Black holes in loop quantum gravity
A Perez - Reports on Progress in Physics, 2017 - iopscience.iop.org
This is a review of results on black hole physics in the context of loop quantum gravity. The
key feature underlying these results is the discreteness of geometric quantities at the Planck …

Geometry of the black-to-white hole transition within a single asymptotic region
We write explicitly the complete Lorentzian metric of a singularity-free spacetime where a
black hole transitions into a white hole located in its same asymptotic region. In particular …

From black holes to white holes: a quantum gravitational, symmetric bounce
Recently, a consistent non-perturbative quantization of the Schwarzschild interior resulting
in a bounce from black hole to white hole geometry has been obtained by loop quantizing …
