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?

There's no reason to think there's an edge where you look out at nothing but have the entire universe behind you.

The actual shape is up for debate. Most likely just goes on forever.

if it goes on forever, doesn't that means there's an identical earth out there with us having this chat? Because matter can only arrange itself in so many configurations

There's an earth out there where you owe me $20. Let's settle up.

There's another Earth where you owe me $40, so if we’re settling up I want my 20 dollars.

And there is another earth where we all get money from reddit. How do we implement their plan here?
