he ever attempt it. He was simply stating a fact and logic because Cats have the strange ability to survive what other animals cannot.
The point I am yet to see covered or read about which seems to be missing is that, does the cat not observe its own state? The cat has a consciousness whilst alive which essentially acts as the uncovering of the box, making the box itself redundant. Can this be true of a single particle? Can the particle itself be experiencing its environment, or is the particle different to the cat in this regard?
ok, first of all, you stated the experiment wrong. the cat is not killed by radiation, the radiation triggers the release of a poison, which in turn kills the cat. furthermore, you completely failed (or actually didnt even try) to resolve the paradox. obviously the cat is NOT dead and alive while the lid is closed and its state is certainly NOT determined the moment you open the lid and that is NOT what this thought experiment is telling us. the very simple explanation for this "mind-boggling" paradox is that "observation" in this context has nothing to do with US (as sentient and intelligent beings) observing it. it simply means that the particle interacts with another particle and thus has to collapse into a certain state (because the outcome of the interaction is dependent on the state of the particles at the time of the interaction). these interactions happen all the time and as soon as a certain outcome is reached, the fate of the cat is sealed, whether we open the lid or not (well, technically we can save the cat by removing it from the poisonous environment fast enough, but thats not the point) also, i am pretty sure, that this multiverse-theory is BS. i might be wrong about this (i am not a theoretical physicist^^), but I always thought that the state of the particle at the time of the interaction actually IS determined; we are just not able to predict the state of the particle, because it is impossible (for us) to gather all the data needed, so we have to rely on probabilities (until we can observe a certain state). now, if this assumption is correct, there are not multiple possible states, so there is no reason for the universe to split.
THANK YOU. It's nice to see someone who has actually bothered to read up on this instead of spewing bullshit like in most of the other comments (and indeed the common misinterpretation in the video). The entire point of the experiment is to say "and obviously that's absurd and untrue on a macroscopic level" essentially. Quote from Schrödinger: "It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naively accepting as valid a "blurred model" for representing reality. In itself, it would not embody anything unclear or contradictory. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks."
Conner Mcmahan What? Saying that things that aren't the video *aren't in the video* is stating a fact, and as the video doesn't actually contain a) a full and correct version of the experiment and b) the purpose of the experiment, those aren't strawmen either. Amusingly, calling either of our responses a strawman is a misrepresentation you're ragging on, thus making your statement a strawman. Good job!
Conner Mcmahan No, the second sentence is blatantly wrong. The purpose is to point out a flaw in the Copenhagen interpretation, not to point out an aspect of quantum physics. His point was that the cat is EITHER dead OR alive, never both, so the model doesn't extend to a macroscopic level, which among other things questions when collapse occurs. The video suggests that the experiment examines quirks and doesn't mention Schrödinger's intentions and conclusions. It's misleading.
schrödinger: Mr Veterinarian, how is my cat doing?

"The good news is it is alive. The bad news it is dead. It is both alive and dead. Also which one you see depends on your point of observation." This is truly mind blowing though studying quantum particle physics. I do not believe in far out quantum theory like time dilation and matter being in a time field where if physical phenomena can escape space scenarios they still cannot escape time scenarios. I believe time is a perception of the mind. Likewise I do not believe schrodinger's cat represents the true reality of alternate dimensions and universes existing at the same time and being applied to black hole theory etc. There is a practicality to it. It is mind blowing how Schrodinger's cat is applied in a practical sense through observation of sub atomic particles. Is the cat in the box both alive and dead at the same time? When unobserved the cat in the box acts as both. However when the box is lifted the particles behave one way or another depending on how observed. Eventually this became Heisenberg's uncertainty principle. Practicality would tell us both cannot be real but both are subatomic particles behave like particles or waves depending on how observed. In a way this is how all things are in your sleep there is no gravity or physical boundaries but when you awake they quite clearly exist. Will we ever know the true reason for how particles exist as both at the same time but one or another when observed? Maybe never. It is a great mystery but still the more we understand this the more we understand the true atomic model and obviously if a formula was cracked for why it may take us light years beyond our current understand of atomic processes and fission and fusion and anti matter etc. Even though we know so much already there is so much we don't know.

