When we first realised that the further away a galaxy is the further towards the red side of the spectrum it was, we beleived this to be do to the expansion of the universe? Wouldn't it have been simplier to say that the further away a galaxy was the further the wave function stretched over space time? Just like in a pond? I know this is crazy as it would spell the end of current consmology. I just want to know why the second one didnt make more sense?
