Scientists who announced that sub-atomic particles might be able to travel faster than light are to rerun their experiment in a different way. This will address criticisms and allow the physicists to shore up their analysis as much as possible before submitting it for publication.
Dr Sergio Bertolucci said it was vital not to “fool around” given the staggering implications of the result. So they are doing all they can to rule out more pedestrian explanations.
Physicists working on the Opera experiment announced the perplexing findings last month. Neutrinos sent through the ground from Cern (the home of the Large Hadron Collider) in Geneva toward the Gran Sasso laboratory 732km away in Italy seemed to show up a tiny fraction of a second earlier than light would have.
