An alternative theory of the universe as a finite sphere based on actual observations of Galactic redshifts and the cosmic microwave background. Mainline cosmological theories fail to explain Hubble's linear law best explained by a thermodynamic universe.Efforts to prove an expanding universe by seeking evidence proving non-linearity of Hubble's linear law beyond 3.96 bly as predicted by mainline theories is wasted time because theories themselves are non-linear much before that distance in violation of Hubble's linear law.
