How fast does a black hole rotate
Web8 aug. 2024 · In this Universe, black holes have no choice but to rotate at extraordinary speeds. Perhaps someday, we’ll be able to measure that directly. Starts With A Bang is now on Forbes , and republished ... 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.
