Because math is a descriptive language of the Universe. It's output. And that is why it is possible to "reverse engineer" the Universe by physicists, using math. But I also think that there is a prescriptive language of the Universe and for a few years I have been trying to find people / scientists seeking it... and quite frankly, I haven't found anything much yet.

@sandeepkumardas732 4 года назад

Hii.. I'm from... Bhubaneswar, Odisha, India... 🥰🥰🥰🥰

@Merione 4 года назад

Because we built it to be that way. Math is based on a finite set of assumptions that are taken straight out of reality and everything else logically and consistently follows from that. That means that math itself is deeply rooted in reality, and thus it's able to describe it so beautifully. Or at least that's how I've always thought of it.

The only problem with the version of you from another universe is that you are both the same person, you, apprehended through the senses of different observers in the same universe. That's all the many universes in one multiverse is. A copy of the universe in each observer's construct as their unique referent. Every observer has an internalised perception of the universe that is unique to them, relative to all other observers, including those who can see them in their own copy of the universe.

I'm still struggling with level 1. My problem? 1. The speed of light is constant 2. Time is not constant 3. Speed of an object as observed from different frames of reference is not necessarily the same 4. No object can travel at or beyond the speed of light, as observed from any other frame of reference (eg two objects travelling away from each other). As far as I am aware, the explosion of the big bang is no exception to number 4. 4 sounds intuitively incorrect, if you consider two objects travelling in opposite directions from an observer (say, from the core of the big bang). And this seemed to be the explanation for level 1, as given in the video. However, 4 is explained by 2. This is dealt with mathematically by the Lorentz transformations, and is verified by our real world observations. Whilst this video mentions that the speed of light is constant, it never mentions that time isn't. And that's where level 1 fails.

@Lucky10279 4 года назад

For number three, look up special relativity and the speed of light. You're right that speed is not necessarily the same between reference frames, however the way the difference is computed changes when we get close to lightspeed. I don't know the details off the top of my head, but there are a lot of videos that explain it well.

To me, the only way to bridge General Relativity with Quantum Physics, is that our reality exists in a multi-dimensional space (beyond our familiar 3D + Time), which is postulated by String Theory. Unlike Brian Greene and others, I do not think these extra dimensions are "curled up". Just like a "Flatlander" is trapped in its 2D space, we are likewise trapped in our 3D space. However, because of extra dimensions, there is plenty of room for multiple universes. The only reason I think this way, is that it resolves the Schrodinger's Cat Paradox, and removes the randomnistic nature of Quantum Physics. To me, the only reason for Quantum Physics' randomnistic nature is because we are trapped in our 4D spacetime. I probably described your Level 4 Mathematical Multiverse, but just in a different way?

@johnmckown1267 2 года назад

There are a lot of old sci-fi stories about level 1 multiverses. But they called them alternate time lines. The argument sounds similar to the wave collapse splitting the universe. The main difference is that in the stories, it was possible to travel between them. If FTL were possible & so going back in time also, then if a person did it and changed something, that simply split the universe into 2 time lines. The "old" and the new. But it would still break causality, so FTL remains unlikely (but I can hope).

I have never been good at math. I have a 5th grade math level. But I have never liked the multiple versions of you scenario. Though I view the universe/multiverse as infinite, and err on the side of the big bang being wrong. I am 37. When I was 25 I had an experience that has stayed with me. We experience life in a temporal way. Like a man walking across a tight rope. We think linearly. I was able to experienc in some degree reality at a higher dimension. It was a deeply spiritual experience in which past, present and future seemed before me. I look at this as God allowing me to experience a higher dimension of reality than my day to day life. It felt like leaving my 3 dimensional way of processing and thinking. I am sure it all sounds very strange. I also have no mental illness and no i wasn't on drugs! lol. But I experienced reality as pure infinity. No beginning or end. Since having this experience plus what I have read from scientists I believe the universe/multiverse is infinite with no beginning. Saying this was mind blowing would be an understatement.

There's actually another, even more mind-breaking thing you can do with multiverses. Just like there are multiple possible futures, there are multiple possible pasts. You might remember the past, but you don't remember *everything* about the past. When unknowns become unknowable - that is, Information loss - timelines can "merge". This can fit quite nicely with lvl 3 & 4 multiverses. It's also plausible to make this even more whacky. If merging timelines is more aggressive than "only when identical", then alternative timelines can have minor influence, and that thing you remember differently might actually have been different but only in some of the past. This kind of pattern is also inevitable if you try to model multiple continuous time dimensions.

@yeoman588 4 года назад

I would think that a Particle Horizon is not a bubble disconnected from all others. An observer at the edge of Earth's particle horizon would see Earth as being on the border of _their_ particle horizon, with a decent chunk of their observable universe also being part of _Earth's_ observable universe. A second observer located halfway between Earth and the first observer would have an observable universe that includes large portions of our respective universes. In essence, every point in space would be at the center of its own unique particle horizon. Does that fit within this theory?

@jonathanlevy9635 4 года назад

I think math is no more than a tool to describe what exists and even what does not exist. as a part of that, the universe itself cannot be a "mathematical structure" as you describe it because it is defined in a very limited way. eventually, there is a very clear line crossed between the universe and the tools to define it.

