I'm aware that space/time is expanding and that the red shift that far off galaxies exhibit is due to the expansion of space/time shifting the wave length of light towards the red.
What puzzles me is that if space/time is expanding, would that not include the photon and its motion too?
Also, if the far off galaxies are moving away faster than the near ones, would not the photons and their motion 'shift back' as it approaches our telescopes?
If these are dumb questions with obvious (well, obviously not to me ) answers I appologise in advance; I normally hang out in the 'Is it Science' campus and cosmolgy is a bit of a new frontier for me.
Cosmolgy please.

Thanks for the 'point' nature of the photon mate.
I guess I meant: is far away space is receding quicker than near space? But I think its because of the 'amount' of intervening space that is expanding is huge.
I think I have answered my own question here, lol.
