(CNN) -- Scientists in Switzerland say an experiment appearsto show that tiny particles traveled faster than the speed of light -- a result that would seem to defy the laws of nature. The physicists say that neutrinos sent 730 kilometers (453.6 miles)underground between laboratories in Switzerland and Italy arrived a fraction of a second sooner than they should have, according to the speed of light.
The report was published Friday by a group ofresearchers working on the so-called Opera experiment, based at the European Organization for Nuclear Research, known as CERN, in Switzerland.CERN is the home of the Large Hadron Collider .

"I wassurprised, shocked," by the findings, Antonio Ereditato, Opera spokesman at the University of Bern in Switzerland, told CNN."However, we are confident in what we did and we think we did it correctly. "Weconcluded after a long scrutiny of all systematic uncertainties that we could not explain (the result) otherwise." The 150 or so researchers on the Opera project will continue their research, he said, butnow they want the worldwide scientific community to come up with "new ideas to explain or new experiments which should -- could -- confirm or disprove the effect."

The finding would seem tochallenge Albert Einstein's special theory of relativity, and the long-established law of physics that nothing can exceed the speed of light. "It is very, very remarkable if it's true," said ProfessorNeville Harnew, head of particle physics at Oxford University. "If this proves to be correct, then it will revolutionize physics as we know it."

He will beamong scientists from around the world tuning into a webcast seminar held by CERN Friday afternoon, to discuss what Harnew describes as an "ultra-exciting" development that has come "totally out of...
