The Copenhagen interpretation of quantum mechanics tells us that observation collapses a probability wave into a single definitive outcome, but this isn’t the only interpretation of quantum mechanics. The many worlds theory proposes that the wavefunction never actually collapses. The observer simply follows one of those many possible paths into their present reality while all the other paths continue on independent of the observer. Each of these paths branches off into an entirely different reality. In this episode Matt discusses the details of the many worlds theory and why it’s not so far-fetched to think that our reality is simply one of an infinite number of realities existing within space time.

    @A Frustrated Gamer How does this explain the delayed choice quantum eraser experiment? The whole interference pattern changes just because we observed the photon. When the eraser is used the interference pattern appears again just because we would have no idea which photon went where. How does many world theory explain that? Copenhagen interpretation agrees straight with the experiments according to me

    That's actually a really good question, I think we assume infinite scenarios allowing for every case to happen, due to the definition of infinite. But then due to the nature of sub atomic particles - I'm sure it'd just be a matter of repeating the experiment? all universes would definitely get the same results we did Begs the question then do we have infinite universes were not every outcome is realised? That's my take anyway. Awesome question

Most of them usually devolve into something like "it's impossible to prove or disprove" which just pushes the issue beyond the realm of physics. Your response also implies free will by suggesting that there is another me who could make that decision. So in a world where I am screwing myself over infinitely many times by taking the more desirable route, and also being screwed over infinitely many times, I am simultaneously demonstrating my free will while also having my future determined due to my other-self's free will which leads to a paradox. Does free will work like a lottery where in any given situation only one of my infinite selves gets the honor?

    It's much more likely that we don't exist, than even one other of ourselves existing somewhere else or in any other time. Other universes having exact duplicates of us is a fantasy. All it would take is a few ppl dying a few generations ago, in that other universe or timeline, and there'd be practically a whole different population living there, than what we have here now. All the talk about unlimited versions of ourselves would be impossible in reality, Reality is not magic. But believing is magic, so if you believe it, it can be real to you and that is almost as good as true. True enough for us. Since it is of the highest unlikelihood that we would ever know for sure, then you're safe, and believing what you want is good for you. So live it up but stay safe, the doppelganger you save may be yourself!

It doesn't matter how incredibly small its probabilities are - if you give it an infinite number of occasions to happen, it will keep happening. Imagine the probability of your own existence, all things considered. It is astronomically small sure, but it's obviously not zero. When we cease to exist and our consciousness switches off, how long will it take for every single atom to be at the same exact place as they are right now? Probably googleplexes of years. But since it's possible, it's bound to happen again... an infinite number of times. Add infinite universes to that and nothing is impossible.

Nothing lasts forever, so an event or person that happens twice in a few trillion years may not get to happen again, we run out of time. Also, how could every single part of a thing be just right in every way, how could anything ever really happen again, if you think about it, nothing is exactly like anything else. That would be perfection. It's true that things have a randomness, but also it all has a cause and result. Sure, you can win twice at a casino, but that deals with a limited # of possibilities.

    Insane way to win the lottery: buy a ticket, plug the number into a computer that compares the winning number when it comes out, hook that up so it sets off a very powerful bomb if the numbers do not match, and then stand next to it during the drawing. From your point of view the bomb would never go off and you would win the lottery! or the bomb malfunctions somehow... but from our point of view you almost certainly die spectacularly. I'd prove it (to myself) by trying myself, but unfortunately I live in the universe where me not doing it was a far more likely way of continuing to observe the universe. :(

The reason why this is an important point is that the universe may have formed with an unimaginably immense multiverse simply because the physical properties of it cause such a thing to emerge.

    Regarding the issue of the lack of free will in the many worlds interpretation, I would argue that even in a purely random universe, one could argue that there is still no free will. Look at it this way: pure determinism offers us no choice/freedom. We are enslaved to the pre-determined physics of our particular timeline/world. But with pure randomness, we are still without free will as we are enslaved to the pure randomness of the physics of our universe. We would never argue that a game of Russian Roulette offers us the free will to choose the outcome, so why would physics be any different. If it's just the randomness of quantum mechanics that determines my "choices", how is that different from my choices being determined by the rolling of dice? Does anyone have an idea of a third option that could involve free will?

    Not really sure if this will help but this is the way I always thought of free will. My perspective is it really doesn't matter if we have it or not for a couple reasons. First is I think you will agree no matter what we believe about free will as humans we *feel* like we do have it. So that being the case we can assume that even if we don't have true free will we at the very least have the illusion of free will. Now here is the most important question for this line of thinking, can you think of what if any differences would be between what the experience of true free will vs the illusion would be? Idk about you but if when i really take a close look at it I can't tell much difference at all between what we assume is true free will and the potential fake version I know we all have.

