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