Neutrinos faster than light 20163/19/2023 ![]() Twenty "clean neutrino events" were detected at Gran Sasso, which the researchers claim were precisely associated with pulses leaving CERN. Those pulses were just 3 nanoseconds long, separated by gaps of up to 524 nanoseconds. In the more recent experiments, very short neutrino beam pulses were used in order to ensure precise measurements. While photons (light particles) had been repeatedly detected at Gran Sasso 2.4 milliseconds after leaving CERN, the neutrinos reportedly made the same trip in 60 nanoseconds less time. The original set of experiments consisted of generating a neutrino beam at the Geneva-based CERN particle accelerator, and shooting it 730 kilometers (454 miles) south to an underground laboratory in Gran Sasso, Italy. In the meantime, however, they've replicated those results themselves, and announced today that neutrinos still appear to be the speediest particles in the universe. To their credit, the OPERA collaborative made a point of inviting other scientists to try to replicate their results. Given that Einstein's special theory of relativity states that nothing can travel faster than the speed of light, their proclamation was naturally met with some skepticism - various physicists stated that there was likely a flaw in the design, implementation or calculations involved the experiment. ![]() On September 23rd, researchers from the European OPERA project made the now-famous announcement that they had observed neutrinos traveling faster than the speed of light.