It's only a representation of how extremely small stuff behaves in the lab. Much smaller than a cat, he just explains it with a cat so we can visualize it. lol
+blikjekattenvoer
Except there is actually zero tangible evidence for a higher diety. And scientists believe in things after scientific experiment have proven them to be in existence. So don't try and make it a 50/50 situation. It's not.
@Moonlight phan - That's the point Shrodinger was making, that Quantum mechanics suggests the cat is alive and dead at the same time, and that is absurd.
It suggests there isn't just a single reality. Young's slits shows a similar thing in a different way. Experiements overwhelmingly support that this model is right.
Since I came across this concept this is the second video I am watching. And I am 100% sure that i dont have watch anymore for better understanding. A good explanation love. Kudos. GOD bless you
Schrodinger did not invent the cat story to show how weird quantum mechanics is, but to show how ridiculous the Copenhagen interpretation, in which the observer plays a critical role, is. He did not believe the cat would be in a superposition of dead and alive, he considered it nonsense and so do I. The later idea that the Universe splits in two at every quantum event that could have two outcomes is even more nonsensical.
But how did the Sliders on that show slide into all those other worlds?
Mike Albrow so how do you explain the double slit experiment ?

OH FUCK NO.....that leaves nowhere for sensational fucktards that do not realize when college is over
This was the video that actually explained this in a way I could understand - finally!! ✨
Just shake the box!
To shake the box would lead to an outcome which itself would be necessarily observable, therefore...particle collapse.
Freedom's Tavern it's a load of bullshit, if a tree falls and no one's around to hear it guess what, IT FELL AND IT MADE A SOUND we live in reality not fairy land
+wildboy789789 Or...it (the tree) fell and it made a vibration (or sound wave). Our ears translate the vibration into "sound". So...if there is nor physical ear to interpret the vibration...did it?
Freedom's Tavern the point is, it didn't act any differently because no one was there to witness it, the tree and vibrations acted normally either way
@ wildboy789789 your just a typical dumbass lol
Thank you! The logic of Schrodinger's Cat just wasn't clicking for me even after watching 2 other videos I still couldn't quite get it. After watching yours I am pretty sure I got it! You explained it so clearly to someone without any previous study! Thanks a bunch!
This implies we are living multiple lives, potentially ad infinitum, in parallel dimensions, without even being aware of one another, yet independently making choices and consistently creating new universes of possibility.
Jane Roberts discusses this possibility in many different ways, and levels of reality in SETH SPEAKS and also THE SETH MATERIAL. If you're curious, do look for it.
Very good explanation
+djjayrex thank you! :)
+LondonCityGirl what brought me here is Rick and Morty, series 2, Episode 1 shows this theory. Only shown in America though.

Watched the whole episode right now cuz a you! Thanks! Who knows what I woulda done in that time if it wasn't for...
wheres the lazy pavlov?
I’ve watched many videos on Schrodinger’s Cat and this one explained it my untrained mind the best. Thank you!
Flip a coin, I call heads, you call tails. It's tails. But actually it was heads, but because you looked at it and called tails, split into a different timeline, therefore you cheated, it was heads in the original timeline!
The theory never mentions going back in time, in the sense that one could look at something that happened and then make a choice in the past... nor it mentions that our choosing will forcefully change the result of the timeline we are set in to our advantage. Nor it mentions skipping between timelines. I don't think you have te right approach to it..
but you can argue that whatever timeline you're currently in happened because of the events or lack of events that had occurred which "caused" the timeline that happened to occur.
what a load of crap. I like how no one mentions that the idea of big bang contradicts this quantum crap. How did the Universe come about through and create its structure if the first particles couldn't have a defined position unless it was observed.
or maybe we only see one outcome, because only one happened? And maybe this theory is total bullshit? HowBowDah?
what caused the collapse onto a state if only way the collapse can happen if it was observed. This is why Einstein was right when he said you are telling me the moon is not there unless I observe it?

