At least not yetCMS Black Hole The Compact Muon Solenoid seen under construction in late 2008. Wikimedia Commons
Physicists working at the Large Hadron Collider report that after a series of tests, they have not seen any mini black holes, to the chagrin of string theorists and the relief of disaster theorists.
It seems a bit cynical to label people (such as myself) who are concerned about the consequences of theoretical physicists trying to mess with powerful forces they don't understand as 'disaster theorists'. It is one of the hallmarks of western science to seek to confuse the line between productive scientific discovery and hubris (in the Greek tragedy sense). I often wonder what the difference between religion and theoretical physics is (no offense to either) given how much each relies on faith and very minimal experiential evidence to so vehemently demonstrate the answer to the Jeopardy question 42.
But seriously, this LHC business reminds me of the words of the character Victor Frankenstein:
You seek for knowledge and wisdom, as I once did; and I ardently hope that the gratification of your wishes may not be a serpent to sting you, as mine has been.
