Abstract: Numerous cosmological redshift formulae have been suggested in the field of cosmology. One of these is the well-known cosmological redshift formula used in the Λ-CDM model and in some R_h = ct models. In a recent type of “black hole” cosmology model, the redshift formula is derived from three fundamental principles: that the Stefan-Boltzmann law holds with respect to perfect and almost perfect black bodies; that the universe follows the R_h = ct principle; and that the time-dependent CMB temperature in relation to cosmological redshift is given by the observed relation T_t = T_0(1 + z). These three principles have recently been used by Haug and Tatum [1] to derive z = Sqrt(R_h/R_t) − 1, which has led to a simple but powerful solution to the Hubble tension [2–4]. This note highlights the importance of these three principles in relation to the new cosmological redshift formula and describes new ways to represent the same cosmological redshift formula.
