Four experiments showed that neutrinos don’t move faster than the speed of light, providing evidence that an earlier measurement was inaccurate, according to the institute in charge of the research project.

Was Einstein wrong?

Measurements from four experiments taken at a laboratory in Gran Sasso, Italy, all showed neutrinos traveled in a time consistent with the speed of light, the European Organization for Nuclear Research, or CERN, said today in a statement.

CERN said in September a neutrino beam was measured in its Opera experiment traveling faster than the speed of light, appearing to break the cosmic speed limit described by Albert Einstein in his theory of relativity in 1905. The finding was probably flawed because of a technical malfunction in timing instruments, CERN said today.

“Although this result isn’t as exciting as some would have like, it is what we all expected deep down,” Sergio Bertolucci, CERN’s research director, said in the statement. “An unexpected result was put up for scrutiny, thoroughly investigated and resolved in part thanks to collaboration between normally competing experiments. That’s how science moves forward.”

The organization said in September it measured neutrinos, a type of subatomic particles, that were fired from CERN’s Geneva base to a laboratory 730 kilometers away in Gran Sasso traveling at a velocity 20 parts per million above the speed of light.
