Understand

Recent attempts at the construction of holography for asymptotically flat spacetimes have taken two different routes.

Celestial holography, involving a two dimensional (2d) CFT dual to 4d Minkowski spacetime, has generated novel results in asymptotic symmetry and scattering amplitudes.
A different formulation, using Carrollian CFTs, has been principally used to provide some evidence for flat holography in lower dimensions.
Understanding of flatspace scattering has been lacking in the Carroll framework.
