Insights into gravitational physics derived from gauge theory perspectives.

Open questions remain about the full scope and limitations of the duality.

Abstract

We review the emergence of gravity from gauge theory in the context of AdS/CFT duality. We discuss the evidence for the duality, its lessons for gravitational physics, generalizations, and open questions.
