About infinity and all possibilities of Multiverse/Omniverse

[Ug Nagdi]

TL;DR

About infinity and all possibilities of multiverse/omniverse...

If all possibilities happen somewhere, can there be a universe where there are more explanations and content (articles, blogs, videos etc.) in that universe explaining about the multiverse, omniverse, dimensions etc.? And speaking of multiverse, why there is not enough information about omniverse? Most internet search results are from fictional TV comics. Can there be a universe where there is a version of me who finds every different version of search results when exploring the internet, like another universe which copies of me find more or different search results about multiverse and/or omniverse contents, including infinitely different versions of the possible answers to this question? I hope my question is understandable. Thank you in advance!

That's because virtually everything you've ever heard about multiverses, omniverses, or any other 'verse' comes from fiction. Mainstream science has very, very little to say about it aside from a handful of speculative theories about them. Mainly, the many worlds interpretation from Quantum Physics (which is an interpretation of the math, not something supported with evidence) and a few theories from cosmology that also have no observational evidence.

The real science behind parallel universes, multiverses, and omniverses is far more boring and far less voluminous than the fiction about them I'm afraid.

Thank you for the comment. This is what I am trying to ask actually, considering all the possibilities that can happen in Tegmark's level 1 multiverse, can there be a universe where such 'verses' do not come from fiction and we have more knowledge on such theories? This touches upon the rest of my question above, any answer is much appreciated to that parts as well.

Just make up whatever scenario you like and unless it violates physical laws, then sure, it could probably happen in one of these mythical "other" places. As you can likely tell from my tone, I don't believe it for a minute, but that's opinion.

That depends entirely on which sorts of 'verses' are actually fiction vs non-fiction. Tegmark's level 1 multiverse, which is still just a single universe really, is about as 'factual' as you can get. Assume that the universe is VERY large, much larger than the observable universe, at least 10^30 meters across (roughly), and assume that the laws of physics are the same everywhere. Then due to pure chance there should be a copy or near-copy of our own galaxy somewhere out there in the 10^(large number) galaxies that should exist within a volume of this size.

Once you get beyond this type of 'multiverse', things rapidly become more and more speculative and less supported. Obviously any type of 'verse' that isn't a real, physical 'thing' cannot exist, and moving 10^28 meters in one direction doesn't change this.

Even if there were an infinity of universes: there is no guarantee that in one of them, you wrote the Magna Carta, ruled the world, or were a member of the Beatles [or fill in your own crazy scenario here]. It would still follow some set of physical rules, and there are plenty of outcomes that could never be expected to occur.

The reason sci fi references parallel/multi universes and the like: it makes for a simple premise for entertainment purposes. Also, how would people in other multiverses know more about this subject than @Drakkith and our other distinguished posters on PF? I definitely believe this is the best multiverse to be asking your questions...

Thank you all for the answers, I understand the overall answer would be a ‘yes’ to my question?

I don't know, as your question talks about things which are possibly not infinite:

"another universe which copies of me find more or different search results about multiverse and/or omniverse contents, including infinitely different versions of the possible answers to this question"

If we're all using the same physical laws, then I don't know if there would be infinitely many possible answers to the question.

As a matter of actual physics. your question is unanswerable. The physics answer is that in "multiverse" models, all possibilities are realized which are consistent with the physical state of the universe and the laws of physics. But we don't have exact knowledge of what that state is, so we have no way of saying, as a matter of physics, what possibilities are consistent with that state.

As a matter of vague, informal, hand-waving speculation, people usually assume that anything they can imagine is possible. That is basically what you are doing in your OP, and what even physicists who should know better do in pop science contexts where they don't have to actually back up their speculations with physics. But as a matter of physics, we have no idea which of the things we can imagine are actually possible, as in, consistent with the physical state of the universe and the laws of physics.

Since level 1 assumes different versions of the universe, then different versions of us could read and write different versions of everything we see on the internet. Thinking, believing and writing about anything does not violate the physical laws we have... This is what I meant

Sure, but as there already are many articles and theories about such content in this universe, then I think in level 1 multiverse there can be slightly or completely different versions of such writings, including different verisons of us reading or writing them...

Thanks for the comment. I only thought of a slightly different situation here- which sounds highly possible than the examples you display: that there could be another universe which copies of us find "more or different search results about multiverse and/or omniverse contents, including infinitely different versions of the possible answers to this question"

 

[PeroK]

... including different verisons of us ...

What defines a different version of you? As opposed to someone who looks like you?

 

[PeterDonis]

You can speculate all you want about such things, but unless you can give specific references, they're irrelevant for discussion here. We can't discuss the content of something you're imagining that might not even exist, and even if it did, none of us here can read it.

there could be another universe which copies of us find "more or different search results about multiverse and/or omniverse contents, including infinitely different versions of the possible answers to this question"

Even if there is, we can't perceive it, so there is no way for us to know anything about it.
