I will describe a new perspective on gravity in which the spacetime dynamics arises as an emergent phenomenon, like elasticity or gas dynamics. This approach explains several features of gravitational dynamics which have no explanation in the conventional approach and provides a conceptually coherent dynamical principle to derive the field equations. Einstein’s theory arises as the lowest order description (and is unique in 4 dimensions) with well-defined, calculable, higher order corrections in D>4. It turns out that this approach has important implications for quantum gravity as well as the cosmological constant problem.
