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. WebHow fast are black holes rotating and how does that ro...
