Seminarium Teorii Względności i Grawitacji

I will provide a survey into the notion of the emergent paradigm of gravity. It was shown by Jacobson, that one can derive the Einstein field equations from an equilibrium thermodynamic relationship implemented for local causal horizons estab-lished at a given point in spacetime. Later, it was shown by Padmanabhan that the Einstein field equations projected on a general null surface assume a thermodynamic interpretation analogous to the first law of thermodynamics for a certain physical process.Damour also showed that the field equations of general relativity on a null surface as-sume the dynamics which look structurally equivalent to Navier-Stokes equations. These strong interconnections between the gravitational field equations and the laws of thermodynamics and fluid flow form the basis of the emergent nature of gravity.
