That will be the LHC's peak collision energy for 18�24 months before the collider shuts down in 2012 for a year of hardware repairs; only after that will CERN fire up the LHC at its design energy of 7 TeV per beam, producing 14-TeV collisions. But given how much physicists have learned from the much weaker Tevatron, even a half-strength LHC may have a chance to open up new realms of physics".

If the edge-case version of string theory that they're hoping to prove is right the black hole will be smaller than a proton. If Hawking is right, it'll evaporate before it has a chance to encounter any other matter. It's highly unlikely that the particular version of string theory that they're invoking will be right (it calls for the wrapped-up extra dimensions of string theory to be much bigger than most other string theories). And string theory itself is based on the same conclusions and logic that lead Hawking to deduce that black holes must evaporate -- so if the unlikely edge-case string theory that says these will happen is right, then the chances that Hawking radiation _won't_ take care of it is just about practically nil. OTOH, the chance that Magnetic is a raving lunatic or a troll is very high, and the fact that he's making terrorist threats against Geneva is absolutely uncontrovertible.
