positron Posted July 19, 2005 Share Posted July 19, 2005 If the universe wasnt expanding, what will happen regarding a) red shifts in galaxy spectra b) the temperature of cosmic background radiation Link to comment Share on other sites More sharing options...
the tree Posted July 19, 2005 Share Posted July 19, 2005 To "a", there wouldn't be any as it is an affect of the universes expansion. To "b", I have no idea, I guess it wouldn't fade away nearly as quickly. Link to comment Share on other sites More sharing options...

DQW Posted July 22, 2005 Share Posted July 22, 2005 To "a", there wouldn't be any as it is an affect of the universes expansion.Why should a lack of expansion of the universe imply no relative motion between two galaxies ? Link to comment Share on other sites More sharing options...
danny8522003 Posted July 22, 2005 Share Posted July 22, 2005 It wouldnt. But there would be less redshifts and probably some more blueshifts too. Link to comment Share on other sites More sharing options...
DQW Posted July 22, 2005 Share Posted July 22, 2005 That would be a much better guess ! Link to comment Share on other sites More sharing options...
