WebThe orbital velocity closer to a black hole than 1.5 radii would be greater than the speed of light. Inside this radius, the faster you try to go, the less the centrifugal force you experience becomes, and so the faster you would fall towards the blackhole. In fact you won't find a stable orbit closer than 3 radii from the black hole.

Web9 apr. 2006 · If the black hole does not spin, then η is only 5.7 percent. However, the faster the black hole spins, the greater η is. For the fastest possible spin, η is 42 percent, which means that nearly half the infalling mass gets transformed into energy. Thus, a black hole can change matter into far more energy than a normal star can.
