The apocalypse is still on, apparently,at least in a
galaxy about 3.5 billion light-years from here.
Astronomers reported that two supermassive
black holes appeared to be spiraling together
toward a cataclysmic collision.
The astronomers calculated, could releas0e as much energy as 100
million supernova explosions, mostly in the form of violent ripples in
space-time known.
Zoltan Haiman and David Schiminovich propose that most
of the light from the quasar is coming from a vast disk of
gas surrounding the smaller of the two black holes.
