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!

Apparently, it’s not even known whether the entire universe (as opposed to just the observable universe) is finite or infinite ([Wikipedia](https://en.wikipedia.org/wiki/Universe#Size_and_regions)). This doesn’t directly affect your question, since either way the expansion is just things in the universe getting further apart, but it’s interesting to think that there might not even be “places the universe hasn’t reached” at all.
