A method to extract energy from a rotating one of these objects was proposed by Roger Penrose. These objects are completely characterized by their mass, charge, and angular momentum according to the no-hair theorem. They can be formed when a white dwarf exceeds the Chandrasekhar limit. The radius of these objects is smaller than their (*) Schwarzschild radius. They emit Hawking radiation, and supermassive ones are thought to lie at the center of galaxies. For 10 points, name these astronomical bodies with an event horizon, past which light cannot escape.
