An extremely
massive blackhole. A hyper-
massive blackhole is larger than a supermassive blackhole and has the
mass of at least a trillion suns, (ie. hyper-supermassive blackhole. aka. stupendously large blackhole).
'Two supermassive blackholes merged to create a blackhole so supermassive that it became a hyper-supermassive blackhole, (ie. hypermassive blackhole ), but even that's
nothing compared to a
super-hypermassive, (ie. mega-hyper-supermassive) blackhole and so on.'
(Please read my
definition of a supermassive blackhole for more information).
