If the universe is always expanding, that means that there are places that the universe hasn’t reached yet. What is there before the universe gets there.

Question

I just can’t fathom what’s on the other side of the universe, and would love if you guys could help!

Answer 1

There may be nothing beyond the edge of expanding spacetime.

What really might make you think is that the universe will likely expand until all time and motion stops. All heat ceases. And then… something very special may occur – a reversal of entropy only possible as the end state of the universe becomes mathematically equivalent to the beginning.
