I have heard recently that it is possible using advanced telescopes to see the universe as it was not long after the big bang. Can anyone explain to me how this is possible? It doesn't seem to make sense to me.
If nothing can travel faster than light, then how can there be matter here for the light, or whatever it is we are detecting, to travel to. Did the universe and all the matter in it originally expand faster than the speed of light? Is the light from the big bang only now catching up? Or have I misunderstood something?
