Strange Particles May Travel Faster Than Light

This cosmic speed limit, 299,792,458 meters per second (about 700 million miles an hour), forms the backbone of Einstein's seminal Theory of Special Relativity, published in 1905. To rewrite this law would have broad-ranging implications, including even the possibility of time travel.

Could Einsteins theory finally be disproved?


Nothing goes faster than the speed of light. At least, we didn't think so.
New results from the CERN laboratory in Switzerland seem to break this cardinal rule of physics, calling into question one of the most trusted laws discovered by Albert Einstein.
Physicists have found that tiny particles called neutrinos are making a 454-mile (730-kilometer) underground trip faster than they should — more quickly, in fact, than light could do. If the results are confirmed, they could throw much of modern physics into upheaval.

The results come from the OPERA experiment, which sends sprays of neutrinos from CERN in Geneva to the INFN Gran Sasso Laboratory in Italy. After analyzing the results from 15,000 particles, it seems the neutrinos are crossing the distance at a velocity 20 parts per million faster than the speed of light.
By making use of advanced GPS systems and atomic clocks, the researchers were able to determine this speed to an accuracy of less than 10 nanoseconds (.00000001 seconds)
