Emergent General Relativity

Abstract

We review different approaches to quantum gravity in which spacetime is emerging. We discuss in some detail the proposals by G. Volovik and S. Lloyd and show how they differ in the way they treat time. We further propose an approach to quantum gravity in which the Einstein equations are derived rather then used. We call this approach Internal Relativity.
