Description
Summary:De Sitter-Schwarzschild space-time is a globally regular spherically symmetric spacetime which is asymptotically de Sitter as r → 0 and asymptotically Schwarzschild as r → ∞. A source term in the Einstein equations smoothly connects de Sitter vacuum at the origin with Minkowski vacuum at infinity and corresponds to an anisotropic vacuum fluid defined by symmetry of its stress-energy tensor which is invariant under radial boosts. In the range of the mass parameter M ≥ M crit , de Sitter-Schwarzschild spacetime represents a vacuum nonsingular black hole, while M < M crit corresponds to a compact gravitationally bound vacuum object without horizons, called a G-lump. Masses of objects are related to both de Sitter vacuum trapped inside and to smooth breaking of the spacetime symmetry from the de Sitter group at the origin to the Poincaré group at infinity. We here present a geodesic survey of de Sitter-Schwarzschild spacetime.
