Accelerating scaling attractors where DM and barotropic fluid coexist at late times arise only for DM-density-controlled interactions with energy transfer from DM.
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.
Non-minimal effective scalar-tensor gravity supports early-universe bounce, inflation, and genesis while producing two Hubble values that could resolve the Hubble tension.
Gravitational lensing is recast as an optical phenomenon governed by effective refractive index, yielding closed-form deflection angles and Einstein radii for modified gravity models including deep-MOND, Yukawa, and power-law f(R).
Reviews the Layzer-Irvine equation and discusses its prior use in dark matter-dark energy interaction and modified gravity models while suggesting future directions.
