Scientists discover 'monster black hole' so big it 'shouldn't exist'
Dec 02 2019
Scientists have proposed a few theories on how the LB-1 black hole was formed, but they do not align with what was widely perceived. But it's been agreed upon that stellar black holes are formed after supernova explosions, which occurs when massive stars burn out and die. Earlier, researchers had estimated that the maximum mass of a black hole could not exceed 20 times the mass of our sun, but LB-1 defies these beliefs.
"Black holes of such mass should not even exist in our galaxy, according to most current models of stellar evolution", saidLiu Jifeng, head of the team that made the discovery.
The large mass of LB-1 is known to be in the category of the 'pair-instability gap, ' and supernovas should not have produced it. "Now theorists will have to take on the challenge of explaining their formation".
Breaking all the understanding of black holes in Milky Way, a team of Chinese researchers has now discovered a huge black hole with a mass 70 times greater than the sun.
Some stellar black holes are detectable when they swallow gas from a companion star. Whereas a hit, this direction of restricted scientists' capability to search out more sunless holes since the overwhelming majority of them in our galaxy will no longer be actively drinking other stars.
Scientists found what they believe to be the first photo of a black hole back in April.
The results were nothing short of fantastic: a star eight times heavier than the Sun was seen orbiting a 70-solar-mass black hole, every 79 days. LAMOST enables researchers to detect black holes by first tracking stars that are orbiting something invisible to more than the naked eye, such as a black hole.
However, most of these bodies "are not engaged in a cosmic banquet", so only about two dozen galactic stellar black holes have been accurately identified and measured, the new study reported.
The monster black hole is located 15 thousand light-years from Earth. For example, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo gravitational-wave detectors have spotted ripples in space-time caused by the collision of black holes in distant galaxies, and these black holes are more massive than expected, according to the statement. "Therefore, they should not leave behind such a massive remnant", he explained.
LB-1 is not the biggest black hole ever discovered - but it may be the largest of its kind.
