Theoretical scientific studies of black holes had predicted the existence of magnetic fields. Some monster black holes in the universe are predicted to keep on to increase up to potentially 1014 M☉ throughout the collapse of superclusters of galaxies. By fitting their motions to Keplerian orbits, the astronomers had been equipped to infer, in 1998, that a 2.6×106 M☉ item have to be contained in a volume with a radius of .
