Gravity as an entropic force

From Wikipedia, the free encyclopedia

Verlinde's statistical description of gravity as an entropic force leads to the correct inverse square distance law of attraction between classical bodies.

The hypothesis of gravity being an entropic force has a history that goes back to research on black hole thermodynamics by Bekenstein andHawking in the mid-1970s. These studies suggest a deep connection between gravity and thermodynamics. In 1995 Jacobson demonstrated that the Einstein equations describing relativistic gravitation can be derived by combining general thermodynamic considerations with the equivalence principle.[1] Subsequently, other physicists have further explored the link between gravity and entropy.[2]

In 2009, Erik Verlinde disclosed a conceptual theory that describes gravity as an entropic force.[3] This theory combines the thermodynamic approach to gravity with Gerardus 't Hooft's holographic principle. If proven correct, gravity is not a fundamental interaction, but an emergent phenomenon which arises from the statistical behaviour of microscopic degrees of freedom encoded on a holographic screen.[4]

Verlinde's suggestion of gravity being an entropic phenomenon attracted considerable media[5][6] exposure, and led to immediate follow-up work in cosmology,[7][8] the dark energy hypothesis,[9] cosmological acceleration,[10][11] cosmological inflation,[12] and loop quantum gravity.[13] Also, a specific microscopic model has been proposed that indeed leads to entropic gravity emerging at large scales.[14]
