Abstract

We are demonstrating that the full SN Ia distance ladder can be matched simply by determining a single Hubble parameter, based on knowledge of the CMB photon density. We find that H0 = 66.8943±0.0295km/s/Mpc provides a perfect match to the full SN Ia distance ladder and resolves the Hubble tension.
