Four such sources had been identified by 1964. ... although the maximum limit for a black hole's spin paramater is very slightly lower at a = 0.9982. At ... In late 2006, astronomers reported estimates of the spin rates of black holes in The Astrophysical Journal. A black hole in the Milky Way, GRS 1915+105, may rotate 1,150 times per second, approaching the theoretical upper limit. Relation with gamma ray bursts See more A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry.

WebAug 1, 2024 · While most stars themselves may spin relatively slowly, black holes rotate at nearly the speed of light. This might seem counterintuitive, but under the laws of physics, … WebFeb 27, 2013 · Einstein's theory predicts the faster a black hole spins, the closer the accretion disk lies to the black hole. The closer the accretion disk is, the more gravity from the black hole will warp X-ray light streaming off the disk. Astronomers look for these warping effects by analyzing X-ray light emitted by iron circulating in the accretion disk.
