特别新闻,欧洲原子能中心发现光速可被超越

大家都知道,“光速不可突破”在物理学里是什么样的地位哈。
  
  然后,今天CERN,也就是那个几年前差点撞出黑洞来的原子能中心,公布了他们的一个实验——
  
  在过去的三年里,他们重复了一万五千次实验,往730公里以外的地方发射粒子,然后得出了一个恐怖的结果:
  
  实验中发出的中微子,比光子跑得快了那么一丢丢~
  
  CERN的人知道这个事情大条了,内部研讨了很多次,但是找不出解释,所以今天下午,他们发布了一个Seminar,把实验公开了,请世界上的物理学家协助给出解释,或者发现实验的问题。
  
  呃,如果大家都解释不了,不得不承认那些中微子确实超了光速的话,会发生神马事情捏?
  
  大概会是,相对论内牛满面,量子力学内牛满面,世界上的物理学家一大半吐血满面吧……

  Puzzling results from Cern, home of the Large Hadron Collider, have confounded physicists because subatomic particles seem to have beaten the speed of light.
  
  Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away in Italy seemed to show up a tiny fraction of a second early.
  
  The results - which threaten to upend a century of physics - were put online for scrutiny by other scientists.
  
  In the meantime, the group says it is being very cautious about its claims.
  
  They will be discussing the result in detail in a conference at Cern on Friday afternoon, which can be viewed online.
  
  "We tried to find all possible explanations for this," said report author Antonio Ereditato of the Opera collaboration.
  
  "We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't," he told BBC News.
  
  "When you don't find anything, then you say 'Well, now I'm forced to go out and ask the community to scrutinise this.'"
  
  前面都是讲实验是怎么做的。比较吓人的是最后三句话。
  
  “我们尝试用各种可能的理论去解释。
  
  “我们想找个错来解释——小错大错,怎样都行。
  
  “最后什么也没找到,不得不公布出来,请大家一起来找茬。”
  
  呃,CERN好歹是欧洲最NB的原子能专家的集散地,如果他们都木有找出错……为毛我背上凉凉的……

可不可以这样理解

比如,以前看量子力学的书,都说粒子的运动是有概率性的,一个处于势井里的粒子,在能级没有达到足够高的时候,仍然有跃出势井的概率

那么,会不会一个粒子在接近光速的时候,也有超过光速的概率呢?而现在他们就观察到这个概率了。
