Description
Celestial holography proposes a duality between the gravitational S-matrix and correlators in a conformal field theory living on the celestial sphere. I will review some of the key features of this proposal, highlighting the importance of symmetries and discuss a few recent applications, including new insights into the gravitational phase space, scattering in non-perturbative backgrounds, connections to twistor theory and the flat space limit of AdS/CFT.
