Stephen Hawking: den nya partikelacceleratorn kommer inte att skapa ett nytt farligt svart hål på jorden

Stephen Hawking säger i en artikel i Newsweek att det inte är någon fara att den nya partikelacceleratorn i CERN - Large Hadron collider - kommer att skapa något farligt. Om den skapar något så görs det redan naturligt.

And it is absolutely safe. There has been a scare story that it might create a tiny black hole that would swallow up the Earth. But if the collisions in the LHC produced a micro black hole, and this is unlikely, it would just evaporate away again, producing a characteristic pattern of particles. Collisions at these and greater energies occur millions of times a day in the Earth's atmosphere, and nothing terrible happens. The world will not come to an end when the LHC turns on. The LHC is feeble compared with what goes on in the universe. If a disaster was going to happen, it would have happened already.
