Black hole spin rate
WebMar 7, 2011 · When a rotating star collapses to become a black hole it continues spinning. The grey region, called the ergosphere, is where the hole's spin drags space in the direction of the hole's rotation so strongly that nothing can move counter to the spin. The black hole is spinning like a top, with the spin axis pointing upwards. [more] WebJun 30, 2024 · The prediction is therefore that the most massive black holes should be observed to have a wider range of spin rates than their less massive relatives. On the other hand, scientists expect...