so which other universe have you gone to? xD.... btw. i had front row seat on the goku-jiren fight. it was intense.
Silly person. Every time you die you enter into the existence of the closest dimension. You fell off your bike as a young child, and yet, you only scraped your knee... but everything, somehow, changed. You almost got side swiped by that truck that friday night, on the way home. Made you shake, and be thankful you didn't take that last drink. Yet, everything became different...
Every time something changes that you just can't put your finger on, oh all the kids are calling it the mandela effect.. but. it's just you migrating closer and closer to knowing if that cat is alive or not. One meaningless death, at a time.
Isn't there an inherent problem with this experiment, in that, the cat itself holds consciousness and therefore is observing inside the box, -- observing it's own decay up until the point of death at which stage it's no longer conscious?
So, if a consciousness observing the event ensures an outcome, then there was only ever one outcome possible because the cat is conscious. Or am I misunderstanding something here?
Exactly! The experiment would’ve made much more sense if the object in the box was incapable of observation. Perhaps it’s because people used to think animals were not truly conscious.
Yah you are misunderstanding the idea of measurement.
Great video! However, I am still confused as to why observation collapses multiple superpositions of a particle into one position. I understand how the observer effect can alter the position of particles and waves, but what I don't understand is why it would matter if something is being observed in terms of whether it is in a superposition or in a single position.
Best explanation of Schrodinger's cat and its implications I have found.
Surely that means that’s there’s a universe in which someone has figured out how to travel between universes, and decided to come to ours to tell us about it
Box: meow
Schrodinger: ignore that
*So, If the Cat is Dead, then "Your Curiosity" has Killed the Cat.*
Get out.
Just because it can be several different things doesnt mean that it is all these things at once. It's either dead or alive, it's not both dead and alive until looked upon.
In the original experiment (theorized), the Geiger counter tripped a switch that broke a flask of Hydrogen Cyanide which killed the cat - not the tiny amount of radiation.
+netjunkie9 I'm glad that someone pointed this out, otherwise we've got some crazy radiation source here :')
netjunkie9 I think the vid said that the radiation killed the cat so it's simpler
Altair Ibn La-Ahad I think the video said radiation kills the cat because the person who made the video didn't do their research. She doesn't point out that Schrödinger's point was that the dead cat/alive cat at the same time scenario was absurd and obviously not true, showing us that the contemporary view of quantum mechanics was flawed.
Yes but a lot of these explanation leave that out
Thank you. Much easier to understand than the TED explanation.
There was a man that had a pet cat/dog, so smart, that when he said to the animal: Do you wanna play fetch or not?
The cat/dog played fetch or not at the same time.

Actually, what almost everyone seems to have forgotten is that A. 'Schrodinger'S cat' was Schrodinger ironic statement concerning the theory of superposition. B. The point of the whole cat being ' both death and alive' was his way of asking the question 'Where lies the border between quantum reality and Macro reality? He chose the unpredictability of Uranium's decay as the representation of quantum reality. And the cat presenting the macro reality . The cat being 'both death and alive' pointing to the absurdity of superposition.

