Sounds like you have some weird issues with Disney more than anything else. You know this concept was around before Marvel movies right? It’s been a scientific theory for over a century and a common plot device in books, movies, and comics for longer than you’ve been alive too. The fact that you think Disney is paying people off to support the theory of the multiverse in the scientific community to promote their movies is frankly completely unhinged.

I have read similar ideas and they are interesting ( if well above my brain grade) but I think I am right in saying that in quantum physics ‘observer’ is really a term for kinds of interaction , it doesn’t actual have to be a consciousness? There is a certain elegance to the idea that there is some kind of natural selection process for universes that means while there may be infinite potential ones only some can be real?

One thing that you might find interesting is the idea that our universe is actually one with zero total energy. I couldn’t comment on its validity but presumably it could apply to multiverses too?

https://en.wikipedia.org/wiki/Zero-energy_universe

I’m not sure there is actually much in the way of evidence for these rather definitive statements.

It isn’t expanding into anything, it is (at least in this context) everything. It’s not really the sort of concept our ‘ape’ brain intuitions cope with very well.

Yeah totally agree here. As for a storytelling device it’s a little bit like “it was all just a dream” in that it somewhat diminishes the stakes. It’s ok they are alive in another universe type of crappy method for unkilling a character

Just an expensive message in a bottle w/ lower odds of any recovery by anything plus a hint of posible danger.. why even do it?

That’s a different multiverse theory where different areas of a potentially infinite cosmos have different laws of physics. I believe the OP is referring to the Everettian multiverse where instead of the wave function collapsing the cosmos “branches” into multiple universe. In this model the laws of physics don’t change.

It rubs people the wrong way for various reasons, mostly because a huge number of universe seems unreasonable.

Math is obviously extremely useful, but just because a mathematical formula exists does not mean that there is an equivalent behavior in reality, particularly one that there is zero real-world evidence to support and is unproveable. Perhaps that will change in the future (though I'd argue it's safe to say it won't any time soon) but at this time it is absolutely ascientific.

Multiverses are ascientific. And they are getting excessive attention because it seems 'cool' and scientists are all too happy to romanticize it for the attention. But we need to stop pushing it so much. It is akin to a religious belief, which is fine if you want to hold that belief, but don't paint it as scientific or in line with our current understanding. It is an extreme application of math (quantum wave function) to reality without the ability to test and validate, and zero evidence for it within our current scientific understanding.

would you close the door?

of course it's logical - it's just a personal compartmentalization/language thing

I'd prefer Universe be the base layer that encompasses all. otherwise - what would we call that Space? ...nvm

Perhaps it's something like different rooms in the same house, different houses on the same street, different streets in the same city, different cities in the same country, different countries on the same planet, different planets in the same star system, different star systems in the same galaxy, different galaxies in the same universe, and different universes in the same room.

>It's not expected for us to recover these in the future, but they will provide good purposes for search for extraterrestrial artifacts (SETA) missions mounted by other civilizations far from us.

That may not be a good thing. While we only have Earth and humans as an example, when a more advanced civilization encounters a less advanced civilization, most of the time, it does not end well for the less advanced civilization.

i wouldn't say a vector of infinite length could be considered a loop just because the numbers used to measure it are made of a repeating loop

but

i'll reverse the 2 point deduction if you draw me a cool picture

It is a really good theory because we have no evidence to the contrary.

Also guess what. There are loads of physicists that write fiction. Infact... an INSANE amount.

Gregory Benford (born 1941) Gregory Benford (born 1941) ... Carl Sagan (1934 – 1996) Carl Sagan (1934 – 1996) ... Robert L. ... Poul Anderson (1926 – 2001) ... Sir Fred Hoyle (1915 – 2001) ... C.P. ... Vladimir Nabokov (1899 – 1977)

If thats what they are saying... your statement i responded to is wrong.

Which was why i said it

But to be clear. Evidence shows that if there was another universe it would have to follow our physics. Because there are no other instances of anything different.

What could be infinite that doesnt loop? Infinite space is infinite space.

Pi. Contains every number in every organization which also means it repeats

If it goes forever than it is a pattern. A pattern of never ending loops.

Any set in an infinite system repeats or loops

Just what is it that our universe is expanding into, anyway? Why is there extrema room fo it to expand into?🤯

That makes no sense at all.

Again entropy. Infinity time doesn't mean infinity mass or energy. Its far more likely it would just become susceptible to heay death like the rest.

Furthermore... if it was truely industructibe in a way that is impossible in nature, no outside sources would be able to influence it. No pressute change, no heat, no cold. It wouldnt get to become a super fluid. It wouldnt subliminate.

That’s what they’re saying though. Laws that govern nature is measured in THIS universe. We don’t know if the laws works differently in another.

Thes laws of nature doesn’t fluctuate in THIS universe

>If infinity exists literally anything is possible and if it doesn’t that is a different story.

Divide one by three. You'll get endless threes without ever finding any other digits.

Divide one by seven. You'll get six repeating digits without ever finding any of the others.

Infinity doesn't mean everything has to happen. It only means there is no end to whatever happens.

> if true then some of them must be able to contact others

Nope. It may be an impossible outcome.
