My observable universe
I've been stretching the ol' grey matter recently tackling- how the universe is expanding in all directions, that wherever you are in the universe it will appear to be expanding in all directions etc etc
I understand that in whichever direction we look the universe appears to be homogeneous, and that my perceivable universe is limited by the amount of it that I can actually observe - that the further I look the longer I look back in time and the farthest viewable points away are those whose light has only just reached me here on Earth.
Does that mean then that if I were somehow able to look beyond the furthest images I can see that I would see a black sky where lights would blink on over time as the light from those objects reached me?
Also, if the universe if expanding faster than the speed of light, meaning I will never see the farthest objects as they are travelling away from me quicker than the light can make it back to me to observe, will I eventually reach a point where I can see so far that I can see no more? Are there any guess-timates to this threshold (if indeed it exists)?
