I've read that astronomers have received a light (a photon) 13 billion years old. Here's my question:
If we start to turn the clock backwards all matter, energy, etc should start heading to the original "point" of the Big Bang. Then how come that the photon we have received and the stuff that makes planet Earth end up at the same location (the Big Bang), for the same amount of time (13 billion (+ a few millions but who cares)) by traveling with different speeds? (light travels with maximum speed, matter travels with less speed, etc)
EDIT: I know that the stuff that makes planet Earth was not even here, say 10 billion years ago: small particles form bigger ones, bigger ones gets shattered to smaller ones, etc. But imagine a hydrogen atom that some how managed to survive all the way up to here intact straight from the Big Bang (of a few million years after it). How come the atom gets here before the photon?
PAUSED: It looks like there are a lot of things I need to learn (or relearn) before asking the same question again.
