Well that kind of makes me think, as we are looking up at the sky we are technically looking at infinite space. We can't see it but there is still no end.

Or the other main idea also means it has no end but is finite, basically the 3 dimensions of space could curve around, like Pac Man running off the right side of the screen and appearing in the left. Only the curvature is so slight that from our scale we cannot detect it, the cosmic horizon being such an insignificant fraction of the whole we cannot picture the universe being round!
