From Earth by scientists 55 million light years away from galaxy M87 It confirmed that the black hole photographed at its center was indeed rotating. This discovery was achieved by analyzing many years of observations.
Galaxy M87 from the Sun 6.5 billionIt contains a black hole r times larger. This black hole went down in history as the first black hole ever observed by humanity. In the latest study, it was determined that this black hole actually rotates and creates a jet stream around it in a certain period.
An international team of scientists reached this conclusion by examining 22 years of observational data from more than 20 telescopes. Analysis showed that the black hole at the center of galaxy M87 creates a jet stream every 11 years. This is definitive proof that the black hole is indeed rotating.
Black holes pull gas and dust into their surroundings with their enormous gravity. These particles do not fall into the black hole, and some are ejected into space at high speed in narrow beams. These events are called “jets”. The jet of the black hole in galaxy M87 oscillates by about 10 degrees every 11 years.
This discovery may be a consequence of Einstein’s Theory of General Relativity, which refers to so-called “frame drift” in which objects in space drift along the axis of rotation. This phenomenon indicates that the black hole’s spin creates a significant impact on the space-time around it, causing nearby objects to drift along the spin axis.
The rotation of the black hole in the M87 galaxy is thought to be associated with the accretion disk. Materials spinning in the accretion disk may not be aligned with the spin axis of the black hole, which can affect the formation of jets.
