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.

DTStar then they find out lol.
Precisely!
Ummmmm...that's a good one.
Now in this Universe I will tell you why it probably doesent exist: If this theorem is true every time when someone dies in a lonely room, theres another universe where this person will live longer, and another one where it lives longer,... . 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!

I have seen the multiverse.... I have witnessed the unfolding duality of the super position of reality. When I first saw the Jimi Hendrix album cover Axis and Jimi as the many incarnations of Krshna I said : " 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. BUT ! The parallel between them is UNDENIABLE. I have witnessed reality streaming right at and through me as 2 film strips and me frozen between them . I'm just looking for anyone with similar experience. Compare notes. Try to figure out how to move between the different realities....maybe..choose carefully !!! The rest of you can chalk me up as insane. Hare Krsna😅

Very good explanation. David Deutsch's the Fabric of Reality is another beautiful way to approach understanding quatam mechanics starting from a simple object like a torchlight
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.
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.

Great work. We need educators like you
this explanation of schrodingers cat is very different from most out there but makes way more sense. in all the other versions I have seen, the cat is in a superposition of alive and dead but that changes when you open the box and when you open the box it becomes one or the other.
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.

I am u from a parallel universe.
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.
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.

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 far, I am convinced with the many-worlds interpretation of quantum mechanics. My only concern is that the idea that every quantum measurement creates multiple parallel realities prompts questions about how energy fits in this framework. In classical mechanics, the conservation of energy states that the total energy in an isolated system remains constant over time, in that none is created or destroyed, only transformed and redistributed. If applied to the many-worlds interpretation, each multiversal branch, which is representative of a different outcome of a quantum measurement as a result of wave function collapse, would conserve energy within itself. In other words, the total energy across all branches remains constant. However, we have to take into account quantum fluctuations, where energy can briefly pop up in a tiny space due to Heisenberg's uncertainty principle. These fluctuations are inherent in the quantum nature of reality and can lead to temporary violations against energy conservation within certain constraints dictated by quantum mechanics. The way I see it, these temporary violations are observed only in one multiversal branch. With the realization of all possible outcomes of a quantum event into separate branches, each branch will have its own probability amplitude. From a statistical perspective, the overall energy distribution across the multiverse would follow probabilities dictated by quantum mechanics ensuring that while multiple scenarios are possible, they occur with appropriate probabilities that maintain energy balance overall, so the conservation principle is preserved. Nevertheless, we have to take into account decoherence, one that gravely affects the quantum system as factors like the observer, other particles, and radiation become entangled with it, leading to the apparent wavefunction collapse. Decoherence remains a significant challenge in quantum computing as it introduces errors and loss of quantum information after the collapse occurred. From a practical standpoint, the fundamental dilemma still remains: overall many-worlds-system complexity - the discussion of energy sufficiency in the many-worlds interpretation as understood within the framework of quantum reality is bound to intersect with broader debates about the nature of reality, the role of the observers, and the interpretation of quantum probabilities in various quantum interpretations. I guess, I'd have to study more of these in quantum field theory (QFT).
unless... there is an infinite number of worlds, that would mean that the law of energy conservation would not be broken. But it would also interfere the with the probability because it would mean that everything would be (1/infinite). But i find it easier to believe that parallel worlds dont exist and people came up with the idea when trying to understand probability. also im just a random guy knowing nothing so dont believe me if u dont wanna
“You have to remember that the whole idea of branching is just a human convenience” Glad he added this line in the end, this is exactly the point of all of it. The true laws of the universe are nowhere near the way we are describing it. It's just a matter of having a more fitting and more complete mathematical explanation of the bahaviour of the universe.
_"The true laws of the universe are nowhere near the way we are describing it."_ Or maybe they are, we have no way to know it. But fortunately it doesn't matter at all, as long as they work.
And woop-de-doo for that. I'm just going to stay in n the real world of having fun, loving our families, doing kind and generous things, and/or struggling for survival.
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.

Comment of the year hahahaha
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
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.
I noticed that you didn’t talk about Young’s experiment’s most important aspect that when you fire one electron at a time. There’s a wave pattern even then giving the idea that it’s a wave until it collapses on xray screen. Otherwise one can think the electrons might just be interacting with other electrons and creating the wave pattern.
A whole new meaning of “be the best version of yourself”.
i asked God about it, received an answer in a dream. There is not multiple worlds that exists, it is multiple POSSIBILITIES that exists. Once the timeline is changed, the old timeline no longer exists except as a known possibility. Strangely though, time is like a river and 'residues' from the old timeline can carry over to the new. Also prayers of the previous timelines still carries over to the new timeline even if that prayer no longer gets prayed. figure that

