Thermodynamics of Spacetime: The Einstein Equation of State arXiv:gr-qc/9504004v2

Thermodynamics of Spacetime: The Einstein Equation of State arXiv:gr-qc/9504004v2. The Einstein equation is derived from the proportionality of entropy and horizon area together with the fundamental relation ?Q = T dS connecting heat, entropy, and temperature. The key idea is to demand
