In February, CERN said that the OPERA team were verifying a cable connection and a timing instrument called an oscillator that may have flawed measurements of the neutrinos' flight time. Rubbia added: "These are difficult and sensitive measurements to make and they underline the importance of the scientific process." This is how science works," said Bertolucci. "Whatever the result, the OPERA experiment has behaved with perfect scientific integrity in opening their measurement to broad scrutiny and inviting independent measurements. Knowing their findings would stir a storm, the OPERA team urged other physicists to carry out their own checks to corroborate or refute what had been seen.īut he and CERN Research Director Sergio Bertolucci stoutly defended the rights of scientists to make exceptional claims and to the rights of others to verify them. Instead, the particles were recorded as hitting the detectors in Italy 0.00000006 seconds sooner than expected. To do the trip, the neutrinos should have taken 0.0024 seconds. The neutrinos were timed at their departure from CERN's giant underground lab near Geneva and again, after travelling 732 km (454 miles) through the Earth's crust, at their arrival at the Gran Sasso Laboratory in Italy. The controversy began last September, when CERN's so-called OPERA team cautiously announced that sub-atomic particles called neutrinos had travelled some six kilometres (nearly four ) per second faster than the velocity of light, described by Einstein as the maximum speed in the cosmos. Their findings "indicate the neutrinos do not exceed the speed of light," the European Centre for Nuclear Research (CERN) said in a press release.ĬERN said last month there may have been technical hitches that had skewed the initial measurements, something that critics of the findings said they had always suspected. The new measurements were made by a team working independently from the scientists who had made the tentative but hugely controversial claim about "faster-than-light" particles. ![]()
