  ABSTRACT: 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. We want to validate our theoretical value of H0 ≈ 72.09548580(32) km⋅s-1⋅MParsec-1 with a new cosmological model found in 2019. This model predicts what may look like two possible values of H0. According to this model, the correct equation of the apparent age of the universe gives ~ 14.14 billion years. In approximation, we get the well-known equation 1/H0 ≈ 13.56 billion years. When we force these ages to fit the 1/H0 formula, it gives two different Hubble constant values of ~69.2 and 72.1 km⋅s-1⋅sdot;MParsec-1. When we apply a theoretical correction factor of η ≈ 1.042516951 on the first value, both target the second one. We found 42 equations of H0 linking different physics constants. Some are used to measure H0 as a function of the average temperature T of the Cosmological Microwave Background and the universal gravitational constant G: H0 ≈ 72.06(90) km⋅s-1⋅MParsec-1 from T by Cobra probe & Equation (16) H0 ≈ 71.95(50) km⋅s-1⋅MParsec-1 from T by Partridge & Equation (16) H0 ≈ 72.086(36) km⋅s-1⋅MParsec-1 from G & Equation (34) H0 ≈ 72.105(36) km⋅s-1⋅MParsec-1 from G & Equations (74), (75), or (76). With 508 published values, H0 ≈ 72.0957 ± 0.33 km⋅s-1⋅MParsec-1 seems to be the “ideal” statistical result. It validates our model and our theoretical H0 value which are useful to find various interactions with the different constants. Our model also explains the ambiguity between the different universe’s age measurements and seems to unlock a tension between two H0 values.
