"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. " - Black hole spin rate
