hi, 1. radiation travels faster than matter. 2. our earth was formed much after the big bang. The big bang goes like this. At some point in time and in some point in space (witch we cannot determent so we just leave the location open and say it could have happened anywhere) all the matter in the universe that we see today or don't see :), has been in that single point and for no reason at that point in time it started to spread out very rapidly. any radiation that got emitted should determine the expansion rate of that bubble. radiation gets emitted outside of the current matter boundary of the bubble and the pressure expands any lumps of matter or atoms that might have been formed or that were there already. all that radiation would have surely went much faster when any matter expansion. so does it seem logical to you that we still can see an event that preceded our own existence by so much and that we can see it in any direction we look??
