Physicist: Unfortunately, ultra small black holes straddle the line between quantum mechanics and general relativity, which makes it difficult to make useful predictions. If your conCERN is that the black hole thus created will destroy the world, you can relax. Second, the TeV (the energy an electron has after being pushed through 1,000,000,000,000 volts) collisions that CERN is aiming for happen in nature. So if we can form tiny black holes, then nature’s already beaten us to the punch. Do to the effects of Hawking radiation (which makes small black holes fizzle out and disappear), the scientists at CERN are working on methods to detect the secondary effects of a fresh black hole evaporating, instead of detecting the hole itself.
