Description
The holographic principle suggests that quantum gravity can be described by an equivalent lower-dimensional field theory. While this idea is well-established in anti–de Sitter space, extending it to more realistic settings remains an open challenge. This talk presents recent progress toward a flat space hologram, where scattering amplitudes are expressed as correlators at null infinity. I will discuss how asymptotic symmetries guide a new framework linking infrared physics, quantum information, and the organization of scattering data, and outline key questions still to be resolved.
