Nutrino faster than loght disputed?
The announcement of opera team about the discovery of Nutrino faster than light vreated a futter in Science world.
Carlo Contaldi of Imperial College London says that it’s likely the OPERA team failed to take gravity into account in their equations and its effect on the clocks used to time the experiment. This because the degree of gravity at Italy and Geneva ,the two stations involved in the experiment were different. There for one of the clocks would have been running slightly faster than the other, resulting in faulty timing. .
Andrew Cohen and Sheldon Glashow, says that if the neutrinos in the study were in fact traveling as fast as claimed, they should have been radiating particles as they went, leaving behind a measurable trail; this due to the energy transfer that would occur between particles moving at different speeds. And since the OPERA team didn’t observe any such trail ,it follows that the neutrinos weren’t in fact traveling as fast as were claimed and the resultant speed measurements would have to be attributed to something else.Neither of these papers actually disproves the results found by the OPERA team of course, the first merely suggests there may be a problem with the way the measurements were taken, the second takes more of a “it can’t be true because of…” approach which only highlight the general disbelief in the physics community regarding the very possibility of anything, much less the speed of neutrinos traveling faster than the speed of light, messing with Einstein’s most basic theories. The first can be addressed rather easily by the OPERA team if it so desires, and the second, well, if the neutrinos did in fact travel faster than the speed of light and did so without leaving a trail, a lot of physics theory will have to be rethought. Though that may not necessarily be a bad thing, physics is supposed to be about finding answers to explain the natural world around us after all, even if it means going back to the drawing board now and then.
