    Second experiment confirms neutrinos travel faster than light

    The team behind the finding in September that neutrinos may travel faster than light has carried out an improved version of their experiment - and found the same result.
    If confirmed by other experiments, the find could undermine one of the basic principles of modern physics

    Insane!

    Honestly, it's too bad he isn't still alive. Imagine how much he could come up with considering the technology we have today.

    Re: Second experiment confirms neutrinos travel faster than light

    The possibility that these neutrinos really are travelling faster than light has been strengthened, although we cant confirm anything yet. If scientists fail to find any major criticism of this second experiment then we're looking at one of the basic pillars of our understanding of Physics come tumbling down. This wont just mean people in this field will have to change the way they view physics, but its literally going to have to involve rewriting most academic books, review current theories and open up many many new doors to us that we couldnt contemplate just a year ago.

    Not ONE OF the basic pillars. Causality is THE FUNDAMENTAL pillar. There's still a lot to be looked at. The fact of the matter is that this could be a material property. A while ago they had talked about light going faster than the speed of light through some material. The fact is that the photon wave packet could be detected apparently sooner than it should have been. But the phase information could not arrive faster than the speed of light. There was some interesting results of it and left hand chiral material tested; but it was all material property and interaction. Here they are shooting neutrinos through the earth, and there could be an effect as such.

    Want to do this right, you need a vacuum. If we had a cool Lunar Science Bay, we could aim the neutrinos there and know a hell of a lot better. It would be pretty difficult to drill a hole through the earth and evacuate the air.

    Re: Second experiment confirms neutrinos travel faster than light

    Before everyone gets too carried away, let's clarify what this second experiment did and didn't actually confirm. It did NOT confirm that neutrinos travel faster than light, it simply confirmed that whatever is causing the discrepancy wasn't due to a simple measurement error. If there is some systemic problem with the way the experiment was conducted, or if the experiment made an invalid assumption somewhere along the way, then it doesn't matter how many times you run the test and get the same result because the experiment itself is flawed.

    I remain highly skeptical of this result, and will continue to be skeptical until there is literally no other plausible explanation. Extraordinary claims require extraordinary evidence, as Carl Sagan famously said.

    Re: Second experiment confirms neutrinos travel faster than light

    This isn't a criticism, but a mere question to help me understand the concept. Is speed not relative? It seems to me that light itself would exceed C if the frame of reference were also moving in the opposite direction of that light, or at least would be measured to be higher. I always thought of C as a speed with the reference point being space itself (the grid points of the universe if you will), though maybe I'm missing some ideas from relativity. If the Earth were to move in the opposite direction of light through space, couldn't an observer then measure the speed of light to be higher than C relative to the earth?

    Re: Second experiment confirms neutrinos travel faster than light

    ok, so lets assume the experiments are correct, and faster than the speed of light is possible.

    what are all the ramifications?
