According to this Reuters article, so say scientists. They shot neutrinos from CERN near Geneva to Gran Sasso Italy and the particles traveled the distance 60 nanoseconds faster than light would have.
Kinda interesting, I thought. Nothing I’m qualified to comment on though.
The speed of light can be exceeded by matter in special cases: Cherenkov radiation is one case where matter can travel faster than the phase velocity of light. But matter cannot exceed c of light.
WAG: it seems to imply neutrinos have no mass.
But Grey is right, one point on a Cartesian plot does not make for a line.
I saw this in the news today. As I was reading the article I said “hot damn!” out loud. Luckily nobody asked me why. I doubt anyone I was working with today would have understood why this might be a very big deal.
I heard it on the Today program (Radio 4 news) sandwiched between stories about evicting some travellers and Tories bitching about PPIs (don’t ask). Either this is a monumentally huge story which should eclipse every other piece of news, or it’s an experimental glitch, in which case it might make it into the inside pages of New Scientist. It was also (obviously) reported dumbed-down to the state of meaninglessness - “Einstein said that nothing can travel faster than light” sort of thing, not one mention of relativity as far as I recall. Certainly nothing to finesse a distinction between c and “the speed of light”. Wankers.
Anyhow, if neutrinos are travelling faster than light I blame the cats. Next on the today program…
Cats are weird.
Neutrinos are weird.
Therefore: cats cause neutrinos!
So if we mount a neutrino-shooter on a very long, very fast treadmill and shoot it backwards, will the neutrino just fall to the floor with a thud? And what if we turn the shooter around …
Absolutely. I was reading how they went over and over the results, checking and re-checking and re-doing the experiment over and over, before they published. And then they asked the other places that have the ability to run the same experiment to check their results.
We’ve already seen the xkcd comic on this. For another view of how to look at the world, here is today’s Non Sequitur comic (link may not be good after today).

This will probably turn out to be a really stupid mistake; their aim is off and the neutrinos are hitting the wall and bouncing back before they register them or the clock program is rounding down.
However I do agree it would be exciting if it does pan out. Quick, how can we build a spaceship out of neutrinos?
