Another question to ask is the Large Hadron Collider even capable of producing micro black holes in the first place? Do the particles that collide at the LHC have the required amount of energy capable of even creating a miniature black hole in the first place?

This is quoted from Wikipedia: "It is believed that the smallest mass a black hole could have without quantum effects eliminating any such description is of the order of the Planck mass, which is about 2 × 10^-8 kg." If all of the energy of two colliding at 14TeV each is converted into micro black hole mass, this would result in a micro black hole with a mass on the order of negative 23 kilograms, which far below that of the Planck mass. Even a tillion particles colliding at the LHC once would not produce a micro black hole with a mass on order of the Planck mass. Because of this, it is very unlikely that the LHC will even produce a black hole.

Hawking Radiation is only a theory, but if true micro black holes created by the LHC would evaporate almost instantaneously. This is the arguement that you may have likely heard, or will hear from other sources as far as concerning the safety of the LHC

The bottom line is, there is no way a micro black hole produced by the Large Hardon Collider will consume the Earth in 2012. Sorry to you doomsayers, but take this one and throw it out the window. You don't need a unproven theory like Hawking Radiation to tell you this. Overall the final take on a micro black hole consuming the Earth in 2012...
