if the universe started as a point, i.e. everything was very close together in the early universe, then why do we believe that the further away an object appears the older it must be? surely, if everything was closer together at the beginning, and has been moving apart since, then the further back in time we look, the closer together things should appear. e.g. if the big bang happened 20 bn years ago, then a galaxy 20bn years old should appear to be on the doorstep, not at the other end of the universe. am i missing out on something? i have asked this question on several web sites and never received an answer.
