"Thermodynamic Origin of Einstein's Equations and the Null Energy Condition" |

A compelling idea in quantum gravity is that gravity is not in fact a fundamental force. Rather, in this view, gravity (and perhaps spacetime itself) is regarded as emerging from the coarse-graining of some as-yet-unidentified microscopic degrees of freedom. I will show that the first and second laws of thermodynamics, applied to the underlying degrees of freedom, give rise precisely to Einstein's equations and the null energy condition, respectively. |
