Lab fireball 'may be black hole'

"The Brown researcher thinks the particles are disappearing into the fireball's core and reappearing as thermal radiation, just as matter is thought to fall into a black hole and come out as 'Hawking' radiation."

This reminds me of David Brin's "Earth," in which a small artificial black hole escapes a lab and begins orbiting the planet's core. Gregory Benford uses a similar premise in "Artifact."
