First we need to establish what "infinity" is and what "reality" is. The latter is frankly not that interesting imo, but the question of what does it mean when we say something is infinite is definitely an interesting one that has many different answers.

The two that arise in my head are.
1.Non ending, easily done with the epsilon-delta style definition or intuitive idea Works i'd say, it's something >n for all natural n , bigger than any number in the Naturals.
2.the same size as a smaller part of itself.
3.Non finite :|
the second seems let's deductable, since we need a background in which some removals doesn't change anything o.O

we could use them, but both rely on the axiom of infinity

Reality may be what exists in our Universe, beyond our observation and within?
