Entropic Gravity| Entropic Gravity |
In General > s.a. dynamical triangulations;
emergent gravity; information theory.
* Idea: A proposal by
Verlinde in which space is emergent through a holographic scenario;
Gravity is explained as an entropic force caused by changes in the
information associated with the positions of material bodies.
* Two approaches:
Holographic gravity, in which Einstein's equation arises from keeping
entropy stationary in equilibrium under variations of the geometry and
quantum state of a small region, and thermodynamic gravity, in which
Einstein's equation emerges as a local equation of state from constraints
on the area of a dynamical lightsheet in a fixed spacetime background.