    This is extremely well put. Some system produces our experience of mind (it's mostly the brain, but the following holds even if it's magicy spirity stuff). The most elementary components of that system are either deterministic or random. Are either of those consistent with free will? I would argue that both can be, but only for the right definition of "free will". The problem with the whole free will debate is that the concept of free will is hopelessly poorly defined.

    to answer this we probably have to get a precise definition of free will, or even life, maybe. In this series and science we talk a lot about 'observers' which is as close as we scientifically come to defining what you look for, perhaps. observer to choice is already a leap of faith and has to be defined properly, but i don't know just an opinion.

    +InMaTeofDeath Oh of course, I'm very much with you. Either way, it does FEEL like we have free will in some form. Though, I will say that if we really look at it, in psychological terms, the existence of free will is still a messy concept due to the fact that our unconscious/subconscious minds are the unseen driving factor behind everything we think and do. And we don't exactly have conscious control over our unconscious minds. In this way, this could be said to be a psychological representation of how the laws of physics allow us the illusion of free will without he actual reality of free will.

I'll make a better choice next time. :)" I guess it keeps me aware that I always have the power to chose... maybe a funny way to look at it, but hey, I have the power the chose the thoughts that work best for me... :) many worlds just takes the pressure off while still holding me accountable for my actions and empowering me to do good and grow as a being. :) it's cool.

That seems highly likely, since almost everything in biology has gradients. There are things that are on the border of being alive (viruses), so there are probably beings that are semi-conscious. Even people are not always conscious and are semi-conscious frequently (e.g. falling asleep and waking up).

Set up a skype with someone who is at a significantly different longitude coordinate, and watch the sunset(s) together :) If the Earth was flat, the Sun would set at the same time at both places, because the tangent planes would be parallel at every point of the flat Earth's surface, so the Sun would cross them at the same time. However, the Sun will set at different times, so the tangent planes are not parallel, therefore the Earth is not flat by definition.

  • @borzumehrtoloui2059

    @borzumehrtoloui2059

    7 жыл бұрын

    From the MWI standpoint, the pilot wave is just the cumulative effect of all the other versions of particle interacting with it. The problem with the Pilot Wave view is that it singles out one of those versions as the only real one and demotes all the others to be constituents of the background pilot wave. In this, it is somewhat reminiscent to me of the Tyco Brahe's hybrid model of the solar system where all planets, except Earth, revolved around the sun while the Earth was somehow singled out and the sun and its orbiting planets revolving around it. Such hybrids are generally bad explanations their special singling out is ultimately a form of bias. This bias creates defects in their explanatory power. In the case of the pilot wave, it confines it to working on a specific basis all the time, has trouble incorporating spin, and is forced to accommodate for non-local effects. Even worse, the way the 'wave' interacts is very specific. It always interacts "as if" it was made by other versions of that particle subject to its particular setup. For example, if you put a barrier on one of the paths in the interference experiment, it effects the outcome only if the barrier is opaque to the passage of the particle. If it is transparent, it doesn't effect it at all. A general non-local spread out wave piloting shouldn't be so specific and idiosyncratic in how it acts.This shows that the addition of "as if" in the sentence above is superfluous. Doesn't add anything to the actual explanation. If you get rid of it, you get MWI back again with all its explanatory power. Anyways, that's my two cents.

    True, but that is only a problem if you had assume before hand what regular must mean. In the MWI, a cat that is alive in one universe and dead in the other is as regular as any other cat. The particles constituting that cat, by themselves, can be in a superposition of two or more states. Why not the cat that is made out of them? Oh, and you are very welcome. (BTW, that individual particle can be in multiple states at once is really is really the only reasonable way to comprehend how quantum computing works, for example. In the pilot wave model, it's pretty much like magic. In intermediary phase between preparation and measurement cannot really be considered as a sequence of well defined computational steps.).

    No. It's the only one that truly explains it all. What happens is that the calculation is done in all the branches in parallel and then at the end, you make the branches with the 'wrong' answer cancel each other out through destructive interference and the ones with the answer you want to compute to constructively interfere. Then you measure, which means you entangle yourself with them, and depending on how well that scheme of constructive/destructive interference went, these versions of you that see the right answer end up in the branch with the large enough measure or 'thickness' within all the branches. That's what under certain circumstances is interpreted operationally as the probability of getting a successful run of the computation.

    7:45 In the Copenhagen interpretation, the Schrodinger equation is not considered to be ontological outside of measurement (unlike in Many Worlds). For all the Copenhagen interpretation knows, the Schrodinger equation corresponds to the probabilities of outcomes upon measurement. Describing it as "alternate realities which merge into a single timeline with its wavefunction collapse" is misleading as it seems to imply ontology outside of measurement.

