    Code for solving the Schrödinger equation by Jonny Hyman available here: github.com/jonnyhyman/Quantum...
    I learned quantum mechanics the traditional 'Copenhagen Interpretation' way. We can use the Schrödinger equation to solve for and evolve wave functions. Then we invoke wave-particle duality, in essence things we detect as particles can behave as waves when they aren't interacting with anything. But when there is a measurement, the wave function collapses leaving us with a definite particle detection. If we repeat the experiment many times, we find the statistics of these results mirror the amplitude of the wave function squared. Hence the Born rule came into being, saying the wave function should be interpreted statistically, that our universe at the most fundamental scale is probabilistic rather than deterministic. This did not sit well with scientists like Einstein and Schrödinger who believed there must be more going on, perhaps 'hidden variables'.
    In the 1950's Hugh Everett proposed the Many Worlds interpretation of quantum mechanics. It is so logical in hindsight but with a bias towards the classical world, experiments and measurements to guide their thinking, it's understandable why the founders of quantum theory didn't come up with it. Rather than proposing different dynamics for measurement, Everett suggests that measurement is something that happens naturally in the course of quantum particles interacting with each other. The conclusion is inescapable. There is nothing special about measurement, it is just the observer becoming entangled with a wave function in a superposition. Since one observer can experience only their own branch, it appears as if the other possibilities have disappeared but in reality there is no reason why they could not still exist and just fail to interact with the other branches. This is caused by environmental decoherence.

Then there should be some people just living for a very long time in this universe, too. And with long I mean very long. (Maybe as old as we humans are) So i think this theorem has to be false!

    This video reminds me of how our social circles and interactions can shape our lives, much like quantum entanglement. Positive influences tend to lead to positive outcomes, while negative environments can result in negative outcomes. It's as if we're all part of the same waveform, influencing each other's destinies.
    This perspective can also shed light on sudden tragedies. Even individuals with promising futures can face unfortunate circumstances by being in the wrong place at the wrong time. It underscores how the entanglement of others can impact our lives, regardless of our positive influences.
    Moreover, the uncertainty principle in quantum physics extends to unexplained phenomena. Until we gather enough evidence to prove something, there's a probability that it's both true and false simultaneously. This emphasizes the mysterious aspects of our world that remain unexplained until we uncover more information.
    As for the speed limit of the universe, I can't help but wonder if it exists in a state of uncertainty. It could be the familiar 300,000 kilometers per second, or it might be part of an infinite range of possibilities. However, it's crucial to exclude possibilities we've already proven false, such as any speed limit lower than what we've observed. Just a thought.

    I've never entirely understood the theory under this, but I for a long time I have thought about it as: there is a universe/world/dimension for every possible position of every particle in the universe. That is not infinite, but it is extremely close to it. Of course the probability of some arrangements are higher than others, so there will be far more universes where e.g. a pile of sand remains a pile of sand compared, versus much fewer universes where a pile of sand spontaneously forms the alphabet, or becomes the Eiffel Tower.

    • @evanallen7896

      That is correct. The vast majority of worlds are completely normal. There is a similar lesson when learning about the second law of thermodynamics. It is technically possible for broken glass to unbreak, and it will definitely happen given enough time, but it is extraordinarily unlikely.

  • @tomwithuhn9472

    Your many worlds explanation is a lot more bananas than the crazy idea that there are different rules for observed or not. The different rules idea is a simpler Ockhams razor than universes splitting and energy interacting across worlds.
    You could also say the wave function super collapses the moment it interacts with anything.

