Sakharov's induced gravity: a modern perspective

Abstract
Sakharov's 1967 notion of ``induced gravity'' is currently enjoying a significant resurgence. The basic idea, originally presented in a very brief 3-page paper with a total of 4 formulas, is that gravity is not ``fundamental'' in the sense of particle physics. Instead it was argued that gravity (general relativity) emerges from quantum field theory in roughly the same sense that hydrodynamics or continuum elasticity theory emerges from molecular physics. In this article I will translate the key ideas into modern language, and explain the various versions of Sakharov's idea currently on the market.
Maybe I should have been clearer! There is also a possibility for Gravity to be quantum without gravitons https://arxiv.org/abs/gr-qc/0204062 https://en.wikipedia.org/wiki/Induced_gravity https://en.wikipedia.org/wiki/Entropic_gravity However, for me to claim that quantum…
