Rotating black hole

A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry. A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry. There are four known, exact, black hole solutions to the Einstein field equations, which describe gravity in general relativity. Two of those rotate: the Kerr and Kerr–Newman black holes. It is generally believed that every black hole decays rapidly to a stable black hole; and, by the no-hair theorem, that (except for quantum fluctuations) stable black holes can be completely described at any moment in time by these eleven numbers:
