TopicThe Paradox of an Infinite Universe

This stuff's interesting to think about. If the universe is finite and there is an edge, intuitively it feels like there should be something on the other side of that edge. But if the universe is all of space and time and all the matter and energy in it then there can't be anything outside it, not even empty space. Just literal nothing. Because if there were something there then that something would be part of the universe.

But like the video gets into even if the universe is finite it's so huge that on human scales it might as well be infinite. Even just our own galaxy is almost unfathomably huge and it's estimated that there are several hundred billion galaxies in the observable universe.