Why exactly?
Finally a video that actually made this make sense
thank you, you explained this very clearly. this is seriously crazy stuff
What people fail to mention when talking about quantum superposition using Schrodinger's Cat is the difference between a classical bit of information (like a computer bit being on or off) and a quantum bit of information (a qubit). Both bits produce one of two outcomes when queried (measured), but a classical bit has only one measurement possible while a qubit can be measured in many different ways (infinitely many, actually), each with two possible outcomes.
For example, when you pass an electron through an inhomogeneous magnetic field, the electron is either deflected towards the North magnetic pole ("up") or towards the South magnetic pole ("down"). You can orient the N-S magnetic field in any direction you like and the electrons will still give one of those two outcomes, so electron spin is a qubit with two outcomes of spin "up" and spin "down" relative the the N-S magnetic field. Now suppose you pass electrons through a N-S magnetic field oriented vertically and then send those that were deflected "up" (literally up in this case) to a N-S magnetic field oriented horizontally. What do you expect to find?
Well since the electrons have vertical spin up and spin is a vector (picture an arrow pointing upward here), then you probably expect the electron to pass straight through the horizontal magnetic field, i.e., they won't be deflected left or right at all ("up" or "down" relative to the horizontal N-S field). That's because the electron's spin vector (arrow) points up which means it doesn't point side-to-side (left of right) at all, so your horizontal spin measurement of a vertical spin up electron should seemingly yield a result of zero horizontal spin. But what you find instead is that 50% of the vertical spin up electrons are deflected left ("up" towards North pole) and 50% are deflected right ("down" towards South pole). True, 50% left plus 50% right *averages* to zero, but that's not what you expect from the measurement of a vector quantity in ordinary classical mechanics. [Aside: Quantum mechanics gives the classically expected results on average over the discrete or quantum measurement outcomes.] This is quantum superposition, a vertical spin up electron is a quantum superposition of 50% horizontal spin left and 50% horizontal spin right and we write that as |V+> = |H+> + |H-> (divided by root 2 for normalization, but I don't need that to make my point).
The point here is the horizontal spin measurement of the quantum state |V+> produces each of its two "up"-"down" (left-right) results in 50-50 fashion. This is exactly what you hear people say about Schrodinger's Cat, i.e., you open the box and find the cat is dead with 50% probability or find the cat is alive with 50% probability. With that information alone, Schrodinger's Cat could be a classical bit or a qubit. If Schrodinger's Cat is a qubit, then there must be a measurement of the cat-box system like the vertical spin measurement of the state |V+> that produces |V+>, i.e., |H+> + |H->, with 100% certainty. We know the measurement "open the box" producing "Live Cat"-"Dead Cat" results in 50-50 fashion is analogous to the horizontal spin measurement of |V+>, so what is the measurement of the cat-box system giving |Live Cat> + |Dead Cat> with 100% certainty in analogy with the vertical spin measurement of the state |V+> that produces |V+> with 100% certainty? And what does its outcome mean physically? If you can't articulate that measurement and outcome of the cat-box system, and every possible measurement between that measurement and the "open the box" measurement, then the cat-box system is just a classical bit ... like flipping a coin to find heads or tails. No quantum superposition there 🙂

So since I'm here in my room with no one observing me am I in a super state? Am I everywhere?
What I thought, too
No, because you are observing yourself by being consciously aware of your own being and surroundings, thus preventing a superstate from occurring.
Only if you are smoking a joint
Way more satisfying than any other videos over this theory
Schrödinger's smiley:
: ) :
Erwin Schrödinger was driving home one night when he was pulled over by the police. The officer asked him to step out of the car while he searched the vehicle. After a while, he went to the back of the car and opened the trunk. In that moment, the officer said, "hey do you know that you've got a dead cat in here?" To which Schrödinger replies, "Well I do now".
Great explanation. In another universe it was absolutely dreadful. Oh well, good thing we aren't there ;)

"Been there-it sucks"
Great video. Easy to understand.
Could there be a universe where the cat puts Schrodinger in a box?

Lmfao
Brilliant video. I have just subscribed to your channel. Keep up the good work.
in my universe we call this "Cat's Shrodinger", it's about a Shrodinger in a box, meow.
Schrodinger's cat walks into a bar. And then it doesn't
Why can’t you just get a glass box?
you would be observing the cat
No, a glass box is a fish tank, and only a blindingly slow and retarded pet fish would think of such things.
Doran Krotan observing would affect the result of the experiment
@@arcaipekyun4232 would it though? i could watch a murderer kill a man and would he stop? would he continue if he didn't see me? of course. of course he would. just because you can observe things most likely doesn't mean it'll change. you didn't observe it but you will still see that a murder happened in the news.
Fred The Skrub reference is not right. Thing is if there were no observers in your example, then you wouldn’t know what has really happened. As soon as you observe, you will learn it. But if you were there watching it, then you would directly learn it, so there wouldn’t be that situation where you didn’t know what happened. When you talk about schrödinger’s cat and that observing changes something, you mean that immediately when you observe that, for you that very thing will go from uncertainty to certainty. Same goes for the murderer. If there are no observers, then it would be an uncertainty, and what has happened would only be certain when someone goes to the crime scene. But if you were watching it, then the uncertainty would not happen, and the situation would be clear. You understood this wrong. Observer changes the event is not that observer changing something from happening to not. It is that with an observer there are no uncertainty.
thank you for your easy to understand explanation
did anyone else look this up after watching the film "coherence"?

