It's Official: Black Holes Have Lots Of Mass
KewlPC writes "Spaceflight Now reports in this article that some scientists have been able to measure the "weight" (yeah, yeah, it's actually mass, not weight) of a black hole that is (or was, 13 billion years ago) eating up the most distant known quasar, some 13 billion light years away."
Being one of the first posts, I have this sudden urge to make a perfect condidate for a -4 karma type of a post.. ehem.. to the matter however.. I'm wondering if any astronomy buffs could help me figure what does it help to know an approximate weight of a black hole? Other than an excuse to aquire more research dollars ;-)
