Abstract

We review our recent proposal to use certain spatial cross-sections of the boundary at infinity—light-cone cuts—to recover the conformal metric in the bulk. We discuss some extensions of this work, including how to obtain the conformal metric near the horizon of a collapsing black hole. We also show how to obtain the conformal factor under certain conditions.