What I find the most controversial is that (UK) GCSE physics is taught vastly different to A-Level (which is basically pre university/college to the rest of the world). I was in the top set for physics, but decided to focus on English and the arts instead. But there are so many concepts the physics teacher declined to go into too much detail so as "not to confuse us"... With the first thing physics students at A-Level being taught was, basically, everything we were taught about the universe up to that point wasn't entirely true. This infuriates me, as if I was given even a taste of this I may well have continued with physics. The subject almost borders on philosophy, but with a scientific grounding, which is the stuff I'm most interested in. I get not wanting to overload my teenage brain, and honestly he was one of my best teachers who encouraged critical thinking of pupils own ideas. In this case though, I just wish he deviated from the curriculum a little to spark that interest in me.

In theory any set of information could be interpreted in a different way which is equal valid description. There needs to be a interpreter for the math to even have meaning. Of course taking a JPEG file and interpreting as a text document wont really mean anything to most. But you can not discount that to some interpreter that JPEG-text file may be a beautiful poem.

So in the first level there is suppose to be a particle event horizon... where we cannot effect the outside boundaries. But how is that possible? Because aren’t the boundaries effected by the system and then those particles would breach and effect the outskirt portion universe, kind of like a butterfly effect. I guess I would have to ask what would constitute that boundary, and how is that boundary defined...

@deandeann1541 4 года назад

The boundary is defined by the maximum speed that information propagates in a vacuum, which is the speed of light in a vacuum (300,000 km/second). The speed of light in a vacuum is determined by a fundamental number called the permeability of the vacuum. The reason this number is what it is is not known, but it is measured with great precision Also, and this is the part that should help you some, is that the boundary is expanding at the speed of light, so something outside of the boundary can't be affected by the boundary in any way until the boundary actually reaches it (no radiation from the boundary can expand faster than the boundary itself).

Just because someone has a high likelihood of happening doesn't mean it's a certain. Only a likelihood and this is where ideas breakdown but no one wants to recognize it.

Numbers can represent anything . Be it a small number or a very big number, or -ve values or fractions or even imaginary values! . Everything in the universe can be understood by numbers. Numbers can represent both energy and matter, the basic components of our universe . Math is a tool , which uses these numbers to give a logical explanation of how things work/behave . This is my understanding.

So, when something expands rapidly, it causes rapid cooling. If the universe actually expanded at the rate in which it is stated. It would have frozen solid the very foundation of everything, if there was nothing prior to the "big bang" then what would have caused the thawing of the universe?

@kydon1236 3 года назад

Also if there was rapid cooling, and it did cause the universe to freeze, how there did the stars and planets have molten centers, or heated objects.

If you think about the universe as an equation, you can always add and subtract at somepoint (given infinite time), meaning you can always expand the equation, and it will still eqaul the same. In math it's assumed that any of these variable eqautions are the same, just differently written; we'll describe it as u for universe. That would make both anything possible and inevitable. Math is are most fundamental language for value; which is all the universe really looks like to us on this sliding scale.

@jeremiahpratt2492 4 года назад

Could it then be said that looking at the universe as a whole is to lose all value; ergo the universe eqauls 0? Then the reason we exist is because given this imaginary time, it is possible to be written and unwritten.

I think the problem with multiverses is that media loves them too much. Level 1 is probably true, although we don't know if our universe is infinite or just much much bigger than the part we can see. But the others are merely thoughts that we can neither prove or disprove now, maybe ever. They are not solid physical theories. Level 2 multiverse is not an explanation for why laws of nature are as they are, it is just the thought that maybe they could be anything and we can only exist here. As an explanation that's almost as bad as god. Level 3 is perhaps best described as quantum philosophy. Level 4, well, we could even be a simulation, we couldn't know that. This is all fine, it's good to kick the limits of our thinking. But when media talks about these, it's always "Now scientists think this is the truth".

I loved this video. It raises some interesting questions. I think the Level 4 multiverse is there to deal with the fact many of the axioms from Zermelo-Fraenkel set theory are broken by levels 2 and 3 primarily. It seems to only play nice with axiom 1 (extensionality). I’m no mathematician or physicist in any real sense. Philosophy and art are my bag. I may be wrong here but the theories are fun regardless.

@omega82718 4 года назад

Set theory is not the only theory, furthemore that's an incomplete theory. The level 4 multiverse allow only Gödel-complete mathematical structures.

As a bored teenager I used to envision different shapes for the multiverse based on how I imagined they would interact with each other... Now I realise that I was imagining something between a level 1 and level 3 multiverse. I was mostly trying to fix plot holes in my favourite science fiction, but this is quite enlightening all the same.

@xmlthegreat 4 года назад

@@erik-ic3tp oh no, not my own XD. It was more of an effort to solve paradoxes in stuff like Back to the Future, or for example the time turner in Harry Potter and the Prisoner of Azkaban... It disturbed me that there was no logical way the chain of events could have started in the first place in order to continue to happen one after the other in the latter case for example... Since the universe would have to exist perpetually without a beginning, unlike what we believe is reality where the universe started from a state of unbeing that coalesced into being... But there's a lot more going on wrong with that as well, so yeah. To solve it I thought the universe was a set of infinite discrete states that stored all possible information, then transferred then between frames, and eventually the universe looped back on itself as the stack of adjacent state-storages bent a little each time until the final and initial states became adjacent. This was before I learnt that the universe was still expanding after the big bang, and at an accelerated rate. Sorry for the text wall...😅
