The question I have in this case concerns the third option. Would it be possible, in an infinitely sized and timed cosmos, to have a doppler redshift based on a change in space itself? On one hand, it seems contradictory -- how can everything be expanding in an infinitely large universe?
Actually, this was another question I wanted to get some feedback on. It doesn't seem easy to me to explain how the cosmological redshift could exist in an infinite universe.
I am not an expert in cosmology, but I don't think that expansion of space is compatible with an Universe infinite in size and in time.
