White Holes as Remnants: A Surprising Scenario for the End of a Black Hole
Eugenio Bianchi, Marios Christodoulou, Fabio D'Ambrosio +2
Quantum tunneling of a black hole into a white hole provides a model for the full life cycle of a black hole. The white hole acts as a long-lived remnant, solving the black-hole in…
How Information Crosses Schwarzschild's Central Singularity
Fabio D'Ambrosio, Carlo Rovelli
We study the natural extension of spacetime across Schwarzschild's central singularity and the behavior of the geodesics crossing it. Locality implies that this extension is indepe…
Characteristic Time Scales for the Geometry Transition of a Black Hole to a White Hole from Spinfoams
Marios Christodoulou, Fabio D'Ambrosio
Quantum fluctuations of the metric provide a decay mechanism for black holes, through a transition to a white hole geometry. Old perplexing results by Ambrus and Hájíček and more r…
