First, I must stress that I am not asking this question in relation to the proof, or disproof, of any form of rotating Universe. I am only asking in order to understand the meaning of “homogeneity” in the cosmological context. Secondly, I know that there are many threads that reference homogeneity, some asked by myself, and I thank everyone for your previous comments and answers. However, I don’t think a question from this perspective has been addressed (or at least I couldn’t find it). Consider a model of the Universe, like a basic spiral galaxy (isotrophic, no blackholes, no other complications) – again, I am not suggesting that this model is valid, I just want to use the model to frame a question. From my God-like perspective I can see the centre of rotation and therefore I know that the model is not homogenous. However, if I reside within the model, at any point – centred or off-centre – I see the motion of other objects in the Universe relative to me, so things appear to rotate around me (kind-of-like Earth in pre-Copernican days), and so this is homogenous (I think). So my question is: which perspective is correct (in relation to the way the word homogenius is used in a cosmological context)? Thanks, in anticipation, for all your help, Noel.
