摘要
It has been recently proposed that the gravitational interaction can be explained as an entropic force. Although a well defined fundamental description for such a mechanism is lacking, it is still possible to address the viability of phenomenological models of entropic-inspired modified gravities. I will summarize some recent work directed to using cosmology as a tool to constraint scenarios aimed to explain the physics behind dark energy and inflation. A phenomenological modification is able to explain cosmic acceleration at the background level and fit observations, but simple inflationary models with higher curvature corrections are incompatible with a matter dominated expansion era.
