Para você, que andava tranquilhinho:  como o Large Hadron Collider atrasou (por defeito em alguns dos magnetos do treco), o pessoal andou tendo tempo para fazer mais uns cálculos…e alguns físicos chegaram à conclusão de que os miniburacos negros criados pelo acelerador até podem durar alguns segundos.  Na Scientific American:

One corollary of the delayed start-up of theLarge Hadron Collider (LHC), the world’s largest particle accelerator, is that it gives physicists—and the rest of the world—more time to mull the much-discussed possibility that the LHC could produce Earth-gobbling black holes. 

In a paper posted recently to arxiv.org,physicist Roberto Casadio of the University of Bologna in Italy and his co-authors argue against such a scenario. But the bulk of the attention following their analysis has focused on their observation that microscopic LHC black holes, should they arise, could persist for seconds before decaying. (To wit, Fox News’s story headlined: “Scientists Not So Sure ‘Doomsday Machine’ Won’t Destroy World.”)” [grifo meu]

Pra nossa sorte, apenas algumas das várias teorias concorrentes predizem a formação de miniburacos negros pelo LHC.  Não é reconfortante?
