Gravitational Vacuum Condensate Stars
A new final state of gravitational collapse is proposed. By extending the
concept of Bose-Einstein condensation to gravitational systems, a cold, dark,
compact object with an interior de Sitter condensate and
an exterior Schwarzschild geometry of arbitrary total mass is constructed.
These are separated by a shell with a small but finite proper thickness
of fluid with equation of state , replacing both the Schwarzschild and
de Sitter classical horizons. The new solution has no singularities, no event
horizons, and a global time. Its entropy is maximized under small fluctuations
and is given by the standard hydrodynamic entropy of the thin shell, which is
of order , instead of the Bekenstein-Hawking entropy
formula, . Hence unlike black holes, the
new solution is thermodynamically stable and has no information paradox.Comment: 17 pages, LaTeX fil
