Oh, by the way, the black hole threat from that particle collider is greater than thought
Rather, Roberto Casadio of the University of Bologna in Italy and Sergio Fabi and Benjamin Harms of the University of Alabama say mini black holes could exist for much longer — perhaps even more than a second, a relative eternity in particle colliders, where most objects decay much faster.
Under such long-lived conditions, it becomes a race between how fast a black hole can decay — and how fast it can gobble up matter to grow bigger and prevent itself from decaying.
“We conclude that … the growth of black holes to catastrophic size does not seem possible. Nonetheless, it remains true that the expected decay times are much longer (and possibly >> 1 second) than is typically predicted by other models,” the three state in a brief paper posted at the scientific discussion Web site ArXiv.org.
