Low-Energy String Theory Predicts Black Holes Hide a New Universe

Abstract

We propose a construction with which to resolve the black hole singularity and enable an anisotropic cosmology to emerge from the inside of the hole. The model relies on the addition of an S-brane to the effective action which describes the geometry of space-time. This space-like defect is located inside of the horizon on a surface where the Weyl curvature reaches a limiting value. We study how metric fluctuations evolve from the outside of the black hole to the beginning of the cosmological phase to the future of the S-brane. Our setup addresses i) the black hole singularity problem, ii) the cosmological singularity problem and iii) the information loss paradox since the outgoing Hawking radiation is entangled with the state inside the black hole which becomes the new universe.

Two-dimensional black holes in the limiting curvature theory of gravity

“…Such models allow one to solve the information loss problem [12] and give hints concerning the final stage of the black hole evaporation. In such models there exists an intriguing possibility of a new universe formation inside the black hole [13][14][15][16][17][18][19][20][21][22].…”
