Thread: Observing the big bang / Looking back in time problem

This question started to bother me while watching a documentary by BBC about the Cern undergroud sciencecomplex.
It's generally accepted that light travels at certain speed and so the light we observe is basically a reflection of the past.

Now here's the problem:
How is it possible for us to "see" the light emitted right after the big bang. Initially there was this very small and very dense object that contained everything in our current space. Now after the big bang space has been expanding for reasons jet unknown. So basically we have travelled to our current location from the place where the big bang occured. And so has had the light that we are observing as the light from the big bang (well practically right after the bang)
So how can it be that we are here before the light we observe?

Well the first thing you have to understand is that "dense hot object" at the beginning of the universe was not in a particular place surrounded by empty space, it was everywhere because space itself was no larger than this "dense hot object". After the big bang the light is traveling in all directions from all directions. This is one of the reasons why we know that the cosmic backround microwave radiation is from the big bang because it is coming to us from all directions equally.

Thanks. Got to hand it to you Very nice way of putting it.
