Recovering the spacetime metric from a holographic dual
Netta Engelhardt, Gary T. Horowitz
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 e…
New Insights into Quantum Gravity from Gauge/gravity Duality
Netta Engelhardt, Gary T. Horowitz
Using gauge/gravity duality, we deduce several nontrivial consequences of quantum gravity from simple properties of the dual field theory. These include: (1) a version of cosmic ce…
Evidence for an Electrifying Violation of Cosmic Censorship
Gary T. Horowitz, Jorge E. Santos, Benson Way
We present a plausible counterexample to cosmic censorship in four dimensional Einstein-Maxwell theory with asymptotically anti-de Sitter boundary conditions. Smooth initial data e…
Towards a Reconstruction of General Bulk Metrics
Netta Engelhardt, Gary T. Horowitz
We prove that the metric of a general holographic spacetime can be reconstructed (up to an overall conformal factor) from distinguished spatial slices - "light-cone cuts" - of the…
