The collisions were powerful enough to break the nuclei into gluons and quarks, the most basic building blocks of matter. The particles created a plasma fireball 300 million times hotter than the surface of the sun. In a paper published on Cornell University's arxiv.org Web site, Nastase wrote that, based on his calculations, the fireball behaved like a black hole, absorbing streams of particles and radiating them as heat.

For now, any fears of the collider creating a civilization-destroying supergravity vortex are misplaced. The forces involved in the experiment were simply too weak, and the theoretical black hole was very short-lived. How brief? Divide a second by 10,000,000,000,000,000,000,000,000.
