Scientists Not So Sure ‘Doomsday Machine’ Won’t Destroy World
By Paul Wagenseil
Still worried that the Large Hadron Collider will create a black hole that will destroy the Earth when it’s finally switched on this summer?
Um, well, you may have a point.
Three physicists have reexamined the math surrounding the creation of microscopic black holes in the Switzerland-based LHC, the world’s largest particle collider, and determined that they won’t simply evaporate in a millisecond as had previously been predicted.
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.
Casadio, Fabi and Harms think the black hole would lose out, and pass through the Earth or out of the atmosphere before it got to be a problem.
“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.
FoxNews.com can think of a few other things that didn’t seem possible once — the theory of continental drift, the fact that rocks fall from the sky, the notion that the Earth revolves around the sun, the idea that scientists could be horribly wrong.
We’re also wondering how often the LHC might create individual black holes, since longer-lived ones have a greater chance of merging with each other, and, um, well, see ya.
If the worst comes to pass, and there’s now a slightly greater chance that it might, at least it might explain why we’ve never heard from extraterrestrial civilizations: Maybe they built Large Hadron Colliders of their own.
