在校内看到，来这里散播一下谣言，顺便求考证
http://www.cbsnews.com/stories/2011/09/22/ap/tech/main20110301.shtml(AP) GENEVA — A fundamental pillar of physics — that nothing can go faster
than the speed of light — appears to be smashed by an oddball subatomic parti
cle that has apparently made a giant end run around Albert Einstein's theories
.
Scientists at the world's largest physics lab said Thursday they have clocked
neutrinos traveling faster than light. That's something that according to Eins
tein's 1905 special theory of relativity — the famous E (equals) mc2 equation
— just doesn't happen.
"The feeling that most people have is this can't be right, this can't be real,
" said James Gillies, a spokesman for the European Organization for Nuclear Re
search, or CERN, outside the Swiss city of Geneva.
Gillies told The Associated Press that the readings have so astounded research
ers that they are asking others to independently verify the measurements befor
e claiming an actual discovery.
"They are inviting the broader physics community to look at what they've done
and really scrutinize it in great detail, and ideally for someone elsewhere in
the world to repeat the measurements," he said Thursday.
Scientists at the competing Fermilab in Chicago have promised to start such wo
rk immediately.
"It's a shock," said Fermilab head theoretician Stephen Parke, who was not par
t of the research in Geneva. "It's going to cause us problems, no doubt about
that - if it's true."
The Chicago team had similar faster-than-light results in 2007, but those came
with a giant margin of error that undercut its scientific significance.
Outside scientists expressed skepticism at CERN's claim that the neutrinos —
one of the strangest well-known particles in physics — were observed smashing
past the cosmic speed barrier of 186,282 miles per second (299,792 kilometers
per second).
University of Maryland physics department chairman Drew Baden called it "a fly
ing carpet," something that was too fantastic to be believable.
CERN says a neutrino beam fired from a particle accelerator near Geneva to a l
ab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster tha
n the speed of light. Scientists calculated the margin of error at just 10 nan
oseconds, making the difference statistically significant. But given the enorm
ous implications of the find, they still spent months checking and rechecking
their results to make sure there was no flaws in the experiment.
"We have not found any instrumental effect that could explain the result of th
e measurement," said Antonio Ereditato, a physicist at the University of Bern,
Switzerland, who was involved in the experiment known as OPERA.
The CERN researchers are now looking to the United States and Japan to confirm
the results.
A similar neutrino experiment at Fermilab near Chicago would be capable of run
ning the tests, said Stavros Katsanevas, the deputy director of France's Natio
nal Institute for Nuclear and Particle Physics Research. The institute collabo
rated with Italy's Gran Sasso National Laboratory for the experiment at CERN.
Katsanevas said help could also come from the T2K experiment in Japan, though
that is currently on hold after the country's devastating March 11 earthquake
and tsunami.
Scientists agree if the results are confirmed, that it would force a fundament
al rethink of the laws of nature.
Einstein's special relativity theory that says energy equals mass times the sp
eed of light squared underlies "pretty much everything in modern physics," sai
d John Ellis, a theoretical physicist at CERN who was not involved in the expe
riment. "It has worked perfectly up until now."
He cautioned that the neutrino researchers would have to explain why similar r
esults weren't detected before, such as when an exploding star — or supernova
— was observed in 1987.
"This would be such a sensational discovery if it were true that one has to tr
eat it extremely carefully," said Ellis.
来个中文版的摘要
欧洲粒子物理实验室的科学家测量到了运动速度超过光速的亚原子粒子，如果发现得到
证实，将颠覆爱因斯坦的相对论即物理学界的基础。
中新网9月23日电 据外媒报道，欧洲粒子物理实验室的科学家22日声称，他们测量
到了运动速度超过光速的亚原子粒子，其运动速度是通过从日内瓦实验室向7百公里以外
的另一个实验室发射的微子中测到的。
科学家们表示对这个结果迷惑不解，对此持谨慎态度，并请求其他科学人士来证实
这一测量结果。因为如果他们的发现得到证实，将颠覆爱因斯坦的相对论里“光速超过
任何物质运动的速度”这一基本物理定律。
但该研究小组发言人安东尼奥·艾莱迪塔诺说：“我们对研究成果很有信心。我们
花了几个月时间，反复检验数据和设备，都没有发现任何错误。 ”
1905年，爱因斯坦提出的狭义相对论称，在真空环境中，宇宙中没有任何物质的运
动速度可以超过光速。这已经成为人们理解宇宙和时间的理论依据，同时也是现代物理
的理论基础之一。如果真的证实这种超光速现象，其意义十分重大，整个物理学理论体
系或许会因之重建。
嗯，其实超过光速意味着时间机器或者真有可能，看来CERN开始行动了。。。。
