Comment on Multiverse

You’re getting into omniverse territory here, I think. But if accurate, then the dimensions without multiverses just lack the ability to perceive, observe, understand, measure, prove, or travel outside of their own universes. There’s a whole multiverse of such isolated bubbles that will “know” that there’s no multiverse, and we have a 50/50 chance of being in one.

That’s not how statistics works lol

If there are infinite universes, covering all permutations of all properties (i asume thats what they mean by omniverse), then there will be exactly as many universes with a certain property then there are without it. So it is actually 50/50.
In the “multiverse of all possibilities” there will be 50% without a multiverse

We’re getting into hierarchies of infinities here, look up cardinality. You can have infinities that can’t map to every possibility of a higher infinity

I know. But I case of the multiverse that many people think about, the one where there is a universe for EVERYTHING, there will be exactly as many universes where triangles exist as there are universes where triangles dont exist. And the same is true for everything else.
And it is exactly the same number, not just the same type of infinity. Because for every universe with triangles there must also exist the exact same universe without triangles (and vice versa), otherwise the multiverse wouldn’t contain all possible universes.

Omniverse is what you get when you sort multiple multiverses, that’s all. It’s a way of categorizing multiverses sharing some common element. Because infinity is so vast that it’s basically meaningless to us humans, so organizing it at least makes it vaguely easier to understand.
The dumbest and easiest way to understand it is with media franchises as an and analogy. All of Marvel is one multiverse, all of DC is one multiverse, all of Terminator are another, all of Star Trek another, etc. it’s sloppy but here’s my point across.
In reality it’s more like; this multiverse has universes with identical physical parameters, that multiverse has a slightly higher amount of gravity, that multiverse has a slightly different amount of weak magnetic force, that multiverse has a different speed of light, etc.
