+Ultimate Gamer Actually, when I first heard about this theory years ago I was astonished and went very excited to tell a friend. After I told the whole thing she just answered me ''well, has anyone already attempted to do the experiment?'' Yeah, I know...
If only Jonas and Martha were in superposition states in the ending. Or if they are entangled in the quantum level than at least one of them should have existed in the ending
They both were in a state of entanglement (loop of two parallel worlds) until the last episode. However, in the last episode they destroyed the knot (loop) and erased the existence of entanglement.
Have to disagree with this video's claim that entanglement will someday allow us to send information or teleport someone instantaneously across the universe. The results of positions of entangled particles are indeed always opposite; however, they are also always randomly opposite. So this will never allow us to send deliberate patterns of information (coordinated 1's and 0's) because all the 1's and 0's will be random and meaningless, even if the pairs are always opposite.
You could resolve this paradox by saying that this is technically not delivering information faster than the speed of light, because once we measure one of the cats state, we already know the state of the other one. So this isn't violating Einstein's rule of no information is able to deliver information faster than light.
Removing the “both dead” and “both alive” possibilities seemed kind of arbitrary. That must be the part that is too difficult for us mere mortals to understand.
It has to do with conservation of momentum. If the system has a total spin of 1, you cannot end up with 2 particles with spin of 1 (alive cat) or 2 with 0 spin (dead cat).
From what I understood in a Veritasium video, since the total angular momentum in a universe must stay constant, if one particle spins up the other must spin down. Whether the cat is dead or alive represents the up or down spin of a particle. th-cam.com/video/ZuvK-od647c/w-d-xo.html @Safwan Baksh

@@stevengreen4253 you seem to know what you're talking about so I'm going to ask you this question. Haha it's your punishment for being smart. Anyway. I'm a non physics trained just enjoyer of the topic. I conceptualize entanglement using a wishbone example. If you break the bone with a friend and hide the piece in your hand, you each have a 50/50 chance of having either piece (superposition?) If you go to the moon and look at your piece first, you put yours in position and consequently theirs too?
I've been trying for years to wrap my head around quantum physics (like many people) and this video did a really good job of explaining it. So as I understand it now, quantum physics is something that occurs at an atomic level but at a macro level that we would observe in everyday life...
Maybe like in a simulated game or a cartoon. The 2d or 3D characters have to follow the rules of space or physical interactions as ordained by the artist existing in a higher dimension(probably two dimensions higher). But suddenly the artist decides on a whim to make an object appear by painting or coding it. Then the characters, initially shocked that the appearing object has breached the rules, start realising that what they thought to be the rules was not law but rather illusory that had ways around them. They then start to find hacks; enlightenment, quantum computing, teleportation...
Chike Ezebilo I think the speed limit is only limited by perception, perhaps there is no speed limit but in order to perceive anything the mind has to draw the line and choose. for example, if you want to watch a snail race an asteroid, you have to make the decision to watch only one of them, as the asteroid would get so far ahead it can no longer be seen, or the snail so far behind.
mesure the total spin of two particles and when you then mesure their individual spins it must add up to the total. However the two particles spins are individual random but will always come out to add up to the corect total. So for instance, if two particles together have 0 spin then one particle must have spin 1 and the other spin -1 (this might corospond to spinning clockwise or counter clockwise). The total must be 0 and 1 + (-1) =0. But its random which will have spin 1 and which will have spin -1. So until you measure one of them each particle could be either 1 or -1 but once you mesure one of them you now know that it is 1 and the other is -1 or the reverse. This is true no matter how far apart they were seperated.
TheZzpop that's what I don't get. They both had to choose on or the other right when the box was closed to balance out so why do we say that the information is being transferred at the next measurement. We are measuring something that was decided when the lid was closed. Please help me understand this.
Blake Young Well, it actually isn't decided when the lid is being closed, that is a slight misconception that arises from the analogy in the video. In quantum mechanics the actual "collapse of the wave function" as it is called, happens when the particle is OBSERVED. What this means is that the particle is in two (or more) states at the same time until a measurement is made.
The experiment is usually conducted with a poisonous radioactive isotope that has a 50% chance of decaying and killing the cat inside the box over the course of an hour. I'm assuming the narrator was attempting to simplify the experiment, but the substitute explosion does tend to confuse things.

