Does "infinity" even exist in "reality"? It is after all a human way of conceptualizing an idea, one which can be applied to space or sets or other hypothetical constructs.

In a certain sense, yes. There's no "end" to space but you can never get to infinite, because that would be the end. As a number it doesn't exist because you can't reach it. but as a concept it exists because there can't be an end to space.

Are you saying that the universe is infinite? Because that's not really a commonly accepted idea among cosmologists.

No, but space itself is.

What is space? What do you mean?

Basically I mean everything.

space is actually a lack of something really

Space is Dark Matter and Dark Energy.

I think "space" is just a manner of conceptualizing the information our senses give us, so to apply other abstractions like "infinity" to it doesn't necessarily imply that it has some sort of external "reality" from human experience.
