I will argue that if (i) entanglement entropy density across any surface is a universal finite constant η, and (ii) local Lorentz symmetry holds, then the spacetime metric must satisfy the Einstein equation, with Newton’s constant equal to 1/(4 hbar η). I will then discuss the nature of black hole entropy in light of this result.
