Black hole interior from loop quantum gravity
In this paper we calculate modifications to the Schwarzschild solution by using a semiclassical analysis of loop quantum black hole. We obtain a metric inside the event horizon that coincides with the Schwarzschild solution near the horizon but that is substantially different at the Planck scale. In particular we obtain a bounce of the S sphere for a minimum value of the radius and that it is p...
متن کاملQuantum Gravity and Black Hole †
The quantum theory of the spherically symmetric gravity in 3+1 dimensions is investigated. The functional measures are explicitly evaluated and the physical state conditions are derived by using the technique developed in two dimensional quantum gravity. Then the new features which are not seen in ADM formalism come out. If κs > 0, where κs = (N − 27)/12π and N is the number of matter fields, a...
متن کاملBlack Hole Thermodynamics from Quantum Gravity ∗
The semiclassical approximation is studied on hypersurfaces approaching the union of future null infinity and the event horizon on a large class of four dimensional black hole backgrounds. Quantum fluctuations in the background geometry are shown to lead to a breakdown of the semiclassical approximation in these models. The boundary of the region where the semiclassical approximation breaks dow...
متن کاملLoop quantum gravity and black hole singularity
In this paper we summarize loop quantum gravity (LQG) and we show how ideas developed in LQG can solve the black hole singularity problem when applied to a minisuperspace model.
متن کاملCanonical quantum gravity and black-hole evaporation
Present approaches to quantum gravity remain so far inconclusive about the final stage of black-hole evaporation. The intention of this paper is to get a qualitative insight into how this stage may look like. For this purpose we address a simple model of two harmonic oscillators in the formalism of quantum geometrodynamics. One oscillator mimics the black hole state and is therefore attributed ...
