I was thinking a bit about the farthest parts of the universe we can see and I came to a few interesting questions that are maybe obvious to more studied physicists but new to me. Is the ~14 billion light year distance we can see in all directions slowly expanding with time? In another billion years will we see 15 billion light years in every direction? If so, does that mean the surface of that observable sphere is always going to look like the very early universe, just after the big bang? That leads to my next thought, from our perspective is the Earth located at the "oldest" point in space we can see?
