Generalized entropies and the expansion law of the universe

F. L. Dezaki B. Mirza

Abstrak

We suggest that using the first law of thermodynamics is a convenient method to obtain a correct form of the expansion law of the universe (Padmanabhan, arXiv:1206.4916v1 [hep-th]). We will, then, use this idea to obtain the expansion law for a Kodama observer. By using the expansion law for a Kodama observer, we can obtain the dynamic equation of the FRW universe for deformed Horava–Lifshitz gravity. The use of the first law of thermodynamics also leads to a new approach for obtaining the Friedmann equations for f(R) and scalar tensor gravities.
