European researchers say they have measured the speed of neutrinos and found the subatomic particles do not travel faster than light.
The results appear to disprove another team’s measurements that astounded the science world last year by seeming to show neutrinos breaking the light speed barrier.
Nobel Prize winning physicist Carlo Rubbia says his team used a different experiment to trap neutrinos fired from the CERN laboratory in Switzerland to a detector hundreds of miles away in Italy.
Rubbia said Friday that his team’s measurements indicate there was something “not quite right with the results” of the rival group.
CERN said last month researchers found a flaw in the technical set-up that may explain the earlier experiment’s figures.