    • @evanallen7896
      @evanallen7896 Před měsícem +1

      You couldn't be further from the truth. You are severely mistaken about Occam's razor. First off, the multiple different worlds in MW come as a conclusion, not an assumption. If something strange turns out to be a consequence of prior assumptions in a theory, then it doesn't make the theory any less likely. Occam's razor calls for fewer beginning assumptions. Whatever comes as a consequence doesn't affect Occam's razor since they aren't additional assumptions. Secondly, if you listen carefully to what Carroll is saying, you will notice he makes the point that there is only one single wave function. This seems to conflict with the idea that there are multiple universes. Carroll explained this by saying that any branching is a non-fundamental human description of what is happening, but really the different worlds are part of the same wave function, they just almost never interact. MW is just what you get when you assume that there is one wave function and it obeys the Schrodinger equation. That's it. Extremely simple. Moreover, other interpretations do in fact use the same assumptions as MW, but then they make completely unnecessary additional assumptions that are exceptions to the previous rules. It is completely unnecessary because MW is already as simple as you can get while still getting quantum mechanics. MW is just what you get when you take quantum mechanics seriously, it is even debatable that it is an interpretation at all. Adding on additional assumptions that don't follow the Schrodinger equation for no additional benefit, is extremely bad according to Occam's razor.

      " Jesus...I've seen this before!" Where I had seen it was during an LSD experience about 1967. The Amazing thing is, it wasn't until about 1972 while traversing Logan Airport a Hare Krishnna monk, saffron robes and all walked directly up to me and handed me a hardbound copy of the Bagavad Gita and simply said " this is for you"
      When I opened it up and the first thing I see Is the actual representation of Krishna and all of his MANY WORLDS self i just about had an LSD flash back.
      I have EXPERIANCED, WITNESSED the ever splitting reality of reality. I had seen Krishna 5 yrs before I had any inkling of Hinduism. Am I a Hindu now or ever? Fk no. I'm an idiot. Yea...I perused the Gita for decades. Kept it on my night stand. Kept it in the Vberth on my sailboat. Did I GET anything out of it? Na. I get more out of physics lectures on quantum mechanics.

      Cats have a high temperature and emit lots and lots of photons. If you want the cat to be in a superposition, you need to avoid getting entangled by the cat. If one of the photons from the cat interacts with you, now your wave functions cannot be described separately but instead as one wave function. So you yourself would get into a superposition. If that happens, one version of you would see cat alive and another would see cat dead. As for why the cat was already alive or dead before you open the box, it is because it is basically impossible to shield the cat from the outer environment. The box isn't good enough.

    your stuff just keeps improving.
    I'm not an academic, but:
    If we would be in a simulated reality,
    what would be the computational power of running such a reality?
    especially if you consider than the more we evolve the more we can observe... branching out the reality wave function even more.
    how can you say that what you observe or somebody else does, does not involve "Environmental decoherence"?!
    From observing far out the universe to sub atomic level the more we observe the more we get entangled. The more we discover and understand the more we get entangled. Is that the reason the universe is expanding and accelerating?
    This theory seems exacerbating an infinite possibilities of realities.
    How can something simulate that?
    Does This theory collide with a possible simulated reality??
    too many questions

    • @bschwand
      @bschwand Před 15 dny

      In a simulated reality (i.e. we live in a simulation) all this becomes much simpler (and consistent). Actually the more I learn quantum physics and the more I think we live in a simulation.
      In a simulation, multiple universes are not necessary. The reason there is a wave collapse is simply because that is the point where the simulation resolves its necessary state to be able to continue the simulation. Just like in a video game. Not all objects or elements are kept active and simulated, only those important (interacting) in the simulation. Any object only exist because it has been looked at or interacts with something else. That is consistent with the fact that conscience is a necessary component of reality (i.e. a conscious observer is required for reality to exist or form). Until then, everything is virtual, we know it's there or has potential but has no fixed characteristics, i.e. is a probability or wave function. When interacted with, it comes into being, thus the wave function collapses.
      Simulation theory also solves why everything is actually quantum (pixelated in space and time) and not continuous (because the simulation saves energy/memory by only representing and keeping tracks of that is interacting in the simulation). Time is not continuous as we know, in a simulation it's because there is a clock on which ticks the simulation advances.
      It also solves how things can be entangled (i.e. spooky action at a distance, at faster than light speed): the simulation runs and resolves everything on each clock tick, that can take however long outside the simulation but inside the simulation it appears instant since... we are frozen in-between clock ticks.
      To me the simulation theory seems much more plausible that the multiverse...
      And consistent with our own progress too. If we came this far in 50 years, computation and simulation-wise, imagine what a technological civilisation say 50000 years old could have already achieved. Seems very probably the capability to simulate an entire universe could have evolved. And if you take into account the size of the universe and time it has existed, the probability we are NOT in a simulation is close to zero.

