How current CMB temperature related to cosmological redshift can be extracted from observations of 580 type Ia supernovae
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.
