Scientists have discovered a ‘monster’ black hole that’s so big it shouldn’t exist

(CNN)Scientists have discovered a “monster black hole” so massive that, in theory, it shouldn’t exist. “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, head of the team that made the discovery. “LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation.” Scientists are now scratching their heads at how LB-1 got so huge. The Chinese team has proposed a number of theories. LB-1’s sheer size suggests that it “was not formed from the collapse of only one star,” the study said — instead, it could potentially be two smaller black …
