Whoa- - - Thats Heavy.
You must give Hawking a chance my friend. As well as Martin Rees, who is head of his dept. at Cambridge, Or Brian Green, author of "The Elegant Universe. It's quite obvious that black holes radiate energy thru quantum tunneling. This energy is recycled thru the universe. To claim "all" these gentelmen are wrong is "Quite Bold" to say the least. ---- to the point at hand; we already know at what aproximate energys these masses will be created. What will happen if that energy level is attained? All matter will begin pouring into the hole at the speed of light. No one at the facility will be aware of anything and unsuspecting victims in Asia will be consumed in about 8/10 of a second later, as the central point of the disturbance will accumulate mass equally from all points. It won't take the time to "Go Around The World."
To close things, What to do to prevent this disaster is a moot point. At the speed of light, you tell me, what are you going to have time to do? Heres one for you. You must admit that this endevour will not occure for a very,very long time. If by then we have mastered SuperString Theory then a time machine of sorts should be available. This device if intigrated into the hardware could be programed to take over, at the speed of light, to reverse the results before complition of the test. So there. What do you think? I just saved your Language Removed :). I say that with humor, hope you arn't offended.
