![]() I still feel that another experiment should make the measurement before I will say that I believe this result. From a theoretical point of view, it is not so appealing. That test will take another several months.Įven though he agreed to sign the paper, Stanco says: “I’m not so happy. The team is also trying to do the same test using another detector at the lab called RPC. They are still running other tests, including measuring the length of a fibre-optic cable that carries information from the underground lab at Gran Sasso to a data-collection centre on the surface. The team was planning to submit the paper to a European physics journal on Thursday. That was enough for Stanco to put his name to the paper, although he says six or seven team members are still holding out. What they found was “absolutely compatible” with the original announcement, he says. Some team members, including Stanco, had worried that the true error was larger. ![]() The team also rechecked their statistical analysis, confirming that the error on their measurements was indeed 10 nanoseconds. But Stanco says the tighter particle bunches made those hits easier to track and time: “So they are very powerful, these 20 events.” More checks In that time, they observed 20 new neutrino hits – a piddling number compared with the 16,000 hits in the original experiment. 100 of your electrons will be measured at. To double check, the team ran a second set of measurements with tighter bunches of particles from 21 October to 6 November. If your light is both energetic (high energy per photon) and intense (a large number of total photons), you won’t get an interference pattern at all. One of the main concerns was that it was difficult to link individual neutrino hits at Gran Sasso to the particles that left CERN. Its impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so. Only massless particles, including photons, which make up light, can travel at that speed. Stanco was one of 15 team members who did not sign the original preprint of the paper because they thought the results were too preliminary. Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). The result also unsettled those within the OPERA collaboration. Einstein’s theory of special relativity posits that nothing can travel faster than light, and many physicists believe the result could disappear in a puff of particles. Theorists have been struggling to reconcile the September result with the laws of physics. In quantum mechanics, virtual particles may travel faster than light, and this phenomenon is related to the fact that static field effects (which are mediated. Stanco is a member of the OPERA collaboration, which shocked the world in September with the announcement that the ghostly subatomic particles had arrived at the Gran Sasso mine in Italy about 60 nanoseconds faster than light speed from the CERN particle accelerator near Geneva, Switzerland, 730 kilometres away.
