Question about the "edge of the universe" Okay, the farthter away you look, the farther back in time you are seeing, right? When you talk about seeing some object 11 billion light years away, you are seeing something as it existed a long time ago. So, since the universe is expanding, that means that 11 billion years ago, it was considerably smaller, right? Which means everything was closer together, right? So, now I'm tyring to understand this in terms of looking in two opposite directions and seeing two different objects 11 billion light years away in each direction. From my current perspective they seem to be 22 billion light years apart, but from the time/age issue they should be really really close to each other, right? Can someone straighten this out for me? And this just made me think of a related question. Can we see the same object by looking in two opposite directions (and without it meaning the universe is closed)? I was just thinking if we could see an object in one direction that was so old that it was from when the universe was really tiny, then anything equally far away in the opposite direction we see would have to overlap with that object if the universe was small enough back then. Which of course, make me want to ask, why can't we see the big bang itself at the edge of visible universe in all directions? Is this a limit on the power of our telescopes? Or is it because of the accelerating expansion of the universe so that those photons are just never going to reach us? Or is it from something else entirely? Thanks in advance for any help.
