简单的说,就是欧洲的科学家做实验发现粒子束跑得比光还要快;这下爱因斯坦完蛋了...
实验结果是由CERN的OPERA发现的(不是LHA,和对撞没关系)。由于实验的亚粒子是中
微子,中微子几乎不和任何物质产生作用,所以在真空和介质中的速度是一样的。
实验中的中微子是直接发射进入大地,穿过732公里之后被接收,测量到的速度与光速
的相对差别为(v - c)/c = 2.5 x 10e-5,也就是比光速快.0025%,或者说比光子早到
达目的地60纳秒,误差仅为+/-10纳秒。
目前费米实验室正在重现这个实验,这很可能是改变物理学基石的发现。
'We have broken speed of light' 22 Sep 2011
Antonio Ereditato, spokesman for the researchers, said: "We have high
confidence in our results. We have checked and rechecked for anything that
could have distorted our measurements but we found nothing.
"We now want colleagues to check them independently."
A total of 15,000 beams of neutrinos were fired over a period of 3 years
from CERN towards Gran Sassoin Italy, 730km (500 miles) away, where they
were picked up by giant detectors.
Light would have covered the distance in around 2.4 thousandths of a second,
but the neutrinos took 60 nanoseconds – or 60 billionths of a second –less
than light beams would have taken.
Scientists agree if the results are confirmed, that it would force a
fundamental rethink of the laws of physics.
John Ellis, a theoretical physicist at the European Organization for Nuclear
Research who was not involved in the experiment, said Einstein's theory
underlies "pretty much everything in modern physics".
The theory, which helps explain everything from black holes to the Big Bang,
"has worked perfectly up to now", he said.
According to the law that energy is equal to mass multiplied by the speed of
light squared, or E=mc2, firing an object faster than light would require
an infinite amount of energy.
Proof that something had travelled faster would pose major questions about
our understanding of the laws of nature because, for example, something that
travels faster than light would in theory arrive before it left.
