A discovery in the last week has turned physics on its head. www.Examw.com
A team of scientists have said that they recorded subatomic particles called neutrinos travelling faster than light. No-one thought that was possible.
It is a finding that could overturn one of Einstein's long-accepted fundamental laws of the Universe.
The finding was made by researchers at Cern in Switzerland and Gran Sasso in Italy.
Among the implications of this challenge to mainstream theory is the fact that it could mean time travel is possible, a hypothesis that has long convinced writers of science fiction.
But the experiment has its sceptics. A physicist from the University of Surrey, Jim Al-Khalili, believes that the current consensus is correct and that the light-speed barrier is impossible to surpass.
He has tried to pick holes in the methodology of the Cern researchers. So sure is Al-Khalili that they have made an error in their measurements that he has decided to defend the laws of physics by challenging the laws of social convention.
Al-Khalili said: "If the Cern experiment proves to be correct... I will eat my boxer shorts on live TV."
