The fact is, the LHC could produce a tiny, extremely short-lived (read: harmless) black hole. It is an unlikely event, but one that physicists are nonetheless excited about. However, they discount the possibility of a stable black hole -- one with the chance to grow into something worth worrying about -- as much more science fiction than science.

Recently, two physicists took a close, practical look at the issue by examining known astrophysical phenomena, using what scientists already know about the universe to determine the likelihood that the LHC will produce stable black holes on Earth.

ut if the black hole was neutral, and if it was also stable, emitting no Hawking radiation, that could be troubling. Giddings and Mangano examine this scenario despite that the likelihood of it occurring is almost zero, since scientists believe that neutralization could not occur without the emission of Hawking radiation. Neutralization and Hawking radiation are intricately linked quantum processes; if one is occurring, the other should be, too.


Just take a look at the whole thing
