Spherical cosmological models: an alternative cosmology
  The properties of universes are explored that are entirely in the interior of
black holes. It is argued that these models offer a paradigm that may shed a
new light on old cosmological problems. The topics that are addressed include:
geometry of the universes, evolution, relation to the concordance model, dark
matter, dark energy, mass ejection from black holes, galaxy models with a
central black hole, Mach's principle.
