The numbers are staggering--no, not even staggering, more like incomprehensible. When they start talking about half a billion light years from earth and a mass equivalent to a billion suns, one gets the impression that they're just making this stuff up.
No one can comprehend it, no matter how big-brained.
But according to the SRON Netherlands Institute for Space Research, that's the distance from Earth and the mass of a supermassive black hole that has been--get this--"kicked out" of its home galaxy and is now hurdling through space in search of a new home.
Come on, stop pretending that any of this computes. Kinda makes you feel puny, doesn't it? The heavens from time immemorial have lent themselves to just this sort of philosophical contemplation of human smallness.
