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

So what parts are *not* expanding? If everything were expanding at the same rate, we wouldn’t notice, right? So the radius of the earth is not expanding… the radius of the solar system is not, galaxy is not? Where is that line/gradient, or how does that work?
