What is existence?

... that's not how math works.

 

2 things:

 

- There are, in fact, different , much bigger infinites (this is irrelevant in this case, though)

- "expansion" simply means that any 2 elements have, at limit, a greater distance between each other. This is fully possible, while staying within the same infinite subset of any metric.

Also, an infinite number of possibilities does not mean every single possibility, since if it's infinite there obviously can't ever be everything. But as for the universe being infinite, is there undeniable proof that it is?

No, we officially have no clue what is beyond the observable universe, because, well... It's not observable (as the edge" of the observable universe is parting at speed of light) For all intents and purpose, it does *not* exist, from our perspective, as there is no way to interact with anything outside of the observable universe (because, again, it's expanding at speed of light.)

 

I mean, what would the "nonexistence of the universe beyond ..." even be defined as? Mathematically, you can feel free to define your space however you like. Physically, again... no interaction. Your choice to say if any supposed entity with no interaction whatsoever with our point element "exists" or not.
