ScienceDaily (June 30, 2008) — Particle colliders creating black holes that could devour the Earth. Sounds like a great Hollywood script. But, according to UC Santa Barbara Physics Professor Steve Giddings, it’s pure fiction.
Giddings has co-authored a paper documenting his study of the safety of microscopic black holes that might possibly be produced by the Large Hadron Collider (LHC), which is nearing completion in Europe. The paper, co-authored by Michelangelo Mangano of the European Center for Nuclear Research (CERN), which is building the world’s largest particle collider, investigates hypothesized behavior of tiny black holes that might be created by high-energy collisions in the CERN particle accelerator.
If they appear at all, these black holes would exist for “about a nano-nano-nanosecond,” Giddings said, adding that they would have no effect of consequence.”
That’s one billionth, of a billlionth, of a second for those of you wondering. What exactly is a black hole, or a micro-black hole anyway?
