Rényi entropic corrections to cosmology are constrained by DESI DR2 BAO and GW data to a viable quintessence-like model that approaches ΛCDM without phantom behavior and satisfies BBN bounds.
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.