Big Bang theory
Best explanation yet. Thanks.
the biggest use of this theory is seen in dark season 3 by seeing that u correct understand it🤗😁😅
Cat walks into the bar..
..and doesn't
just so you know if you try this the cat will probably be dead
Success in understanding something can never rely
solely upon common sense, intuition, mathematics, or upon every known physical law.
Some questions which cannot be asked, formulated, or even concieved may well still have insurmountable barriers. They may always.
Put a camera on the box and the Universe will not split. 😊
but then you still wont know if the cat is alive or dead until you look at the camera and maybe in another universe the camera doesnt show anything there cant just be two super positions there are infinite ones and that is probably why black holes were created. too many super positions so there is super position that stops super positions. i dont know what im trying to say any more....
nope, cause now it has split, one where there is no camera put on the box
No, a passive observation has zero impact on the experiment. In this case, there is no requirement other than passive observation, to determine if the cat is alive or dead. However, at a quantum level, one must interfere with whatever is to be measured in order to gauge a difference.
A dark room, you're blindfolded. Reach out to see if there is a glass of water in front of you. You feel the table, interfering with it as you do, and suddenly you feel your hand knock over the glass of water. By sheer observation, you destroyed the coherency of the glass of water, but you did discover that it was there.
You have to alter the outcome, at a quantum level, just to know if the experiment was viable.
But a cat in a box has no such inclusions.
A better test would be to put 2 cats in a box.
Everybody gangster till the cat starts meowing
I usually take this as the poorest theory I've ever heard
Thanks, London City Girl, that was a fantastic breakdown.
So I am rich, handsome, and famous in another world. But my states collapsed into reality and it is my observer's fault :D
Particles can only travel at the speed of light, so they cant be everywhere at once. A particle can naturally decay without being measured, but it cannot be in two states at the same time. At any given instant in time, the particle can only be in one definite state, either as a particle or a decay product. The process of decay involves the particle transitioning from one state to another over a certain period of time, during which it cannot be in both states simultaneously. The experiment was only conceptual thought experiment, not to be taken literally.
"There is a world where man never made it to the moon" its like me saying there is a world where the earth is flat.
Couple layers of irony here
Hello, I am undecided as to whether I subscribe to the "super state" theory detailed here, or to the theory that there's no breaking in the natural behavior of particles, but rather a breaking in our observation and data.
To illustrate, I could play devils advocate and say that the cat in the box is already dead or alive, and the only reason I do not know is because I have not observed it.
Anyway the video was great, thank you. As always science and theory will have to suffice until understanding takes hold. Here's hoping it happens in my lifetime, I'm ever curious.
slight problem - the cat is a living entity with consciousness and has its own observations that are fracturing realities and collapsing wave functions (superPositions). So why would the cat care if a human was observing the box? theres a 50/50 chance the human might not make the observation from the cats perspective. what about micro-organisms inside the box? they are generating their own consciousness and effecting reality, They must be considered too. This sounds more like a god analogy. Erwin Schrodinger was very religious and i think this is about a creator. God is watching at all times, if you are good and follow his word you will receive the positive outcome etc. God = energy field.
Your "attempt" at trying to sound enlightened and knowledgeable made me laugh out loud quite heartily. Thank you.
Theycallmeroman wasn't trying to sound enlightened or knowledgeable. I asked valid questions. I'm guessing you like schrodingers theory but don't like the fact that he believes in a creator?
Exactly what I was thinking.
I was totally onboard with this comment until I saw god in it
@Theycallmeroman: And yet, it wasn't nearly as hilarious as your "attempt" at understanding him. And so all the thanks goes to you, my friend. Perhaps they should call you "inane".

Starting at timestamp~ 0:45 is the state the particle finally chooses to go into after measurement (after superposition collapses) one of the previous states measured at about timestamp 0:38 ?

Is "observing" the cat limited to opening the box any physically seeing it or does that include listening to any sounds that might be coming from the box (which would suggest life)?

