BREAKING NEWS: Error Undoes Faster-Than-Light Neutrino Results

It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.

Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed. Many other physicists suspected that the result was due to some kind of error, given that it seems at odds with Einstein's special theory of relativity, which says nothing can travel faster than the speed of light. That theory has been vindicated by many experiments over the decades.

According to sources familiar with the experiment, the 60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer. After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed. Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.

这个新闻不算爆炸吧,要是查出来没错误,真的能超光速,那才是爆炸呢。。
相对论都要重写了。。

之前已然炸过一次了,现在发现炸过的东西安然无恙,算不算是又被雷炸了一遍?

呵呵,也是。

俺几乎都能感受到那几个科学家当初的激动心情,如果真能搞出超光速的东东,那就牛X大发了。。。
这辈子都不愁吃穿了,当然这是俺这种俗人的想法。

我也估计是智子眼红了,于是“不能便宜了这帮老兔崽子”哈哈哈

我觉得这种级别的科学家跟试验,出现这种错误很不可思议。。。。

估计当时通报实验结果的时候, 还没有做重复实验.
要么就是这个"bad connection" , 很好的, 不断重复着同样的实验结果~~~~
当时兴奋的估计什么都忘了.

就是那个建了几十年,耗资无数,始终无成果的加速器。如果再不炒作一下恐怕都被别人忘了。
我的观点,大爆炸理论从根上就是错的,现代天文学的路子走歪了,所以现在毫无成果可言。

意大利人做的东西你也能信? 意大利人就是欧洲的老中,很不靠谱的。Cern的实验很多,LHC和opera没关系的,LHC才是真正耗资巨大的实验,其耗费的金钱和广东的GDP差不多吧,从建造到现在运行,硬件不说,还要养着十几万博士博后做数据分析和模拟,今年要么就能找到higgs,到时全世界媒体包括ccav都要花至少一个月时间铺天盖地炒作,采访,做show,会很热闹的,伦敦奥运都会被忽视。但如果找不到,找不到的话这东西基本白建了,只能提出一些新的假说圆场,比如超大质量higgs或者其他什么sb不着边际的理论。粒子物理明显已经过了黄金时期了,现在做理论或者实验粒子的根本没有前途。而且以后除了中国,也不会有国家再投资更大型的实验了,现在他们财政都紧的很,这种纯粹为了解决人类好奇心的高能粒子实验不会再扩大下去了。现在年轻人要务实一点,做什么也别做粒子物理,喜欢物理的话做做材料什么的,比如量子计算量子通信,都比这种东西强很多。

怎么是“纯粹为了解决人类好奇心”呢?

这个观点我持保留态度,没有理论研究,没有“纯粹为了解决人类好奇心”,我们现在虽然不太可能继续茹毛饮血,但至少现代工业文明是绝对不会出现的

你这个观点不就是饱受抨击的“实用主义”、“有用主义”与“拜金主义”吗?