There's a very interesting, somewhat new theory about ER=EPR. The information travels through a wormholes, and from this emerges a physical reason for the quantization of space-time. If I can find the World Science Festival episode with it, I'll link it.

Schrödinger's cat has always fascinated me, so thank you for this video, which made me think about this interpretation again. Firstly, the experiment to have connected particles at opposite ends of the universe has not been done. Secondly, the experiment described here has presumably only been done on earth or in the space station - we haven't travelled any further as far as I know. The video fails to explain how the linked particles are created. The idea of superposition is a concept derived from probability, not an actual state. In the macroscopic world, we do not always 'know' where something is: it may be at one point or it might be at another, but we do not assume that it is everywhere at once. We only know, where it is when we interact with the light rays bouncing off it or the reaction with some other sensor. If the object is moving, the object is in a slightly different position from the observed light rays, because of the tiny delay in the light or heat or radiation reaching our sensors. We are happy to agree in the macroscopic world, that we might not know where something is, but that someone else might. In the case of Schrödinger's cat, it is certain the cat does not think it is in superposition. It 'knows' whether it is alive. In the same way a particle knows, where it is, because its behaviour is determined by the interaction with all the other particles in the environment or the universe. We know where we are, because we know which other particles are affecting us. The concept of spin is very simplistic in the video, suggesting that you can match opposite rotations in a 2D fashion as if there was an orbital plane. I have read that electron spin about the nucleus is three dimensional, so I cannot understand how you can create 'opposite' spins. If someone does know, how to create opposite spin, I would be delighted to receive a response to this comment. If you don't know where a particle is until you observe it, how do you know that you are observing the same particle at the later stage of the experiment. How can you mark an electron, so that you know which of the pair you are observing? If the two particles are in separate boxes and this is how you tell them apart, how do you know that the opposite spins are not contingent on the properties of the container? If spin changes on a incredibly tiny time frame, it is possible that multiple longer term observations could still fail to spot the condition, where both particles are spinning in the same direction : is, both cats are alive, or both cats are dead. If the science of quantum entanglement has been done in a vacuum, then this may explain part of the difficulty of relating quantum mechanics to classical mechanics. The results of the experiment may tell us only about how particles relate in our experiment and not about how they react under other real-world conditions. This is a good video for explaining how physicists have tried to make sense of the world.
It is an old saying” if you can not explain it to a child then you do not know it “ , that is what this video is like a very simple explanation that everybody understands. Thanks
Though I haven't started learning any of the quantum mechanics equations or anything I find it very easy to understand and interpret most of the ideas of quantum mechanics
lol, allow me to suggest you take an MBTI test (free online everywhere). If my 'theory' is correct, you are an INTJ. I understand quantum theory or so I think I grasp the concepts and this drives every math person in my life insane because I have always been challenged by Math unless a sales discount was involved and yet, I can speak Quantum leap and I never once watched that old tv show. Seriously, you may lead with Ni dom in the Carl Jungian information processing cognitive function stacks. Have you read Nietzsche?
The question is: How did you know that the cat is in a superposition of 'alive' and 'dead' instead of one fixed state before you observe it. This is the core difference between classic physics and quantum mechanics, and have been often ignored in this type of videos. I knew there are a few VERY COMPLECTED experiments involving measuring polarity/spin states of photons with 50% chance of this and 50% chance of that, but these experiments are often tooooooo tricky and tooooo complicated to explain, and definitely need to repeat and testify by different labs. I am not convinced with the 'fact' of quantum entanglements. I agree the idea of 'superposition' can help us to explain and predict many things, but we can't measure those properties doesn't necessarily mean uncertainty is an inherent property of the quantum world. These two theory are fundamentally contradictory and only one of them is true. I am on the side of Einstein.
They don't need to communicate to one another because they were always spinning in opposite directions from the moment they became "entangled". We just didn'y know in which direction, but as soon as we measure, we now the direction the spin of both. In a way, both particles have the information of itself and the one entabgled to it, that's wh we dont need the to communicate. The thing is, we can't know the spins of the particles until we measure them, and when we measure them, we know the spins of both so they're no longer entangled. There's nothing we can do to pass information from one to the other, I dont see how teleportation is possible of faster than light communication.
You are correct, there is no FTL information flow here. The idea that "the particles are carrying the information" is not correct either, though. One can devise more complex scenarios (that's what the Bell inequalities are about) in which such a classical assumption leads to the wrong predictions. The simple fact is that quantum fields do not behave like classical fields and whenever we try to force such a model on them nature tells us that we are wrong. One has to make peace with that.
