Sucko CERN! Scotty was right!
That’s right! “You canno’ change the laws of physics!”
Einstein Proved Right in Retest of Neutrinos’ Speed
GENEVA (AP) — Einstein may have been right after all.
European researchers said Friday they had measured again the speed of a subatomic particle that a September experiment suggested traveled faster than the speed of light, violating Einstein’s special theory of relativity, which underlies much of modern physics.
The research team, led by the Nobel Prize-winning physicist Carlo Rubbia, found that the particles, neutrinos, do not travel faster than light.
Mr. Rubbia’s team, called Icarus, measured the speed of neutrinos fired from CERN, the European Organization for Nuclear Research, in Switzerland, to a detector 453 miles away in Italy.
“The results are very convincing,” Mr. Rubbia said, “and they tell us essentially that there was something not quite right with the results of Opera.”
Opera was the team that reported in September that its tests appeared to show neutrinos speeding faster than light, prompting widespread disbelief among scientists.
Einstein’s theory of relativity, a pillar of modern physics, says nothing in the universe can travel faster than the speed of light in a vacuum, approximately 186,282 miles per second.
That speed factors into all kinds of calculations, from estimates about the size and age of the universe to the radius of black holes.
Doubts about the Opera results were heightened last month when researchers said they had found a flaw in the technical setup that could have distorted the experiment’s figures.
Antonio Ereditato, a member of the Opera team and the head of the Albert Einstein Center for Fundamental Physics, said he welcomed the latest results.
“These results are in line with our recent findings about the possible misfunctioning of some of the components of our experimental setup,” he said.
Asked whether he was disappointed, he said: “This is the way science goes. What matters is the global progress of scientific knowledge.”
The Icarus team’s results came from a trial run for a longer experiment planned to take place in April or May. The Opera team, too, will repeat its experiment, this time with the technical glitches ironed out.
“The evidence is beginning to point toward the Opera result being an artifact of the measurement,” CERN’s research director, Sergio Bertolucci, said in a statement. “Whatever the result, the Opera experiment has behaved with perfect scientific integrity in opening their measurement to broad scrutiny.”
The Icarus team confirmed that, as Einstein predicted, neutrinos travel at the speed of light.
“I’m not displeased that Einstein was right again,” Mr. Rubbia said.
Mr. Rubbia says he is not displeased that Einstein was right again. But if Albert was alive today, I bet you he would be pulling this face at us all.
