Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
That’s what I believe as well. AFAIK from what we know the universe could be infinite or simply bigger than the observable part. But I think the only reason people default to assuming that it’s finite is that infinity is hard to grasp and that illustrations of the big bang show a point and then disks of expanding size. People assume that means the universe is a sphere but nothing contradicts what you say so there’s no reason not to believe that it’s infinite.
It’s fun to think it might just start going backwards or something because we have literally no idea what is actually happening, like it’s very possible we’ll never actually be able to see or measure anything outside the universe but there could be all sorts of things going on.
There is no center of the universe fwiw, there is no middle everything is expanding out from. Just a substrate that exists everywhere that inflates
