General Relativity Singularities and Cosmogenesis
Vladimir N. Lukash, Astro Space Centre, Lebedev Physics Institute,

We discuss status of the singularity problem in GR and argue that the requirement that a physical solution must be completely free of singularities may be exaggeration. Assuming finiteness of Schwarzschild-like metrics we come to a class of geometries with integrable singularity that allows the effective matter to pass freely to the white-hole region. Connecting an astrophysical black hole to a white hole we come to astrogenic concept of generating new universes. This scenario essentially differs from other known mechanisms, such as bounce, baby-universe, birth from "nothing", etc.
