abstract
We review some selected topics in celestial holography on the search for a celestial dual to quantum gravity in flat spacetimes. We focus on the bottom-up approach, emphasizing symmetries, key elements in celestial CFT, interplay with twistor theory, and connection to AdS/CFT.

A uniformly moving charge's field is a static Coulomb field in geodesic-centered coordinates, and in AdS the same construction yields a closed-form field with exact antipodal covariance whose null-fringe limits give flat-space antipodal matching.
