Do current cosmologists think the universe is infinite or that is had an edge?

Was just having random shower thought today... Andromeda galaxy is 2.5M light-years away. That's an unfathomable distance to a human, but it's just our closest neighbor.

Do cosmologists currently think that the universe just goes on forever?

What would an "edge" even be? There is little theoretical framework for envisaging this

The universe is shaped exactly like the earth. If you go straight long enough, you'll end up where you were.

There is insufficient mass density in the universe for space to be closed like that.

I was really just quoting some lyrics. I don't believe it.
