The hitch is that they would have imaginary masses, whatever that means. Technically, relativity does allow some particles, known as tachyons, to go faster than light in fact it forbids them to slow down to light speed. Einsteins theory is the basis of all modern physics, and has been tested a zillion times. The initial response of physicists assembled at CERN and around the world was that there was probably a mistake somewhere in the experiment. 23 in a paper and at a special symposium at CERN, the European Center for Nuclear Research, had beaten a metaphorical light beam from CERN to Gran Sasso, a distance of 457 miles, by 60 nanoseconds. The neutrino news came from a group of physicists based at the Gran Sasso underground laboratory in Italy and doing business under the apt acronym Opera. Under a YouTube video of the Corrigan Brothers (who played at President Obamas inauguration), one commenter observed: Irish Folk & particle physics what a combo. Example: We dont serve faster-than-light neutrinos here, said the bartender. Neutrino time-travel jokes have proliferated on the Internet. But that has not stopped the ghostly neutrinos, which can sail through miles of solid lead with impunity, from achieving a sort of pop culture fame not seen since 1960, when John Updike published a poem about them in The New Yorker: Physicists, who are quite sure that in fact E does still equal MC squared whatever may come of this experiment have expressed skepticism. Among other things, a neutrino or anything else that went faster than the speed of light could go backward in time. If they are right and the jury is still out Einstein might have some explaining to do. That, of course, is the cosmic speed limit declared in Albert Einsteins theory of special relativity in 1905. So asks the Irish band the Corrigan Brothers in a new song, Einstein and the Neutrinos, that is the latest rollicking riff on news that shocked the scientific world last month.Ī group of physicists from Italy claimed they had observed the subatomic particles called neutrinos traveling faster than the speed of light. Particles Faster Than the Speed of Light? Not So Fast, Some Say Since the NY Times is no longer free, I copy the article below.
I'll add some comments in my own reply later.
