Abstract
For almost twenty years there has been growing evidence for a “gauge/gravity” duality, in which a theory of gravity is equivalent to a nongravitational gauge theory. This duality is “holographic” since one can view the gauge theory as living on the boundary of space at infinity. I will first review this duality and some of the evidence for it. Then I will describe a new way to recover the spacetime metric from the dual gauge theory. This new approach is based on a special class of spacelike cross-sections of the boundary called light-cone cuts.
