Is it the case that when a galaxy and an observer move apart, that the absorbtion lines within the spectrum are shifted toward the red end, and that this is the case regardless of whether the galaxy is moving away from us, the observer, or we from it, or each from the other?
As this red-shift can be seen exhibited by galaxies in all directions, at a rate that increases with distance, is it reasonable to suppose that the universe is expanding outward in all directions, and, if so, is this the current thinking? Silly perhaps, but I would like it answered please.