Do a behind the scenes vlog on how you make these animations in your videos.
“Me nodding my head up and down acting like I know what he’s talking about”
@Smoov Cat I have no idea what you're on about, but I totally agree
Every time there are options, every option or path is taken. Example: You are at a cross roads, you can walk 1 of 3 ways and in actual fact you will walk every way, but to do that 3 realities are made and they are made at the moment you take action.
😂😂😂. My neck is hurting also !
@Smoov Cat Consciousness is transcendnt and is fundamentally indescribable in chemical terms
Joe Walker Yeah but those options are also every single alternation/superposition that exists
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
I dont know why but this all just makes complete sense to mem i dont find hard to think or understand that the universe is the whole wave function and we arent spliting it, we are just experiencing a slice of it
When you pull in gacha games you can see the drop rates of different rarity characters/equipment but the drop you get is the one you experience, but from the probability list alone there are different branches in which your drop is/could've been different, for better or worse or maybe the same, but it's not in your lived perceived experience/observance, did I get it? It just makes sense. And then other random videos about alternate timelines/history just explore glimpses into the other branches unexperienced by the current "reality" that isn't this one...eh at least in (gacha) games you can go make alts/rerolls to experience the simulation of experiencing the other branches too.
Is there a part 1 to this? I feel like I just walked into class 30 mins late.

Try watching a simpler video about Quantum mechanics to get an idea about the basics then watch this video
same here, lol. The video wasn't too accessible is my critique.
Haha he is talking about more advanced quantum theory.
Me watching this instead of doing my HW* Me to my teacher- I did my HW but I did not do my HW, it is in superposition, don't check it, it would be wrong measurement
Great answer, you would definately make him/her day :D
As a high school physics teacher, this would make my day
Then I would answer that your score is now also entangled and you will measure it until the end of the semester. Now you'll have all the suspense a whole semester. You're welcome.
If the class you skipped your homework on is quantum theory, then you may just place out of the class for saying that!
You need more likes.
By that logic energy should decay in each copy of reality we are present in (as branching happens energy is split according to the square of probability) which yet again debunks this idea. Or perhaps this is the explanation for the expantion pf the universe. One could think of the expantion as a decay in energy. One could argue the expantion of the universe is just a dialation of energy density and after renormalization this is just energy decay. And as the universe expends energy decays and interaction rate changes and thus splitting rate changes changing the expantion rate - which explpains another weird phenoma. Have a good day yall!
14:00 If the number of splits is finite, then not everything is possible. Then only a select number of states is possible. Unless for every split, there's an infinite number of outcomes that occur from the Schrödinger equation.

Getting the momentum of one can give you the other since they have the same properties and hit each other at the same speed and I think you've seen two things do the same. Basically that.
@Aksi Dent I think the fact that the example is having two electrons collide is making people overanalyze it. The obvious part doesn't even need to be in quantum physics. It's like having 2 identical balls and have it hit one another with the same speed. You'll see that the momentum would be the opposite of each other.
Great video! I just wanted to say that if probability is equal to |amplitude|^2 then you’l have, at some points, an infinite number of nonzero probabilities adding up to infinity when they should add up to one. Probability density is equal to the |amplitude|^2, probability is found by integration.
You also need the postulate that the possibilities (mathematically, the eigenfunctions) squared (technically, the norm squared, or the eigenfunctions times their complex conjugates) add up to one. This is one of Bohr's postulates and solves the issue you've identified.
I think that your consciousness lives in the universe it believes is the most probable for you. This also explains how your beliefs and convictions can influence your future (= the path of your consciousness).

Hello there brother
Meanwhile in a parallel universe there's a comment that says there are parallel universes
I have nothing but respect for people that understand this stuff fully………. In this universe.
I think you cannot. There are questions where we can only make educated guesses with mathematical predictions. It helps to get a better understanding of what we precieve, but it doesn't prove anything. The prof there gets pretty far with rational logical thinking. But when it comes to quantum physics we meet the limits of our perception (even enhanced with sensitive tools). We don't even fully understand how our own brains processes this input. But still Props well deserved.
And, of course, there's still the bizarre phenomenon of "Dark-Respect", that strange riddle dealing with all the missing Courtesy & Politeness in the Universe...& don't even get me started on the conundrum of "Anti-respect"; for instance, did you know that when Respect & Anti-respect collide, what occurs is sweet F.A.?

in some parallel universe I understood this video and got sleep and didn't think about this tonight
Im understanding this as there are no choices in our universe. Everytime we make a decision or pick a fork in the road a new branch is created where someone takes the rest of the routes and thus there is never a singular choice made. There is no chance, in order for a choice to be right the universe needs to play out all possible choices to calculate the outcome.