Quantum entanglement pretty much proves monistic idealism, an existential theory that states consciousness is the primary "stuff" of reality and that matter and energy are just a projection. Please read The Self-Aware Universe by Amit Goswami if you would like to explore this concept.
No it does not. What you, and probably this guy you're talking about, do is mixing observation and consciousness. In physics an observation doesn't need a conscious mind. It is more of an interaction between particles. So your theory is just like any other claim of this sort, interesting to think about but not proven by science in any way.
Corentin Vacheret I wouldn't even call it interesting... Seems incredibly narcissistic and pretentious to believe that humans being conscious is what created matter or... a "projection" of matter... I mean really... how arrogant do you need to be to claim that humans are sooo special their minds are what created the cosmos or at least the matter within it.. It doesn't even make sense... modern humans have existed for 200,000 years and all hominids 6-7 million... The universe 13.7 billion... So unless he plans on claiming that humans consciousness is what created humans and the universe (which equally makes no sense) then it doesn't make sense.
Uhh I understood uncertainty of position and momentum and Schrödinger's cat thought experiment. Thank you TedEd. And those people who think our force of observation collapses nature to one of either probabilities is not for the cat. It's just a thought experiment to help understand the movement and behaviour of electrons around the nucleus.
Schrödinger wrote:[1][8] One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The first atomic decay would have poisoned it. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts. 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 naïvely 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.
Again plot twist, if we are the cat some one is observing us and some one is observing our observer as well and so on unless we reach a cosmic observer, which is observing all the cosmos, sitting outside the cosmos, so the cosmic observer has set up rules for this simulation which we are in and programmed every thing from paths of stars to laws of physics to coding found in our DNA, in simplified language this proves existence of GOD.
If someone see my comment please answer me. So here's the thing, I would do the same thing but instead of using cats I used coins. I put them in a different boxes and shake it. My question is; 1. Is it still super position if I shake the box? 2. - Will it always be the two outcomes? (other is head and the other is tails and vice versa) - If not, why is that? 3. How can we REALLY determine if the experiment is in a Super Position? Example; how did the scientist make the two subatomic particle Super Position? How did they set it up like that? They need to not observe the object to do it but by doing the experiment they are observing the object or rather the subatomic particle. It's just my thought I really want to become a great scientist one day and by doing so I need your help
Actually the question u asked was really nice one...but as per my knowledge any process can be said to be in superposition state if it is affected by only one kind of force and should independent from other system forces....example for an electron the electrostatic force of attraction plays a role...but in case of your example the coin it is in a field of earth which is already interacting with Sun and moon...ther fore there are many deviations..
pauli's exclusion principle states that if one of the two electrons in an orbital have up spin then the other can only have down spin (opposite spins). Similiarly, if one cat is alive the other has to be dead.

There's a very interesting, somewhat new theory about ER=EPR. The information travels through a wormholes, and from this emerges a physical reason for the quantization of space-time. If I can find the World Science Festival episode with it, I'll link it.
If memory serves, it's based on Hologram theory. I think the part I'm thinking of is about 2/3 of the way into the talk.

Now I am in a superposition of understanding quantum mechanics and not understanding it
Appreciate the cool animation they did for the video.... Great concepts made understanding with simple and funny graphics....
* Dark final season is released *
Hmmm, I wonder why TH-cam is recommending me this
Schrödinger's cat has always fascinated me, so thank you for this video, which made me think about this interpretation again.
Firstly, the experiment to have connected particles at opposite ends of the universe has not been done. Secondly, the experiment described here has presumably only been done on earth or in the space station - we haven't travelled any further as far as I know.
The video fails to explain how the linked particles are created.
The idea of superposition is a concept derived from probability, not an actual state. In the macroscopic world, we do not always 'know' where something is: it may be at one point or it might be at another, but we do not assume that it is everywhere at once. We only know, where it is when we interact with the light rays bouncing off it or the reaction with some other sensor. If the object is moving, the object is in a slightly different position from the observed light rays, because of the tiny delay in the light or heat or radiation reaching our sensors. We are happy to agree in the macroscopic world, that we might not know where something is, but that someone else might. In the case of Schrödinger's cat, it is certain the cat does not think it is in superposition. It 'knows' whether it is alive. In the same way a particle knows, where it is, because its behaviour is determined by the interaction with all the other particles in the environment or the universe. We know where we are, because we know which other particles are affecting us.
