Description
I will review some aspects of gravity in asymptotically flat spacetime and mention important challenges to obtain a holographic description in this framework. I will then present two important approaches towards flat space holography, namely Carrollian and celestial holography, and briefly explain how they are related to each other. Similarities and difference between flat and anti-de Sitter spacetimes will be emphasized throughout the talk.
