A discovery in the last week has turned physics on its head.
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.
The speed of light is a cornerstone in Einstein's theory of special relativity, which is what gives us the concept of causality: causes precede effects.
Among the implications of this challenge to mainstream 1 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 2 from the University of Surrey, Jim Al-Khalili, believes that the current consensus 3 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 4 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 5 shorts on live TV."
Quiz 小测验
1. What theory could be affected 6 by the new discovery?
Albert Einstein's theory of special relativity.
2. Does the new experiment prove the theory most physicists 7 believe?
No, it challenges mainstream theory.
3. What sci-fi activity could be possible if the new findings are correct?
Time travel.
4. Why does Jim Al-Khalili think the experiment is wrong?
He thinks that the researchers made a mistake with their methodology, the way they did the experiment.
5. Is the following statement true, false or not given? "Al-Khalili will challenge social conventions by eating his underwear on live TV."
Not given. Al-Khalili will only do this if the new Cern experiment proves to be true.
