      "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.

    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.

      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..

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.

    @wmstuckey 7 месяцев назад

    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 🙂

    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?

      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.

    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.

      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.

      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).

    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.

One that I'm hung up on is the theory of Schrodinger's Cat , this very theory, and the multiple universe theory that is born of it. If this theory holds true, is there a possible path where the universe might never die out? Is there a chance that there is - in an alternate universe - a species so advanced that it might reach beyond the confines of it's own universe to manipulate others? Would that not have a rebounding effect on itself? What would happen? Is there already a theory derived of these ponderings? Am I over thinking things? Am I just totally lost to the concept here? Seriously, watching these videos have left me awed and confused.

    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.

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 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.

    Quantum Mechanics proves that Reality does and does not exist at the same time, proves that the duality of Reality, that the two qualities of a singularity, are, of course, are not born of two different realities. The two qualities represent a Single Reality, the two qualities being distinctly different each from the other. The two cats in Schrödinger’s Box are the two, dual, qualities of a single Cat which may either dead or alive, are both dead and alive at the same time. The dead cat and the live cat is actually a single cat that is both dead and alive at the same time. The two cats represent represents a Reality that has no relative, no numerical value, that has a numerical value of Zero-0, Nada, The Nothingness, that existed prior to the moment of the creation of the first singularity of Zero-0 to make the quantum leap, be converted into a Singularity of One-1 Into the Reality of First Cause, an affect, became the direct cause of a System of Chaos which made manifest Reality of the Heavens and the Earth, the Universe, the Reality of Everything that exists in the material sense of the word.

      So how can a Reality both exist and not exist at the same time? The Reality that does not exist has no relative numerical value, has a numerical value of zero-0, Nothing, is the primordial, the primary, is a Superior Reality, with the Reality of First Cause, the Singularity having a numerical value of One-1 being the secondary Singularity, the Reality that does exist.

    • @92587wayne
      @92587wayne 3 года назад

      The primary, primordial Singularity is a single Reality that does and does not exist, primordially speaking does not exist, has no mass, is not measurable as to location and momentum in Space and Time which did not exist simply because it was motionless.. The Heavens and the Earth, the Universe, the reality of everything was motionless, nothing having angular momentum, the velocity of speed and direction. Motion existing as a vibration, as an innate inner oscillation within each singularity of Zero-0. The first, the Reality of First Cause being a Singularity of Zero-0 that had the possibility of being converted into a second Singularity of One-1. A singularity of zero-0 and a singularity of One-1 being the same Singularity, identical, yet each is distinctly different from the other. Zero-0 being representative of Nothing and the Singularity of One-1 being uncaused, being a creation, the Reality of First Cause, the direct cause of a system of chaos that made manifest Reality of the Heavens and the Earth, the Universe, the Reality of Everything that exists in the material sense of the
      Word. Reality itself being born of Nothingness. As a Singularity of Zero-0 issued forth from the Event Horizon it was converted into the second of two singularities, the Reality of First Cause. 0\1

    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?

      +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.

    maybe a stupid question but why not use a glass box or another material that is transparent?

    The answer to this scientific theory is that scientists have to study spirituality to get the answer. Atoms and subatomic particles move based on *thought and emotion* being vibrated from the person, meaning God and the human mind is the same thing. This is also known as the law of attraction, meaning a person attracting a red car to themselves through this process. The atoms don't come to the person on their own, it's the person causing all this to move. So to make it sound more easier: The type of thought & emotion + The vibration + the conscious and subconscious mind = The type of universe that is being created.
