Abstract: The main goal of Carrollian Holography is to offer a non-perturbative formulation of gravitational scattering theory in asymptotically flat spacetimes. This formulation relies on a correspondence between massless particle states and conformal fields locally defined at null infinity (the spacetime conformal boundary). I will review recent developments regarding this novel kind of « carrollian » CFT, and provide some evidence that it controls gravitational scattering amplitudes.
