General Relativity and Quantum Cosmology

Title: Interior metric and ray-tracing map in the firework black-to-white hole transition

Abstract: The possibility that a black hole could tunnel into to white hole has recently received attention. Here we present a metric that improves the "firework" metric: it describes the entire process and solves the Einstein's equations everywhere except on a small transition surface that corresponds to the quantum tunneling. We compute the corresponding ray-tracing map from past infinity to future infinity explicitly.
