Abstract

Quantum gravity has the nature of being holographic, which enables us to learn about gravity from the boundary field theory. Although AdS/CFT is a very successful realization, it is still not clear how to generalize to general backgrounds, in particular the flat spacetime. In this talk, I will introduce some recent progress in understanding flat space scattering from the perspective of the boundary celestial sphere. This proposal goes under the name of celestial holography. I will focus on several aspects, including the rich symmetries, the close relationship with string theory, as well as some attempts along the line of bootstrap.
