Faster than light? Someone with a big brain can help?
RayB:
It's incredibly complex but I'm sure the people involved have thought of the obvious things, like rotation of the earth on its own axis and around the sun. Think about it, neutrinos pass through most matter, but the emitter and the receiving sensor are both stationary and moving with the earth. Once the neutrino is "launched", the position of the receiver is not a straight line, but a curve to account for it moving with the planet's axis and its orbit around the sun AND the solar system's movement within the galaxy AND.... That's quite the complex equation so I am in the "there's been a calculation error somewhere" camp.

Neutrinos, huh? So those hot rodding teenagers from Dimension X in the 80's TMNT cartoon broke the speed of light?

Hmm.. So the earth revolves around the sun at 28.9 km/sec, or 28.9 m/ms...
From Phil Plait:
--- Quote ---The distance from the detector in Italy to the source in Geneva is about 730 km. The travel time at the speed of light is about 2.43 milliseconds, and the neutrinos appear to have outraced that speed by 60 nanoseconds.

--- Quote ---The thing to do is to look at where this claim might have gone awry. First, the timing is interesting. They claim a measuring accuracy of 10 nanoseconds, so 60 ns would be pretty significant. However, my first thought is that light travels about 30 centimeters in 1 ns, so they need to know the distance between the source and the detector to an accuracy of 3 meters. If they are off by 20 meters, then we’re done; that would explain the difference entirely. I suppose this depends on how they measured the distance and the speed of the particles, too.

So the earth moved somewhere around around 70.2 meters in the period of time it took for the particles to travel the 730km. I'm guessing for that much movement, the neutrinos must have the velocity in that direction added to by the movement of the earth, wouldn't it miss the detector, otherwise?

HAHAHA I was waiting for someone to mention this! I was going to have to do it myself, if good ol Vigo didnt do it before me! Good job! :cheers: :applaud:

Shame to see educated people waste so much time studying things that will do absolutely nothing to improve our situation in the real world.

It's true science has never produced anything useful.
