Black Holes Could Get So Humongous, Astronomers Came Up With a New Size Category
There are supermassive black holes. There are
ultramassive black holes. How large can these strange objects grow? Well, there could be something even bigger than ultramassive:
stupendously large black holes, according to the latest research.
Such hypothetical black holes - larger than 100 billion times the mass of the Sun - have been explored in a new paper which names them SLABs, an acronym that stands for Stupendously LArge Black holeS . We already know that black holes exist over a vast range of masses, with a supermassive black hole of 4 million solar masses residing at the centre of our own galaxy, explained astronomer Bernard Carr of Queen Mary University London.
