So it's possible the universe could in fact be infinite and expanding? A singularity has an finite volume but infinite density, correct? Then isn't it possible for an infinite expanding universe to have an end? I recall reading the(adsbygoogle = window.adsbygoogle || []).push({}); Theory of Everythingby Hawking where he talked about how if you were able to travel at the speed of light and make it to the end of the universe you'd end up on the opposite side. Would this also work for an infinite expanding universe? Also, is it possible for there to be more than one singularity?
