Faster than light neutrinos
September 24th 2011 14:48
In Albert Einstein special theory of relativity, there is a very interesting statement: the maximum speed of matter is light. Physicists now are actively looking for a single case faster than light. Neutrino is a good candidate as it is also massless and can travel long distance without interaction.
Is Albert Einstein Wrong?
Scientists at the Opera (Oscillation Project with Emulsion-tRacking Apparatus) experiment in Gran Sasso, Italy, found that the speed of neutrinos sent from CERN (at Geneva) is measured as 299,798,454 meters per second, while the speed of light in a vacuum is 299,792,458 meters per second. The neutrino speed is slightly higher than the speed of light in vacuum. Some theorists explain that the neutrinos may travel to extra dimensions and take a short cut, or special theory of relativity may be not fully correct.

On Thursday, the world's biggest physics lab unveiled a shocking finding: that one type of subatomic particle was clocked going faster than the speed of light. If true, it could undercut Einstein's theories. (Sept. 23)
