What is existence?

Nothing can be infinite.

The reason is simple, say the universe (or anything for that matter) is infinite, but then it expands by whatever margin, then it would be suddenly bigger than infinite. So therefor all things are finite. It seems to us like it's infinite because it's to big for us to comprehend. Of course it can grow, which just means it's bigger than it was (obviously :)), but still it's finite.

... 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.

I was not talking about math. In math infinity is abstraction, it's a concept, it's not 'real' because it can never be obtained, otherwise it would not be infinite.
In terms of physics (applying to our reality) nothing can be infinite. It doesn't mean you can't use infinity in physics for calculations, but it's just used in case a theory is insufficient to give a proper solution to a problem.