      @69k_gold Před 3 lety +109

      Sean's description of parallel universes as air particles is accurate. You see, two air molecules never occur in the same position in space, in a similar way, it's impossible for us human beings or even any other particle made out of quantum particles in our universe to interact with the other versions of themselves cuz it'll break the reality. If we actually create a portal into a parallel world, it just shows that all the particles that are interacting in both versions exist in superposition while observing, which is not possible according to Schrodinger's equation.
      So yeah, it's unlikely that your lost socks or guitar picks went into a parallel universe.

    There is a very good video on this by Sabbine Hossendelder on CZcams that perfectly explains this topic. In her video she explains, "Imagine sending a postcard each to Bob and Alice. On Bob's postcard is written the number -1 and on Alice's postcard is written the number +1. From their perspective they do not know what number will be on their postcard so it could be either -1 or +1 although the result is already determined because we know which envelope was sent to each person. Alice happens to open her envelope some time before Bob opens his and she then knows that she has the +1 postcard which means Bob must have the -1 postcard.". And this is what a wave function collapse is. Before any measurements are taken we do not know what the outcome will be but as soon as we do make a measurement, or open our envelope, we know the outcome for both our particle and the one it is entangled with. There's no instant transfer of information, no spooky action at a distance. The outcome was already certain but because we lacked any data we could only describe it as a probability wave. As soon as we measure one particle though we know everything about it and also everything about its entangled partner. No magic, no parallel realities, no splitting in half. Just going from not knowing to knowing.

      The video is saying that anything that doesn't violate the laws of physics is possible. This isn't profound. You are also ignoring when he said something along the lines of "Yes it is technically true that there is a universe where I am the president, but it is extremely unlikely. When you say this to people, they ignore the fact that it is unlikely and say 'But there's a chance!'" In fact, most things are impossible. All phenomena obey the strict laws of physics, and they have no stringency. They are universal (haha).

      vsauce has video about physical laws and their role in universe as explanations. Michael tells the same - laws are not the reasons of events in universe. They are just assuming the relationship in-between. He tells about nail in the desk and the shadow from it. Length of the shadow is determined by physical laws and depends on height of the nail. You could even calculate the height of the nail by knowing length of the shadow and position of light. This is the law. BUT length of the shadow isn't a _reason_ for height of nail. Nail's height isn't caused by length of its shadow. These values are tangled but not in cause-effect way. It's just our way to describe relationship in-between. Absolutely real and existing relations but NOT the reasons of things. You're talking exactly about the same. Our math is the way to find out relations and consequences, not the way to discover the reasons. And our theories are always just a models. Robert Anton Wilson tells us not to mess territory and its map :) Laws of physics are our map of reality. It's not a good idea to mess it with reality itself :) Maps are useful are reflects real things but they are just a models.

With this view, each time you run the experiment you'll create 2 different "worlds" one which got A and the other got B, if you repeat the experiment a lot of times you'd expect to have about 90% As and 10% Bs, but creating new worlds will esentianly produce all the possible outcomes, how do the probability weights work here?

    Is it possible to add a function of entropy to the possibility function? If the entropy of a state much lower than the other one, the possibility dramatically would be decreased?

    Schrödinger would defo have thought the many worlds interpretation was more ridiculous than the cat

    One of the only media representations I've seen on this that seemed to understand that Schrodinger was NOT trying to prove the cat was both dead and alive, but rather trying to demonstrate a problem with quantum theory.

