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 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."

　　上周的一个重大发现彻底改变了物理学。

　　一些科学家表示，他们记录到一种叫做中微子的次原子粒子的速度超过光速。所有人都认为这是不可能的。

　　该发现可能会推翻长期以来为人们所接受的爱因斯坦关于宇宙的基本定律。

　　该现象是瑞士欧洲核子研究委员会和意大利的巨岩发现的。

　　光速是爱因斯坦狭义相对论的基石，为我们提供了因果关系的概念：原因先于结果出现。

　　对主流理论提出的其中一个挑战是，这意味着时光穿梭是可能的，该假设长期以来一直使科幻小说作家信服。

　　但是也有人怀疑这次实验。萨里大学物理学家Jim Al-Khalili相信现在的共识是正确的，光速障碍是不可能克服的。

　　他试图找出欧洲核子研究委员会这次实验的漏洞。Jim Al-Khalili确信科学家们在测量过程中犯了错误，他决定挑战社会管理法，捍卫物理学定律。

　　Jim Al-Khalili表示，“如果欧洲核子研究委员会的实验是正确的，我会在电视直播中吃掉我的拳击短裤。”
