Reminds me a little of some bad science-fiction plots.
On September 10th, 3am (ET), the world's largest super-collider will fire up for its first shot. It will fire protons around a 17 mile circumference ring and smash them into each other . . .
. . . Just to see what happens.
One thing that could happen is the creation of microscopic Black Holes. Black Holes which could grow and devour the earth.