      Yes, it was designed to show how the laws of Quantum Mechanics don't mesh with the real world as the cat isn't dead or alive at the same time

      Right, he was trying to show how ridiculous that assumption was, despite the fact that the assumption had to be true for the double-slit experiment to work.

      yall ever just break the quantum theory by manipulating tickbase? I actually call double-slit - double tap, you just shift ticks or break sequence while doing swap and it breaks perception of time which causes whole issue with relativity and quantum physics

      I wouldn’t be surprised if someday we find out that the universe is infinitely big or ever expanding in all dimensions, not just in distance or time. Maybe all we are is some sort of energy that simply exists, and everything that happens(including its existence) can be described as entropy. That way it makes sense how the Big Bang happened without anything “prior”, since we all are just waves of energy and it simply transcends states infinitely. So maybe everything is infinite in infinite ways that it could be infinite(like the multiverse theory). Then perhaps physics could be treated as math

    There is also another version of professor Carroll in a parallel branch where he strongly disagrees with this theory and even wrote a book about the insanity of such a possibility

      Depends. It may not have any probability of happening. It's not every "imaginable" scenario, just a whole bunch of them.

      Danny West - Given the trillions (at the very least) of copies of himself that branch off every second, the range of possibilities-for everyone, not just Carrol-is extreme!
      If Many Worlds is true (and I don’t think it is), I’d say there’s a 99.99999999% chance that there’s a Sean Carrol who ate his own mother, live on national television, but only had to serve one week in prison. He then went on to cure cancer, build an interstellar spaceship in his backyard out of popsicle sticks and dog feces, then became President of the USA, before finally eating his father on national television and then giving himself a Presidential pardon.
      Also, this version of Sean has three eyes (all different colors), and hair growing out of his tongue.
      And their are literally trillions of similar Seans “out there”.
      The end.
      Oh, and he’s married to Michael Jackson, who’s still alive (and an admitted child molester) in this (series of) branch(es).
      The actual end.

      Toaster R - None of it violates the laws of physics, and I don’t see why any of it would be inconsistent with the starting conditions at the Big Bang along with quantum “randomness”.
      _EXTREMELY_ unlikely for any given branch, but not unlikely for 10^367 (or whatever) branches per second across the whole universe. It’s ultimately just every different arrangement of particles and atoms that is logically possible, doesn’t violate physics, and is consistent with the starting conditions.
      I suspect that Sean Carrol would have to admit that it’s likely a reality.
      (note: I’m not a physicist, and my understanding of QM is severely lacking.)

      Everything humans can imagine is much broader than anything that is possible.
      For example, fire was required to discover iron, it is IMPOSSIBLE to have a civilization in the Iron Age that hasn’t discovered fire.
      Likewise, Sean Carrol HAD to have been born in the 20th century, otherwise he wouldn’t have the same parents, wouldn’t look the same, wouldn’t have the same upbringing, etc, so you couldn’t call him Sean Carrol.
      Likewise, curing cancer may one day REQUIRE technologies that currently don’t exist, like iron absolutely needing fire. And because of this, it may be impossible for cancer to be fully cured before the 21st century unless a significant change in history occurred (one which would make the population of people very different).
      In this sense, it may be PHYSICALLY IMPOSSIBLE for Sean Carrol to have cured cancer in ANY timeline, and thus no Sean Carrol exists.
      Just because you can’t immediately think of how something violates physics, doesn’t mean it doesn’t. And the more complex the system, the more likely it is.

    Thanks for the video! Can you explain the falsifiability of the many worlds model? It’s feels like there is no way to actually conduct an experiment that would show the existence of different worlds because those worlds don’t interact.
    Another question - can the branched worlds arrive and merge to a same world ?

    • @vitulus_
      @vitulus_ Před 4 měsíci

      Many worlds model is falsifiable if a collapse is found. If there is no collapse and the universe does indeed follow Schrodinger's equation, many worlds is likely.
      Yes, branched worlds can _technically_ merge, since Everett's interpretation implies reversibility you can reverse all velocity, etc., and you will find that the worlds converge back again. The reason this doesn't happen forward in time is because of entropy. This is merely a statistical law, but it's not physically impossible (although is incomprehensibly unlikely to ever happen).
