Einstein's Equations From Entanglement

In recent years we have learned that the physics of quantum information plays a crucial role in the emergence of spacetime from microscopic degrees of freedom. I will review the idea that entanglement is the glue which holds spacetime together and show how Einstein's equations plausibly emerge from this perspective. One ubiquitous feature of these dynamical equations is the formation of black holes, so I will conclude by discussing some new ideas about the nature of spacetime inside a black hole.
