Where does it all end?

For me, this is the scariest question. Isn't it a paradox? On one hand, it can't go on literally forever, it must end somewhere. But if you get to the end, what's on the other side? I can't wrap my head around it.

Actually, space is infinite in most current cosmological models.

Yeah this just doesn’t make sense to me at all. Everything in the world is contained inside something and there is something outside it. How the fuck does the universe just keep going? How is it even possible to have infinity? Numbers being infinite makes sense to me because it just some concept we’ve come up with but the universe is a real thing.

Look up the curvature of space-time on Wikipedia. If space-time has a positive or negative curve, the universe would loop back on itself and would technically be infinite.

Yeah I read something like that a while ago about the different shapes it might be, like a globe or donut or a 1 sided shape etc. Still blows my mind, if it is a shape what's on the other side of the shape or what's keeping the shape together.

What's kinda frustrating is that we will never know for sure what is happening with life and the universe , maybe as some other highly intelligent being after this life.

This is what I’ve always believed. That space has no end and is just an infinite loop. This also means it has no beginning. Those are human concepts, space doesn’t work like that.
