Abstract

In Verlinde’s formalism, gravity is an emergent phenomenon which can be interpreted as an entropic force. Borrowing the modified entropy-area relation from rainbow gravity, one can derive the corrections to the gravitational force from the viewpoint of entropic force. The modified gravitational force can be used to find the Friedmann equation in the Friedmann-Robertson-Walker (FRW) universe in the realm of high-energy physics.
