Actually, mathematics calculated that the Universe is finite but obviously something must exists outside of the border of the know Universe.
Quote from OPTIONAL777:
Is the universe physical?
Yes.
Is there a limit to the universe?
Has an end of the universe been found?
No.
Therefore the universe is a physical infinity.
Of course you can't see it because you are within it, just as a tree can't actually see the forest...
p.s. It is impossible to see a physical infinity in mathematics. Can't really believe you are that dense...unless you are counting the mind's eye as seeing, but you don't seem much like the insight type.
