Entropic Gravity

Entropic gravity is the conjecture, most prominently associated with Erik Verlinde (2011), that gravity is not a fundamental force but an entropic force arising from the holographic information storage capacity of spacetime. The claim draws on the holographic principle and black hole thermodynamics: if the information content of a region is bounded by its boundary area, then the tendency of information to distribute itself across available states produces an effective attraction that reproduces Newton's law and Einstein's field equations in appropriate limits.

The proposal is controversial. Critics argue that entropic gravity derives from thermodynamic analogies rather than first principles, and that it cannot account for quantum gravitational phenomena in regimes where the semiclassical approximation breaks down. Supporters counter that the same objections were leveled against statistical mechanics before its microscopic foundations were established.

If correct, entropic gravity would complete the historical trajectory by which gravity has been progressively demoted from fundamental force to geometric effect to statistical regularity — suggesting that the deepest structure of physics may be informational rather than dynamical.
