How Recent Measures of H₀ Support the H₀ Estimate of the Haug-Tatum Hubble Tension Solution

In a series of recent papers, Haug and Tatum have suggested a way to resolve the Hubbletension within RH = ct cosmology. Based on the full distance ladder of Type Ia supernovae(SNe Ia), they find that the Hubble constant must be H0 = 66.8943±0.0287 km/s/Mpc. Thisvalue is close to the Planck Collaboration’s CMB-based estimate of 67.4 ±0.5 km/s/Mpc,except that their solution yields a much smaller uncertainty in the Hubble constant. TheSH0ES study by Riess et al., based on SNe Ia observations, gives a significantly higher value:H0 = 73.04 ±1.04 km/s/Mpc. The Hubble tension refers to the large discrepancy betweenthe H0 estimates obtained from the CMB method and those from SNe Ia data. Interestingly,recent JWST observations, when tied to SNe Ia, find H0 = 68.81 ±1.79. Thus, the JWSTresults lower the Hubble constant relative to the Riess study and appear to support the Haugand Tatum solution to the Hubble tension, a topic we discuss in this short note.
