Solving the Hubble Tension Using the PantheonPlusSH0ES Supernova Database

Making use of a CMB temperature formula derivable from the Stefan-Boltzmann law, we have discovered a duality between the Particle Data Group (PDG) CMB temperature of 2.7255K and its implied Hubble constant H_0 value of approximately 66.9 km/s/Mpc, which can be used to predict the 2287 observed supernova redshifts in the PantheonPlusSH0ES database. Both values of this duality fall within constraints set for these cosmological parameters by the Particle Data Group (PDG). Notably, because our solution requires a rigorous mathematical derivation of a cosmological distance-vs-redshift formula pertaining to a variant of the R_h = ct cosmology model, our supernova redshift-matching solution fits only within the H_0 constraints of the 2018 Planck Collaboration and the PDG. It is our conclusion that, by matching the entire PantheonPlusSH0ES dataset of 2287 observations with the Planck Collaboration H0 constraints, such a dataset ironically provides strong support for a H_0 value of H_0 = 66.8943+-0.0287 km/s/Mpc based on the Fixsen (2009) observation of T_0=2.72548+-0.00057K.
