A new discovery by Chinese scientists has puzzled experts. A monstrous black hole has been found on the other side of our galaxy – so large that, theoretically, "it should not even exist".
Called LB-1, this black hole is 15,000 light years from Earth and has a mass 70 times larger than the Sun, according to a study published in Nature magazine. The Milky Way is estimated to contain 100 million stellar black holes, but the new "monster" discovered is twice as large as anything scientists thought possible, said Liu Jifeng, a professor at the China National Astronomical Observatory, who said. led the research.
"Black holes of this mass should not even exist in our galaxy, according to most current models of stellar evolution," said Liu Jifeng. "LB-1 is twice as big as we thought possible. Now theorists will have to take on the challenge of explaining their background."
Two types of photography were used, three different programs and a lot of editing.
Scientists are now trying to understand how the LB-1 got so big. The Chinese team proposed a number of theories. One suggests that the size of the new black hole possibly "was not formed from the collapse of just one star." Instead, it could be two smaller black holes orbiting each other.
"This discovery compels us to reexamine our models of how stellar black holes form," said David Reitze, a professor at the University of Florida, director of the Laser Interferometer Gravitational Wave Observatory (LIGO).

As MSN News points out, recent studies of the LIGO and "Virgo" gravitational wave detectors have detected spacetime ripples caused by collisions of black holes that merge to create new and larger ones. But this is the first time a black hole of this magnitude has been discovered in the Milky Way.
"This remarkable result, coupled with the LIGO-Virgo detections of binary black hole collisions over the last four years, really point to a revival in our understanding of black hole astrophysics," said Reitze.