The concept of spin is very simplistic in the video, suggesting that you can match opposite rotations in a 2D fashion as if there was an orbital plane. I have read that electron spin about the nucleus is three dimensional, so I cannot understand how you can create 'opposite' spins. If someone does know, how to create opposite spin, I would be delighted to receive a response to this comment.
If you don't know where a particle is until you observe it, how do you know that you are observing the same particle at the later stage of the experiment. How can you mark an electron, so that you know which of the pair you are observing? If the two particles are in separate boxes and this is how you tell them apart, how do you know that the opposite spins are not contingent on the properties of the container? If spin changes on a incredibly tiny time frame, it is possible that multiple longer term observations could still fail to spot the condition, where both particles are spinning in the same direction : is, both cats are alive, or both cats are dead.
If the science of quantum entanglement has been done in a vacuum, then this may explain part of the difficulty of relating quantum mechanics to classical mechanics. The results of the experiment may tell us only about how particles relate in our experiment and not about how they react under other real-world conditions.
This is a good video for explaining how physicists have tried to make sense of the world.
Beautiful
That little cat wink at the end near about killed me
It is an old saying” if you can not explain it to a child then you do not know it “ , that is what this video is like a very simple explanation that everybody understands. Thanks
Soooo I just tried this experiment,and now my room is filled with smoke and cat guts...
Shouldn't have opened the box.
+Anthony Hayes lol 😂😂😂
Results pls both alive or dead

Haha Dark
Everybody at Schrödinger's funeral : Hmmm..
I watch these videos for sleep theyre mad relaxing
The method of explaining the topics is really very good. Some more videos regarding quantum physics will be really appreciated
Finished watching dark yesterday
TH-cam today:
Schrödinger's smile/frown for you - :(:
Schrödinger : there is no way you can tell that cat is alive or not until you open the box.
Cat : MEOW...
Schrödinger : ......
The pause before the cat wink in the ending though
"So is the cat alive?"
"Yes'nt"
Though I haven't started learning any of the quantum mechanics equations or anything I find it very easy to understand and interpret most of the ideas of quantum mechanics
lol, allow me to suggest you take an MBTI test (free online everywhere).
If my 'theory' is correct, you are an INTJ.
I understand quantum theory or so I think I grasp the concepts and this drives every math person in my life
insane because I have always been challenged by Math unless a sales discount was involved and yet,
I can speak Quantum leap and I never once watched that old tv show.
Seriously, you may lead with Ni dom in the Carl Jungian information processing cognitive function stacks.
Have you read Nietzsche?
Knowing that one day your cat will escape to a safer galaxy where there are no physicists and no boxes, fills you with determination.

Legends says cat is still waiting for some one to open that box.
You'll know the cat is alive when it starts to meow. 🤣
this is one of the highest quality vids from TEDed yet.
The question is: How did you know that the cat is in a superposition of 'alive' and 'dead' instead of one fixed state before you observe it. This is the core difference between classic physics and quantum mechanics, and have been often ignored in this type of videos. I knew there are a few VERY COMPLECTED experiments involving measuring polarity/spin states of photons with 50% chance of this and 50% chance of that, but these experiments are often tooooooo tricky and tooooo complicated to explain, and definitely need to repeat and testify by different labs. I am not convinced with the 'fact' of quantum entanglements.
I agree the idea of 'superposition' can help us to explain and predict many things, but we can't measure those properties doesn't necessarily mean uncertainty is an inherent property of the quantum world. These two theory are fundamentally contradictory and only one of them is true. I am on the side of Einstein.
I agree with you.
Alright so how do two entities become “entangled”?
Legendary Gattos exciting space using energy to create particles out of energy
Schrödinger : There is no way of knowing if the cat is dead or alive until you open the box
The cat : Meow
They don't need to communicate to one another because they were always spinning in opposite directions from the moment they became "entangled". We just didn'y know in which direction, but as soon as we measure, we now the direction the spin of both. In a way, both particles have the information of itself and the one entabgled to it, that's wh we dont need the to communicate.
