And that happens to be 299,792.458 kilometres per second. The discovery of Cherenkov radiation, that often causes a blue glow in nuclear reactors, led to the Nobel Prize in Physics in 1958. We all know the number one traffic rule of the universe nothing can travel faster than the speed of light. In fact, a charged particle passing through a dielectric faster than the speed of light leads to Cherenkov radiation. If this error is confirmed, the speed of light would reign supreme as the ultimate speed limit of the universe to the best of our knowledge. However, a particle can travel faster than the speed of light in a medium. The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster. Now, a blog on the website of the journal Science is reporting that a source from within the research group has identified a problem in their experiment that may have led to spurious results: a faulty fiber optic cable connection between a computer used in the experiment and a GPS unit involved in measuring the velocity of the neutrinos. Faster-than-light (also FTL, superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light ( c ). Reported in Inside Science News Service and many other news outlets around the world, the researchers said they announced the results to get the help of the international scientific community in evaluating whether there were any problems with the experiment. So what were their results The team came back and said that quantum entanglement transfers information at around 3-trillion meters per second or four orders. In September, researchers announced that they measured particles known as neutrinos traveling faster than the speed of light from the CERN accelerator in Switzerland to the Gran Sasso Laboratory in Italy. A signal cannot travel faster than light but in quantum mechanics. The second has to do with possible errors in the time stamping associated with neutrino-travel events in the experiment. What happens to one particle in an entangled pair determines what happens to the. UPDATE: February 22, 2012, 7:18 PM ET: Eugenie Samuel Reich provides additional information on Nature's newsblog, writing that the experimenters have identified two possible sources of error. UPDATE: February 23, 2012, 7:49 AM ET: CERN has issued a statement acknowledging two possible sources of error identified by the experimental team.
