What scientists say about spinning of 'monster' black hole M87

Black holes, regions in space with gravity so intense that not even light can escape, have been a subject of intense study. By stitching together images from observatories worldwide, researchers discovered that the black hole's jets, streams of particles emanating from its axis, were in motion. This movement, detailed in a study published in the journal Nature on September 27, provided definitive evidence that the black hole was spinning.
