Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of the matter in the cosmos is dark matter, much of it located in halos around galaxies. It was dubbed dark matter because it does not emit light, but it is also mysterious: it is not composed of atoms or their usual constituents like electrons and protons.

“Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,” said Liu Jifeng, astronomer at the National Astronomical Observatory of China and first author of a 2019 study of  a black hole known as LB-1,  discovered lurking at the far side of the Milky Way with a mass that is around 70 times larger than our sun with an orbiting blue monster, a star eight times the size of the sun.. “LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation.”
