The universe could be finite in extent, but just continue expanding for infinity. I can have another sheet of paper that's infinite and put them one centimeter apart from each other and they will never intersect. And so when you embed infinities in higher dimensions, you got no problems at all. So there's a lot of variations on this geometry that make for fascinating thought in all of it.
What is infinity? Neil deGrasse Tyson and comedian Negin Farsad explore whether we are in a finite universe, the issues with infinity, string theory, and more with theoretical physicist Stephon Alexander.
