Gravitational Vacuum Condensate Stars

Abstract

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 $p_{{}_V}=-{\rho }_{{}_V}$ and an exterior Schwarzschild geometry of arbitrary total mass $M$ is constructed. These are separated by a shell with a small but finite proper thickness $\ell$ of fluid with equation of state $p=+\rho$, 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 $k_{{}_B}\ell Mc/\hslash$, instead of the Bekenstein-Hawking entropy formula, $S_{{}_{BH}}=4\pi k_{{}_B}G{M}^2/\hslash c$. Hence unlike black holes, the new solution is thermodynamically stable and has no information paradox.