The thing is, we can't know the spins of the particles until we measure them, and when we measure them, we know the spins of both so they're no longer entangled. There's nothing we can do to pass information from one to the other, I dont see how teleportation is possible of faster than light communication.
You are correct, there is no FTL information flow here. The idea that "the particles are carrying the information" is not correct either, though. One can devise more complex scenarios (that's what the Bell inequalities are about) in which such a classical assumption leads to the wrong predictions. The simple fact is that quantum fields do not behave like classical fields and whenever we try to force such a model on them nature tells us that we are wrong. One has to make peace with that.
Quantum entanglement pretty much proves monistic idealism, an existential theory that states consciousness is the primary "stuff" of reality and that matter and energy are just a projection. Please read The Self-Aware Universe by Amit Goswami if you would like to explore this concept.
Lol, someone has an elementary grasp of Quantum Mechanics... been watching too much Deepak Chopra have we?
This channel is about physics not philosophy
Gary Merchant I wouldn't call that philosophy... more like random guessing
No it does not. What you, and probably this guy you're talking about, do is mixing observation and consciousness. In physics an observation doesn't need a conscious mind. It is more of an interaction between particles. So your theory is just like any other claim of this sort, interesting to think about but not proven by science in any way.
Corentin Vacheret I wouldn't even call it interesting... Seems incredibly narcissistic and pretentious to believe that humans being conscious is what created matter or... a "projection" of matter... I mean really... how arrogant do you need to be to claim that humans are sooo special their minds are what created the cosmos or at least the matter within it..
It doesn't even make sense... modern humans have existed for 200,000 years and all hominids 6-7 million... The universe 13.7 billion...
So unless he plans on claiming that humans consciousness is what created humans and the universe (which equally makes no sense) then it doesn't make sense.
one day my cat will be free from physcist world and boxes ;-;
TH-cam why was this "entanglement" recommended to me? You know what I was searching for.
Uhh I understood uncertainty of position and momentum and Schrödinger's cat thought experiment. Thank you TedEd.
And those people who think our force of observation collapses nature to one of either probabilities is not for the cat. It's just a thought experiment to help understand the movement and behaviour of electrons around the nucleus.
Netflix dark brings me here.... Anyone else?
I know you are here because TH-cam recommended you after watching Dark S3
Schrödinger wrote:[1][8]
One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The first atomic decay would have poisoned it. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts.
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 naïvely 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.
And now this theory has received a Nobel prize after 8 years. Don’t know what the future holds for us humans?
Sounds like schrodenger started quantum mechnics as a joke then other scentists came and proved it
Antman has joined the chat.
Plot twist! We are the cats
No plot twist at all... this concept applies to everything in our lives: information only has a real value when measured.
Precisely!
Again plot twist, if we are the cat some one is observing us and some one is observing our observer as well and so on unless we reach a cosmic observer, which is observing all the cosmos, sitting outside the cosmos, so the cosmic observer has set up rules for this simulation which we are in and programmed every thing from paths of stars to laws of physics to coding found in our DNA, in simplified language this proves existence of GOD.
If someone see my comment please answer me.
So here's the thing, I would do the same thing but instead of using cats I used coins. I put them in a different boxes and shake it. My question is;
1. Is it still super position if I shake the box?
2. - Will it always be the two outcomes? (other is head and the other is tails and vice versa)
- If not, why is that?
3. How can we REALLY determine if the experiment is in a Super Position? Example; how did the scientist make the two subatomic particle Super Position? How did they set it up like that? They need to not observe the object to do it but by doing the experiment they are observing the object or rather the subatomic particle.
It's just my thought I really want to become a great scientist one day and by doing so I need your help
Actually the question u asked was really nice one...but as per my knowledge any process can be said to be in superposition state if it is affected by only one kind of force and should independent from other system forces....example for an electron the electrostatic force of attraction plays a role...but in case of your example the coin it is in a field of earth which is already interacting with Sun and moon...ther fore there are many deviations..
5:06 OMG SO CUTEEEE!!!
how is it possible to erase the both cats dead /alive possibility?
pauli's exclusion principle states that if one of the two electrons in an orbital have up spin then the other can only have down spin (opposite spins). Similiarly, if one cat is alive the other has to be dead.
Wouldn't the box also explode when the bomb does...and then we can know for sure whether the bomb exploded or not without opening the box
If u never open the box, the cat starves to death
I think YT recommends it to people after they watch videos about DARK lmao😂😂😂
