Description

Modifications of gravity at early cosmological epochs are known to alleviate the Hubble tension better than late-time ones. The majority of such early-time Modified Gravity models affects the pre-recombination physics, and the Transitional Planck Mass (TPM) model makes no exception.
In this lightening talk I will briefly discuss the core idea behind this model, its intrinsic predisposition to mitigate both the $H_0$ and $S_8$ tensions, and future perspectives.
