I can't be the only person to ever have this thought so I am hoping one of you star gazers can tell me what I am missing. I understand Hubble's theory and the idea of space itself expanding. My question is this. If we know the universe is expanding because of the redshift and the farther away we look, the more red the spectra are shifted, doesn't that mean in the past, expansion was greater. Since the more distant light sources are older? Where do we conclude that expansion is accelerating because more distant galaxies were moving away faster when their light started towards us. Is it just the accepted conjecture or did I miss something. Seems to me the universe was expanding faster then and is slowing now. TBH I really can't base any conclusion about current expansion based on observations of what happened 10 billion years ago.
