Someone on this forum once told me that if the universe doesn't have an "end", it is because it is like a sphere, endless, so you could, eventually, and I am not able to imagine this, go back to your starting point while keeping a straight line, much like you'd do going around the Earth and coming back to the place you started.
So it's kinda confusing, but I'm asking if we could see our own galaxy (in the past) if we had telescopes powerful enough to see "around the universe". I don't know if inflation plays some role in it, but since the farther we try to see, the more lightwaves are being "stretched", we may have to try and detect kilometer-long (or even worse!) frequencies, if the light has gone all the way through the universe.
I am aware that at this stage, light emitted from the Milky Way would not have had the time to reach this far, and surely never will since the universe is seemingly expanding, but it's just to try and understand a little bit better the concept of "endless universe", much like when people believed the Earth was flat, and weren't even able to imagine it being round...
So, if we say the universe isn't expanding, and we wait long enough, could we be able to detect the formation of the Milky Way, with any technology needed to detect such a would-be far-away event?
