If a systematic error enters there though, the fact of the precision of measurement with GPS, not disputed, would be a demonstration of the difference between accuracy and precision. "This is reinforcing the previous finding and ruling out some possible systematic errors which could have in principle been affecting it," said Antonio Ereditato of the Opera collaboration. Free. Furthermore, the pulses are quite long (10s), so an error in this analysis could easily be of the good order of magnitude. Was Aristarchus the first to propose heliocentrism? This means that the shift can only be detected statistically, and it makes the result extremely vulnerable to unanticipated systematic errors, e.g., correlations between the time of emission of the neutrinos and their energy (which strongly affects the efficiency of detection) or the direction of emission. Neutrinos might have mass, but their mass is so small that of all the ways the Universe has to create them, only the neutrinos made in the Big Bang itself should be moving slow compared to the speed of light today. Today, our mission remains the same: to empower people to evaluate the news and the world around them. Ask him to bet against the new results, though, and he says hed be willing to bet his house. At the same time B is in sync with C thru other paths with different lengths. Did the automated bot changing HTTP to HTTPS also inline the image, destroying the attribution/citation? I can assure you that the OPERA people are acutely and painfully aware of the long history of highly "significant" bumps just going away. And a cable can go bad if somebody hits it the wrong way with their butt while they are working in the electronics room. May be the case that this problem has to do with the one-way light speed and the referential that is used. the "missing time" is 62.5ns (compatible with 62.1 +/-3.7ns). But since they have mass, there is no reason that they couldnt travel at any speed. Free. Explore in 3D: The dazzling crown that makes a king. This doesn't seem right--- could a hardware problem actually do this? What's the cheapest way to buy out a sibling's share of our parents house if I have no cash and want to pay less than the appraised value? The neutrino was first proposed in 1930, when a special type of decay beta decay seemed to violate two of the most important conservation laws of all: the conservation of energy and the conservation of momentum. Speedy neutrino result may be due to instrument glitch, http://www.newscientist.com/blogs/shortsharpscience/2012/02/speedy-neutrino-result-may-be.html, Loose Cable Explains Faulty 'Faster-than-light' Neutrino Result, http://www.space.com/14654-error-faster-light-neutrinos.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+spaceheadlines+%28SPACE.com+Headline+Feed%29. Before the neutrino was known or detected, it appeared that both energy and momentum were not conserved in beta decays. The initial series of experiments, comprising 15,000 separate measurements spread out over three years, found that the neutrinos arrived 60 billionths of a second faster than light would have, travelling unimpeded over the same distance. It would mean that the antineutrino emitted by one nucleus could, hypothetically, be absorbed (as a neutrino) by the other nucleus, and youd be able to get a decay where: There are currently multiple experiments, including the MAJORANA experiment, looking specifically for this neutrinoless double beta decay.
