The Other Way Around: From Alternative Gravity to Entropy

Understand

Since the seminal work of Verlinde, the idea that gravity may be an emergent force of entropic origin has gained widespread attention.

• Many generalizations of this key idea have been considered in the literature, starting from well-known and well-motivated generalized entropies to derive generalized gravity theories.
• Here, we approach the problem from the opposite direction.
• We ask whether phenomenologically motivated generalized gravitational theories, yet lacking a strong theoretical justification, may find their origin in an entropic scenario.
