Title: |
Disappearance of the Black Hole Singularity in Quantum Gravity |
Abstract: |
We apply techniques introduced in quantum cosmology to the
Schwarzschild metric inside the horizon. The space-time inside
the horizon is the Kantowski-Sachs space-time with space section
of topology R x S^2. In particular, we use a mini-superspace
quantization procedure suggested by Loop Quantum Gravity and
based on an alternative to the Schroedinger representation. Using
this quantization procedure, we show that the black hole singularity
disappears and spacetime can be dynamically extended beyond the
classical singularity. At this point we introduce the matter and we study
the gravitational collapse of a star. We study the dynamic of the space
time in the interior of the Schwarzschild radius. In particular in our
simple
model we obtain the evolution of the matter inside the star and of the
gravity outside the region where the matter is present. When we impose
the boundary condition between the two region we identify an unique
time coordinate inside and outside the star.
