      This sounds similar to Benford's COSM. What are some other stories about
      our universe being ina black hole?

      First few paragraphs

      Our own Universe may be the interior of a black hole existing in another
      universe.” In a remarkable paper about the nature of space and the origin of
      time, Nikodem Poplawski, a physicist at Indiana University, suggests that a
      small change to the theory of gravity implies that our Universe inherited its
      arrow of time from the black hole in which it was born.

      Poplawski says that the idea that black holes are the cosmic mothers of
      new universes is a natural consequence of a simple new assumption about the
      nature of spacetime. Poplawski points out that the standard derivation of
      general relativity takes no account of the intrinsic momentum of spin half
      particles. However there is another version of the theory, called the
      Einstein-Cartan-Kibble-Sciama theory of gravity, which does.

      This theory predicts that particles with half integer spin should
      interact, generating a tiny repulsive force called torsion. In ordinary
      circumstances, torsion is too small to have any effect. But when densities become much
      higher than those in nuclear matter, it becomes significant. In
      particular, says Poplawski, torsion prevents the formation of singularities inside a
      black hole.

      Astrophysicists have long known that our Universe is so big that it could
      not have reached its current size given the rate of expansion we see now.
      Instead, they believe it grew by many orders of magnitude in a fraction of a
      second after the Big Bang, the period known as inflation.

      Poplawski's approach immediately solves the inflation problem, saying that
      torsion caused this rapid inflation, which means the Universe as we see it
      today can be explained by a single theory of gravity without any
      additional assumptions about inflation.

      Another important corollary of Poplawski's approach is that it makes it
      possible for universes to be born inside the event horizons of certain kinds
      of black holes where torsion prevents the formation of a singularity but
      allows energy density to build up, which leads to the creation of particles
      on a massive scale via pair production, followed by the expansion of the new
      universe. "Such an expansion is not visible for observers outside the
      black hole, for whom the horizon's formation and all subsequent processes occur
      after infinite time," says Poplawski. For this reason, he emphasizes, the
      new universe is a separate branch of space time and evolves accordingly.

      Poplawski's theory also suggests an solution to why time seems to flow in
      one direction but not in the other, even though the laws of physics are
      time symmetric.

      Poplawski says the origin of the arrow of time comes from the asymmetry of
      the flow of matter into the black hole from the mother Universe. "The
      arrow of cosmic time of a universe inside a black hole would then be fixed by
      the time-asymmetric collapse of matter through the event horizon," he says.
      Translated, this means that our Universe inherited its arrow of time from
      its source. "Daughter universes," he says, "may inherit other properties
      from their mothers," implying that it may be possible to detect these
      properties, providing an experimental falsifiable proof of his idea.
