On: Cosmological time dilation in the early Universe

[MrGLaDOS]

In the case of a universe of finite size, this analogy explains how there can be such a thing as a finite space without there being boundaries provided the space is (slightly) curved.

So this has less to do with an infinitely sized universe and more with the question of “What exists beyond the edge of the universe if it would be finite in size?”

Our universe is probably a black hole in another, larger universe we cannot reach. And then turtles all the way down.