All this time I was trying to comprehend the theory of Schrodinger's Cat. Only after I watched this video I finally realized that I was supposed to assume the cat as a *particle* instead of a *literal* one.
That's the problem with many simplified presentations of quantum mechanics. Many such explanations use analogies that demonstrate the ideas but obscure some of the not-so-unimportant subtleties. Even worse, they often fail to explain that these analogies should not be taken literally. Usually, this leads to extremely vague and sometimes misleading explanations. I've found that only after studying the subject seriously from a rigorous, mathematical framework do I understand it. Looking back now on these simplified explanations, it seems hopeless for anyone without a proper education in physics to understand what the hell these people are talking about.
As an aside, the whole Schrodinger cat thing is a TERRIBLE way to introduce the concepts of quantum mechanics to someone who actually seeks to understand it.
If you replace the cat with a human, is he still both dead and alive? The human can look for himself, but why can't a cat?
Replace it with anything you want. The point is, is that Superposition is nonsense.
The whole thing with the cat is an analogy: of course the cat doesn't consider itself to be both living and dead. The point of it is to illustrate the basic concept of quantum superposition. Also I find it quite misleading to say that, if a particle is in a superposition of states, that it is literally in both states at the same time, e.g. the cat is both alive and dead. You can never observe the particle (cat) to be in more than one state at a time; the act of measurement collapses the superposition into a single state, with a certain probability of collapsing to each state depending on the exact form of the superposition state. I think it's better, though perhaps no less misleading, to say that the particle (cat) is not in any observable states (is neither alive nor dead).
Reminded me of the book Dark matter

