"Hawkins Radiation" happens over long, long time scales.
It does not happen in billionths of a second.
So the thermal radiation "observed" is NOT Hawkins radiation from a black hole.
On the other hand, I'm sure some alien civilizations in the universe are snuffed out once in a while when a physics experiment goes wrong.
Yepper..
I read all about it in a Marvel comic book..
Survivors tried to take over the earth, but they were only like, 1/8" tall..
A dog ate 'em..
For a normal type black hole (which are still theoretical, although there's reasonably good evidence for them now, but whether they actually contain a singularity or not is not know) containing the mass of at least several of our suns, Hawking (as in Stephen Hawking, who postulated this type of radiation) would take an extremely long time, probably longer than our universe has existed so far. However, for a singularity with a mass of only a few gold nuclei, or part of one, it could conceivably occur very quickly. This is way out on the fringes of theoretical physics, though, and quite possibly there is a simpler explanation. Pretty crazy stuff if true, though.
