Once considered rare and exotic objects, black holes are now known to exist throughout the Universe, with the largest and most massive found at the centres of the largest galaxies. These "ultra-massive" black holes have been shown to have masses upwards of one billion times that of our own Sun. Now, Priyamvada Natarajan, an associate professor of astronomy and physics at Yale University and a fellow at the Radcliffe Institute for Advanced Study, has shown that even the biggest of these gravitational monsters can't keep growing forever. Instead, they appear to curb their own growth - once they accumulate about 10 billion times the mass of the Sun.
These ultra-massive black holes, found at the centres of giant elliptical galaxies in huge galaxy clusters, are the biggest in the known Universe. Even the large black hole at the centre of our own Milky Way galaxy is thousands of times less massive than these behemoths.

Well, that was uncalled for. I'm scarred for life. I'm afraid I have to get out the big guns now...
