Is it possible that a big enough particle accelerator ,(the RHIC for example), could generate a black hole. If so - how?

Asked by: Tim Butler

Answer

I have just read the latest edition of New Scientist magazine which features a 4 page
article on the subject.According to the article, the smallest possible black hole is
about 10^{-35} meters across (Planck's Length). To create such an object by collision
would require energies of 10^{19} Giga-electronvolts - more than ten million billion
times the energies created by the RHIC. We would need a particle accelerator as big
as the galaxy to do it. Even then, this black hole would evaporate in about 10^{-42}
seconds. So, basically, the answer is no.
