As as I know, we don’t know. As I understand it we can see ~13.9 billion light years away but not further, and so we don’t know what’s past it.
I’d love if an expert chimed in.
- findalex 4y agoI have recently wondered about this. When we talk about the big bang, the mostly-uniform CMB, accelerated expansion, etc. aren't we always axiomatically presuming the correctness of the cosmological principle (which, in a hand-wavy way says the universe plays the same game everywhere). I would think all we can say confidently is that the principle is working out in our locale.
