We continue reaching further and further back in time by observing galaxies that were born during the early part of the universe's existence. Some of the furthest galaxies we can see are 10 billion light years away, that is, their light has taken that long to reach us. In light of the Big Bang, if these galaxies are at the edge of the visible universe wouldn't they all appear on the same side of the sky? That is, the light from galaxies of the same age on the "other" side of the universe has not reached us yet? Actually, wouldn't all the galaxies at the edge of the universe that we can see all be concentrated in one general area of the sky?
