Title: Complete Observable from covariant LQG: The Planck Star Tunneling time
Abstract:
Covariant LQG provides the machinery to define
probability amplitudes for transitions between 3D geometries via a path
integral over interpolating quantum spacetimes. An astrophysically
relevant probability is expected for the transition of a Black Hole to a
White Hole geometry. The setup for this calculation provides a concrete
example of how to use cov LQG and extract a complete observable from
the theory and how to deal with the "problem of time".
