Explore the fascinating concept of emergent translation invariance within the framework of celestial holography in this 56-minute conference talk. Delve into advanced theoretical physics as the speaker examines how translation symmetries naturally arise in celestial holographic theories, bridging concepts from quantum field theory, general relativity, and holographic duality. Learn about the mathematical foundations underlying celestial amplitudes and their relationship to conformal field theories on the celestial sphere. Discover how asymptotic symmetries in gravitational theories manifest as emergent properties in the holographic description, and understand the implications for our comprehension of spacetime structure at infinity. Gain insights into cutting-edge research connecting scattering amplitudes, soft theorems, and the holographic principle in the context of flat space holography.
