Speed of light, hubble?

I am a pain in the neck, I know. Mr Hubble proved that galaxies are moving away from each other, we know the speed of light,. Can science dudes draw a motion line of galaxies, trace them backwards and say "The big bang(or whatever) happened here"?

    Definitely a lot of conflicting theorys on this subject , I guess the biggest one is the age of the universe itself which, According to theory, Is 13.7 billion years, But this is only based on the red shift and from nasa's all sky picture and Hubble's deep space photos which are limited by the barrier of light speed. Most scientists will agree that there is no reason to believe that our cosmological horizon is the end of the universe, so why put an age on it? One theory states that space is expanding faster than the speed of light so anything outside our own light horizon we will never see because the space in between is expanding faster than the light can reach us, However, Another theory sais that an observer on the edge of our horizon would have a light horizon of there own which would span another 6 or 7 billion years past our horizon and that this process could go on infinitely. So trying to reverse enginer the universe is impossible because we dont have a layout of it yet.

    Nope.

    That is the really annoying thing with relativity, is that whatever is moving away from you in one direction can equally be something that is simply failing to catch up with you, i.e. we're the one moving away.

    The immediate consequence is that it is impossible to find a center, an original point.

    Nope. The galaxies (at least, the ones far away from us) seem to be going away from ... us. But they do it symmetrically -- they are also moving away from each other.

    Much like the dots on a balloon when you blow it up. All the dots move away from each other, there is no "center" that they are moving away from.

    No, because everything is moving in every direction. There has not been found a starting direction.
