The Kerr metric is used for the spinning ones of these, while the Schwarzschild metric describes the non-spinning, uncharged ones.
Most X-ray binaries are thought to consist of one of these objects and an ordinary star. The Kerr metric is used for the spinning ones of these, while the Schwarzschild metric describes the non-spinning, uncharged ones. These objects, which usually form when gravitational force overcomes degeneracy pressure, can be completely characterized by their mass, charge, and spin, according to the no-hair theorem. The cosmic censorship hypothesis claims that these must always have event horizons to prevent their singularities from being visible. For 10 points, name these objects from which light cannot escape.
