Schwarzschild black hole
Extracted from the Wikipedia article Schwarzschild metric.
According to Birkhoff's theorem, the Schwarzschild metric is the most general spherically symmetricvacuum solution of the Einstein field equations. A Schwarzschild black hole or static black hole is a black hole that has neither electric charge nor angular momentum (non-rotating). A Schwarzschild black hole is described by the Schwarzschild metric, and cannot be distinguished from any other Schwarzschild black hole except by its mass.
