      Noone knows but they do keep finding more and more of it. At some point we might have to develop different instruments to allow us to measure larger spaces.

      We simply don’t know, and we might never know. We could never say that we have reached the edge – how would you know that it is the edge?

      As a biologist, I have no idea.

      It’s something I try not to think too hard about 😂

    Mathematically? It is not infinite but the universe is far, far larger than anything we can imagine, so for all practical purposes, it might as well be! Infinity is quite weird. You can google ‘Hilbert’s hotel’ and see how weird it is. There are some good articles and youtube videos that use Hilbert’s hotel to explain infinity.
