The black hole in their heads

So the new Cern collider will aim recreate conditions from the times closed to Big Bang and possibly even black holes and that made many people worried that the end of the world might come with this experiment. The Conservator Party from Romania even sent an open letter to some European institutions to stop the experiment :) The good news is that if a black hole is indeed produced they would not even feel when they will get past its horizon (the line that once passed you cannot escape the gravity of the the black hole). So we will not see them anymore!
