Summary
Although there is little reason to discuss the CMB in relation to classical static models starting with Einstein’s model, a mid-2000s attempt by Sorrell deserves some attention and is discussed in the chapter. Motivated by the strong (perfect) cosmological principle of homogeneity and isotropy of the universe at all times, and drawing on the tired-light hypothesis of Crawford, Sorrell postulated a cosmic ether and a continuous nucleosynthesis that produces two kinds of particles composing it; we observe the resulting photons as the CMB. It is a toy-model with the goal of cautioning against an unconditional acceptance of orthodoxy.
