Rotating Black Holeshole when the radius of the collapsing body becomes less than the gravitational radius. Suppose the collapsing body deviates considerably from spherical symmetry and/or its angular momentum and electromagnetic field are large. Will a black hole form? If it does, what will its properties be?

Physical Effects in the Gravitational Field of a Black Holelyzing the efficiency of energy extraction from black holes. Recall that although a black hole is by definition a region of no escape for material bodies and light rays, situations are possible in which energy can be extracted via certain physical processes. We will see later that this energy is ext
