Black Hole Interior from Loop Quantum Gravity

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 2 sphere for a minimum value of the radius and that it is possible to have another event horizon close to the r = 0 point.
