Kenneth Chang in the New York Times:
According to one theoretical physicist, the collisions have even been creating a sort of tiny, short-lived black hole – very, very tiny and very, very short-lived. It lasts less than one-10,000,000,000,000,000,000,000th of a second.
And it’s not even really a black hole.
The black holes known to astronomers form when a star (or something larger) collapses and the gravitational pull grows so powerful that nothing can escape, not even light.
The Brookhaven mini-black hole, if it existed, would have nothing to do with gravity. Brookhaven’s Relativistic Heavy Ion Collider, RHIC (pronounced rick) for short, accelerates gold nuclei – atoms stripped of their surrounding clouds of electrons – to 99.995 percent of the speed of light and then slams them together, head-on.
