Oops, just saw your post.
In any case, what this reporter wrote is basically incomprehesible.
"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.
