We investigate the interaction of intense light with matter: extreme conditions within a medium lead to the generation of remarkable bursts of rainbow light. Intense light can also induce an effective flow in the medium that can be used to create artificial event horizons and study spacetime geometries inspired by general relativity. Answering these questions leads to discoveries at the overlap between laser physics, quantum field theory, general relativity and photonic technologies.
