Astronomers in England have discovered a supermassive black hole many times larger than should be possible.
In astrophysics, very few rules are hard and fast. There are mostly just loose parameters, theories and informed expectations -- expectations that are constantly being subverted by newly discovered phenomena.
That's what happened in England, where researchers at Keele University and the University of Central Lancashire had to throw their expectations out the window after measuring the impossibly large size of a black hole at the center of a newly discovered galaxy.
