I think the following excerpt from Manton, Nicholas; Mee, Nicholas. The Physical World: An Inspirational Tour of Fundamental Physics explains it nicely:exander said:I was thinking about it a lot, and I am not sure how to explain cosmological red shift under conditions that just distance between comoving worldliness changes. How can this produce the effect of red shift? I always assume that the space in which the wave travels gets stretched.
