The idea of Verlinde that gravity is an entropic force caused by information changes associated with the positions of material bodies, is used in the present work for the FRW model of the Universe. Using modified Hawking temperature, the Friedmann equations are derived on any horizon. For the validity of the first law of thermodynamics (i.e., Clausius relation) it is found that there is modification of Bekenstein entropy on the horizon. However, using equipartition law of energy, Bekenstein entropy is recovered.

  1. On the entropy of the massive conformal gravity universe

    physics.gen-ph 2025-05 conditional novelty 4.0 of 10

    Total entropy in the open and flat massive conformal gravity universe grows with time, so those cosmologies pass the generalized second law; the closed one fails.
