Title: Black hole quantum mechanics and why it may affect the topologgy of space and time
Abstract
We explain how and why black holes emit particles in accordance with a unitary evolution law, demonstrating how to calculate the effects of this evolution law by using expansions in terms of spherical harmonics. It is found that the Einstein-Rosen bridge actually connects one hemisphere of the black hole with the other by means of an antipodal identification of points on the horizon. This way, we resolve the "black hole information paradox.
