Extreme Power of Black Hole

Located at around 3.9 billion light years away from the Earth, black hole RX J1532.9+3021 was found to have extremely bright projections of x-rays. This means that the black hole is not only massive, but active. Astronomers used Nasa's Chandra Observatory to detect and measure the luminous source of X-rays, its mass determined to be around a quadrillion times the mass of the sun. The interesting thing about this black hole is that the hot glowing gas should cool down, and form trillion of stars as the gas expands. But this is not the case and no burst of star formations are detected. Astronomers have found two cavities in the gas and the super massive black hole is located in the center of the two cavities; where two supersonic jets are thought to be the cause of the 'drilling' of the gas. Effectively creating the cavities. Astronomers detected the jet using radio images and have found that no mater is falling into the black hole to account for the large X-ray sources. The only premise put forward that works is if the black hole is ultra massive. Such a black hole wouldn't require as much matter to fall into it to produce such jets. Another one, which also causes the black hole to be massive, is if it is spinning extremely rapidly. Information has also come in and there has been another cavity that has been detected but not aligned to the jets, and much older. This could suggest that the black hole is indeed spinning, and it is precessing. I personally wouldn't have guess that a black hole would precess, after all, isn't it a hole in the fabric of space? That would mean torsions in space could exist.
