Star turning into a black hole12/6/2023 It provides tantalising hints that that might be the case. “At some point in its history, something violent happened. (Dont fret: Our sun would need about 20 times its actual mass in order to turn into a black hole. “The fact that it’s spinning and there’s a tilt tells you that something pretty crazy happened in the past,” he said. The event, if we can prove it, could help us learn about. Younsi added that a black hole’s spin could, in future, give insights into the cataclysmic events that led to the formation of the supermassive black hole. Astronomers are trying to figure out if a star that vanished from view produced a black hole, almost before our eyes. It’s an indirect but extremely strong confirmation of spin.” These spaghettifying forces would distort your body into a noodle-like shape, causing you pain, loss of consciousness, death, and then your corpse would be atomized. A black hole can also form via the collapse of a neutron star into a black hole if the neutron star accretes so much material from a nearby companion star, or merges with the companion star that it gets pushed over the neutron star mass limit and collapses to become a black hole. When you slam another star into it, itll probably go nova, which is pretty destructive, but you can just keep tossing stars at them till you get lucky. If they have all that energy, just keep merging stars until you get a black hole. “Detecting this precession provides unequivocal evidence that the supermassive black hole in M87 is indeed spinning, thus enhancing our understanding of the nature of supermassive black holes,” the authors said.ĭr Ziri Younsi, an astrophysicist at UCL, said: “That’s exciting because it’s telling us that it can only precess if the black hole has non-zero spin. Dump several other stars into said black hole. ![]() This indicated a misalignment between the black hole’s spin axis and the accretion disk, leading the jet to wobble like a spinning top. This revealed a recurring 11-year cycle in the jet, which was found to precess around a central point at the edge of the black hole. The latest work, published in Nature, used observations of M87 from a global network of radio telescopes taken from 2000 to 2022. This winds up the field in a way that can accelerate particles away from the black hole as jets, extracting energy from the rotation of the black hole in the process. Scientists think that charged particles in the disk produce a powerful magnetic field and that as the black hole spins, it drags the field with it. Theoretical models suggest that the black hole’s spin is responsible for this phenomenon. Despite the enormous densities, the early universe didnt collapse into a black hole because, simply put, there was nothing to collapse into.
