Résumé

We will demonstrate that the formula proposed by Tatum et al. to predict the Cosmic Microwave Background (CMB) temperature in relation to observed (and theoretical) redshift fits the well-known formula T_t = T_0 (1 + z) , only when we have Beta= 0 or Beta = 1/2. Most importantly, we demonstrate how a rigorous mathematical approach can be used to extract a current CMB temperature of 2.726 ±0.072 K from the 580 type Ia supernova datapoints in the Union2 database. Using redshift formula z = Sqrt(R_H/R_t) −1 incorporated into our new “CMB redshift prediction formula,” we find that the above current CMB temperature value is a remarkably good match for this particular data set. We therefore predict the likelihood that this approach and the above current CMB temperature value will also produce a best fit with future observed type Ia supernova redshifts. If so, we think that there are also obvious implications for the optimal value of a CMB-derived Hubble constant. If all goes well, perhaps sometime in the not-too-distant future, cosmologists will treat the above CMB temperature method as a “gold standard” for future applications.