    There are two problems here which I would reeeeeally like to hear you answers: 1) uncountable infinities: There's always the talk about "a large number" of worlds that emerge from each quantum action in the whole universe. But for the double slit experiment, it is not only in which stripe the particle lands but also the exact coordinates on the screen so that large numder is not even infinity but an uncountable infinity. Correct? The "number"-thing wouldn't make sense anymore. And, if so, does the many-worlds-interpretation really still make sense? 2) Increasing mass: In the many-worlds-interpretation, where does the mass and energy come from, to copy the whole universe once for each possible outcome of what an electron does? Additionally: Am I the only one who sees the parallel between the many-worlds-interpretation and the infinite improbability drive in "Hitchhiker's Guide to the Galaxy"?

    At the double slit experiment it is more likely, that the photon will land in the middle, not at for example the side. It could have landed on any other spot, just with a smaller propability. If there are universes, in which every single event occurs, doesn't that make the propability of each event happening equally propable?

    But think about this: At every change, whether experiential, circumstantial, or genetic, "you" change. You're not fully "you"- at least not the you that you experience and identify with. But even a different you is still mostly you. I like to think of this the same way that we think of the observable universe. We each have our own distinct observable universe, because we each occupy slightly different positions in space time. Every time we move, or even by remaining stationary, the borders of our observable universe shift and change. So an alternative "you" is just as real, but they are their own being, with their own possibility horizon that is slightly different than your own. Your probability horizon extends out until so much has changed that their are no identifiable qualities of "you" left. That creates an outline of a complex, multidimensional shapes; perhaps the most comprehensive and accurate image of "you" that can exist in reality. Also reality isn't necessarily splitting at every juncture. More reasonably, all states in space/time/possibility simply exist, and have always existed, simultaneously in the grander universe. :)

    As as our knowledge of physics grows, testing hypothesis becomes more and more difficult. What if quantum mechanics is bound to hit an insuperable roadblock? Because maybe we won't be able to test everything we need in the future because we are just made of matter, and although we have found clever ways to make matter do what we want like forcing the Higgs field to produce a particle, it may not always be the case. Maybe we would need a deity-like perspective to test something like the many worlds interpretation, or questions about the Universe we haven't even began to question. I'll stop now before I have an existential crisis again.

    I just had a thought that would explain the particle wave experiment and why a particle is observed in a wave pattern. Conceivably when the particle passes thru the slit, it experiences a slight gravitational attraction with the barrier itself and depending on how close it is to the edge of the barrier the more strongly it's trajectory is pulled into phased trajectory. If all matter is a vibrating then there is a harmonic resonance between the particle and the barrier. This accounts for the stripes and the more or less empty spaces between the stripes. So it remains a particle but it's trajectory is altered by the harmonic resonance in gravity with the barrier. Are you with me? So we see it's disbursement pattern as a wave when in fact it's just the collective average of the particles predictable trajectory divergences. I think this explanation satisfies both conditions of particles and waves.

    Can I propose an experiment that could test the quantum multiverse theory for a person. (I'll be the person in this example so that people are not offended) If I replace the Schrodinger's cat with myself in the box and set the odds of killing to be extremely high I should still survive no matter what if the multiverse theory is correct. I mean after the experiment is over I'll be dead in most of those universes (and maybe even with a Darwin Award), but I'll be also alive in a few. So for me nothing happens in the box because thinking me always ends up in the universe where I survive. Not that I can share this result with anybody outside the box considering the statistics behind it. It just seems like you can't die if the multiverse theory is correct. Well, at least if you have some chance to survive. That's pretty neat :-D

    Spacetime please please answer this... So I was thinking about how we perceive black holes, and it seems that they are thought of as 3 dimensional spheres, but wouldn't they be a 4 dimensional hypersphere?? Hear me out, so every point in 3 dimensional space at the event horizon of a black hole would pull toward the singularity at the center, meaning that if you took point A then traveled 180 degrees around to the point exactly opposite point of Point A (call it point B) then you would have 2 infinite singularities that would connect at... well infinity (the 'center'). But my point is not the infinite curvature of the singularity itself, it's the equal yet opposite hypersphere that would be created in the negative space of the singularity. Let me put it this way, if space is stretched and constantly expanding toward infinity, like our own universe, and inside a black hole time no longer exists, it means that everything that has happened, or will happen, has already happened inside, like that of a 4 dimensional object.... .... For the love of science I hope this makes sense because I just read it again and it's not looking good... lmao

This can be applied to the entire universe we are living in now - our world line could just a projection of an event horizon of some larger black hole that we are contained within.
