Thanks for posting. On November 18 2011 15:16 Antisocialmunky wrote: I want to make a Mussolini made the neutrinos arrive on time joke but these results are very significant. I hope the tests at Fermi Lab and other places will really confirm this. Then we can look forward to many years of WHY IS THIS HAPPENING?!? | ||

It'll be years before they're done checking all the things they think it could be. | ||

It just means that their results are precise but its up in the air as whether they are accurate until it gets recreated. http://en.wikipedia.org/wiki/Accuracy_and_precision | ||

If this ends up being confirmed over the next few years, it means we can send messages back in time! | ||

Tommaso Dorigo, a physicist at CERN, noted on his blog that there are still other possible sources of error. For instance, the OPERA collaboration’s clock might not have a fine enough resolution to determine exactly when the neutrinos arrived. “The measurement therefore is only a ‘partial’ confirmation of the earlier result: It is consistent with it, but could be just as wrong as the other,” he wrote. Ultimately, the only thing that would convince many in the field is if another team upholds the findings in an independent experiment. Plunkett, co-spokesperson for the Main Injector Neutrino Oscillation Search (MINOS) experiment at Fermilab, says that his collaboration expects to have results checking the OPERA findings in the spring of 2012. http://www.wired.com/wiredscience/2011/11/neutrinos-screw-einstein/ | ||

In that case they must have some trick or loophole. There might be 7 spacial dimensions. Maybe neutrinos take shortcuts through dimensions unlike any other matter known so far. This is pure speculation just meant to give an idea. Yeah. I'm still at school, so I don't really know what I'm doing commenting in this thread, but I remember watching a TV programme about the neutrinos possibly travelling through something called the "bulk" (?), which was basically skipping through dimensions. | ||

Yeah bulk, but more normally called membrane I think. | ||

An international team of scientists in Italy studying the same neutrino particles colleagues say appear to have travelled faster than light rejected the startling finding this weekend, saying their tests had shown it must be wrong. They argue, on the basis of recently published studies by two top US physicists, that the neutrinos pumped down from CERN, near Geneva, should have lost most of their energy if they had travelled at even a tiny fraction faster than light. But in fact, the ICARUS scientists say, the neutrino beam as tested in their equipment registered an energy spectrum fully corresponding with what it should be for particles travelling at the speed of light and no more. http://tvnz.co.nz/technology-news/faster-than-light-particle-finding-refuted-4554490 | ||

If the neutrinos are indeed traveling faster than light, they've already broken all the rules, why would they also strictly adhere to this mass rule? | ||

The speed of light in a vacuum is a constant. However through other mediums light may travel significantly slower. For example in water light only travels at 75% of the speed of light in a vacuum. Matter is not limited by this same limit so can still travel up to 100% of the speed of light in a vacuum when it travels through water. This means that it is possible for matter to travel faster through certain mediums than light is able to travel. When this occurs Cherenkov radiation is released which reduces the energy of the matter. What the ICARUS scientists are implying is that when matter travels faster than light through a vacuum medium, there should also be a release of radiation (some analog to Cherenkov radiation). This would reduce the energy of the neutrinos received. I'm not sure how they can know for sure whether or not this radiation would actually occur. It seems to be extrapolating outside of the realms of known physics. The article explaining it is here: http://arxiv.org/abs/1109.6562 If this is true however, it implies that the neutrinos are spending most of their travel time at or below the speed of light. So either there is some source of error in the CERN experiment, or the neutrinos are jumping and traveling a short distance very quickly, then slowing down and traveling the rest of the way at or below the speed of light. | ||
