>Let me offer a better question: is the universe finite or infinite?

What is the concept of infinity but the outer limit of our mind's ability to conceptualize?

[drdeca]

"Infinite" can be understood as "not finite" or "without limit", or "equinumerous with a strict subset of itself".

(I don't know why you switched from "infinite" to "infinity". I am opting to answer for the word "infinite".)