whos here after hearing this from Dark?
Very good explanation👍👍👍👍👍👍👍 thanks!!!
Hit or Miss? I gue-
Shut up. It's both now.
I finally understand the meaning of Schrödinger's cat thought experiment. Schrödinger, a real scientist, developed this thought experiment and published it as a way to send a message to students of physics, which is this: You, as students of physics, should know more than anyone that we live in a physical universe that is explained by various theories, including the Newton’s scientific theories of motion and also, more recently, the theories of quantum mechanics, which is a theory that correctly models how physical things that are relatively tiny, physically function. All of the physical laws of physics always apply without exception, including all of those that have already been developed and published. Sure, there are imaginary numbers in math and conscious beings with minds have imaginations capable of imagining that a cat could exist in two different forms in a closed box without a physical conscious observer observing it, but that does not mean that anything in the real, physical universe exists in two forms at the same time and then collapses into one form or the other whenever there is a conscious observing it. Spacetime exists. Energy exists. Physical forces exist. Atoms and molecules exist. Electrons and photons exist. Their various characteristics and functions could be explained, measured, and scientific theories, which include mathematical models, could be developed to explain particular aspects of the physical universe. There are imaginary numbers in math. Humans have imaginations. This does not mean that what is imaginary exists in real spacetime.
He highlighted this fact to physicists by discussing objects in his imaginary thought experiment that are much, much larger than the objects that the physics of quantum mechanics explains the function of. Quantum mechanics is the explanation for how certain aspects of things on the scale of electrons and photons function. It does not explain or provide mathematical models of the behavior of cats.
We should all know or at least be able to imagine that a cat would jump out of the goddamn box like a bat out of hell 📦 if it were placed in one with a vial full of some glowy stuff or even water. It would not wait for a conscious observer in order to collapse into one physical state or the other. It wouldn’t collapse. It would probably fight its way out of the box. It, like the trillions of trillions of electrons that are part of its body, always exists in only one real physical existence in only one, real physical form, which a conscious observer could study or measure if one chose to do so, but whether or not one observes the cat does not change its existence or its properties, including its extinct to want to get out of that goddamn box like a bat out of hell, which it would probably do, regardless of whether anyone or anything was outside of the box-and if it didn’t get out and you were a conscious observer around the box to see it and chose to not help the cat get out, you would at least hear it trying to get out. Quantum mechanics does not explain the behavior of cats or how to breed and raise cats. It explains something else.
Mathematical models are just that and math is perfect. There are imaginary numbers and imaginations, but physical things don’t exist in two physical forms simultaneously, regardless of whether or not there is a conscious observer or whether or not the mathematical equations appear to you to suggest that they do. If you measure it, you will see that it exists in one form. It doesn’t choose to collapse into one of two forms when someone is watching. Electrons and photons don’t choose to do anything, first of all.
Newton’s equations still apply for what they explain and you could measure a cat’s speed or velocity during a particular frame of time and use Newton’s equations to determine its acceleration, or use your imagination to approximate it without it physically occurring in the real triple-dimensional space, single-dimensional time. You could also study the psychology or behavior of cats or the various coats or sizes of cats. There are sound theories to explain all of those things. They’re all physical phenomenon in the physical universe. Quantum mechanics describes certain aspects of something in particular, like all scientific theories do, and it’s not the behavior of cats, but just like cats don’t collapse into one form or the other just because there is an observer, neither does anything else. Quantum mechanics doesn’t explain the behavior or states of cats, but a cat was used in this thought experiment to make a point.
There is such a thing as imaginary numbers in math-and imaginary possibilities that exist in conscious minds, which only human beings and computer software are capable of possessing. You can only measure something if you observe it. Things don’t exist in more than two physical forms and collapse into one or the other just because there is a conscious observer watching it then or taking measurements.
Oh, and by the way, software developers could give A.I. software-hardware beings an imagination 😉
Why would nobody actually do the shcrodinger cat experiment???
because it would potentially kill cats half of the time :O
Because we can't observe the experiment so we cant do it
They haven't, there be no point...As he explained, we cannot see this other Universe. Our selves in that Universe shall, we however, like they could never know that the other result happened. He never killed any cats, nor did he ever attempt it. He was simply stating a fact and logic because Cats have the strange ability to survive what other animals cannot.
d.i.d iza dodo do eng were ridz ya? DEScryptives box out in en v lope?
The point I am yet to see covered or read about which seems to be missing is that, does the cat not observe its own state? The cat has a consciousness whilst alive which essentially acts as the uncovering of the box, making the box itself redundant. Can this be true of a single particle? Can the particle itself be experiencing its environment, or is the particle different to the cat in this regard?
ok, first of all, you stated the experiment wrong. the cat is not killed
by radiation, the radiation triggers the release of a poison, which in
turn kills the cat.
furthermore, you completely failed (or actually didnt even try) to resolve the paradox.
obviously the cat is NOT dead and alive while the lid is closed and its state is certainly NOT determined the moment you open the lid and that is NOT what this thought experiment is telling us.
the very simple explanation for this "mind-boggling" paradox is that "observation" in this context has nothing to do with US (as sentient and intelligent beings) observing it. it simply means that the particle interacts with another particle and thus has to collapse into a certain state (because the outcome of the interaction is dependent on the state of the particles at the time of the interaction). these interactions happen all the time and as soon as a certain outcome is reached, the fate of the cat is sealed, whether we open the lid or not (well, technically we can save the cat by removing it from the poisonous environment fast enough, but thats not the point)
also, i am pretty sure, that this multiverse-theory is BS. i might be wrong about this (i am not a theoretical physicist^^), but I always thought that the state of the particle at the time of the interaction actually IS determined; we are just not able to predict the state of the particle, because it is impossible (for us) to gather all the data needed, so we have to rely on probabilities (until we can observe a certain state). now, if this assumption is correct, there are not multiple possible states, so there is no reason for the universe to split.
THANK YOU. It's nice to see someone who has actually bothered to read up on this instead of spewing bullshit like in most of the other comments (and indeed the common misinterpretation in the video). The entire point of the experiment is to say "and obviously that's absurd and untrue on a macroscopic level" essentially.
Quote from Schrödinger:
"It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naively accepting as valid a "blurred model" for representing reality. In itself, it would not embody anything unclear or contradictory. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks."
You literally just strawmanned the video lmfao
Conner Mcmahan What? Saying that things that aren't the video *aren't in the video* is stating a fact, and as the video doesn't actually contain a) a full and correct version of the experiment and b) the purpose of the experiment, those aren't strawmen either. Amusingly, calling either of our responses a strawman is a misrepresentation you're ragging on, thus making your statement a strawman. Good job!
All strawmen are facts. And the purpose of the experiment is in the second sentence of the video
Conner Mcmahan No, the second sentence is blatantly wrong. The purpose is to point out a flaw in the Copenhagen interpretation, not to point out an aspect of quantum physics. His point was that the cat is EITHER dead OR alive, never both, so the model doesn't extend to a macroscopic level, which among other things questions when collapse occurs. The video suggests that the experiment examines quirks and doesn't mention Schrödinger's intentions and conclusions. It's misleading.
