A New Physics Would Explain What Looks Like an Irreconcilable Tension Between the Values of Hubble Constants and Allows H₀ to be Calculated Theoretically Several Ways

Observing galaxies receding from each other, Hubble found the universe’s expansion in 1929. His law that gives the receding speed as a function of distance implies a factor called Hubble constant H₀.

In 2019, a cosmological model predicted a theoretical Hubble constant value of H₀ ≈ 72.09548580(32) km/(s*MParsec). This model someway also predicts what may look like two possible values of H₀. From this model, the none-approximated equation of the apparent age of the universe is about 14.14 billion years. With approximations, we get the well-known equation 1/₀ ≈ 13.56 billion years. We hypothesize that when we force these ages to fit the 1/H₀ formula, it gives two different H₀ values of about 69.2 and 72.1 km/(s*MParsec). This ambiguity explains what was looking like an irreconcilable tension between two H₀ values. With a theoretical correction factor of η ≈ 1.042516951 applied on the first value, both target the second value.

We measured H0 from the Cosmological Microwave Background (CMB) temperature T and the universal gravitational constant G: H₀ ≈ 72.06(90) km/(s*MParsec) from T by Cobra probe H₀ ≈ 71.95(50) km/(s*MParsec) from T by Partridge H₀ ≈ 72.086(36) km/(s*MParsec) from G H₀ ≈ 72.105(36) km/(s*MParsec) from G With 508 published values, we find a statistical value of about H₀ ≈ 72.0957±0.33 km/(s*MParsec) that validates our theoretical Hsub>0. Then, we find 42 equations linking Hsub>0 to different constants of the universe.
