Generation of Cosmological Flows in General Relativity (Features and Properties of Integrable Singularities)

Understand

We discuss status of the singularity problem in General Relativity and argue that the requirement that a physical solution must be completely free of singularities may be too strong.

• As an example, we consider properties of the integrable singularities and show that they represent light horizons separating T-regions of black and white holes.
• Connecting an astrophysical black hole to a white hole, they lead to a natural mechanism of generating new universes.
• Under favorable conditions the new universes will also contain black holes which, in their turn, will give rise to another generation of universes.
