do you believe the universe is infinite in size?Physical size? No. But from our human perspective, it might as well be. It’s like cleaning. As clean as you get something, there’s always a way to make it “a little cleaner”. Or when if one starts looking at flaws, there’s always another flaw that one didn’t spot before.
Knowing when to say “good enough” (like trying to calculate the last digit of Pi) and moving to the next Step in the process, is important.
That’s where Pragmatics matters. We may be investigating what seems infinite but turns out to be a fractal pattern, with no mathematical bottom and what appears to be infinite is but a fancy loop.
