Generalized horizon entropy models satisfy BBN constraints on helium and deuterium abundances when parameters are chosen for cosmic acceleration, though lithium remains discrepant as in standard cosmology.
A van der Waals-inspired modification to general relativity renders the gravitational coupling dynamical, providing a mechanism to avoid Big Bang and black hole singularities.
A two-parameter extension of Bekenstein entropy is applied to derive the Friedmann equations and confirm thermodynamic consistency for an accelerating universe via entropy balance and maximization.
