Solution of the H0 Tension — •Hans-Otto Carmesin — Gymnasium Athenaeum, Harsefelder Straße 40, 21680 Stade — Bahnhofstraße — Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen

In the standard model of cosmology, the Hubble constant should not vary as a function of the time.

However, when the Hubble constant H0 is measured, then probes that have been emitted at an earlier time or at a corresponding redshift z are used, and it turns out that the observed values of H0 depend on that redshift z, H0=H0(z,observation). That discrepancy is called H0 tension.

I derive a theory of dark energy, based on quantum physics and gravity. With my theory, I derive a term for the above function, H0(z,theory). That term is in precise accordance with observation, so my theory of the dark energy solves the H0 tension. I emphasize that the only numerical input used in my theory is the present day time after Big Bang combined with the universal constants G, c, kB and h.

Moreover, my theory solves various other fundamental problems of physics, see Carmesin, Hans-Otto (2021): Quanta of Spacetime Explain Observations, Dark Energy, Graviton and Nonlocality.
