This paper is based on two insights: (1) that general relativity alone does not specify how much of the matter density contributes to the source term in Friedmann's equation, and how much contributes as the source of the gravitational potential of condensed objects; and (2) the source of the gravitational potential in the currently accepted cosmological model, for the small scales of condensed objects, is not what one would expect from Newtonian theory. Here insight (1) is used to restore the source of the gravitational potential to its Newtonian value, giving a new cosmological model. This model uses only conventional general relativity (no speculative physics) and the usual cosmological sources of gravitation, and there is no Hubble tension in this model if the total gravitational potential of condensed objects falls in a certain range. The deceleration parameter in the new model differs from that in the currently favored onel, suggesting a test to distinguish between the two models.

The case for a low dark matter density in dynamical dark energy model from local probes
A Bayesian combination of local probes shows that a low matter density can accommodate local H0 and sigma8 values in LCDM when the BAO sound horizon is left free, but dynamical dark energy still faces tensions with Pa...
