    That fragile?
    Hmm but I'm not sure if they have confirmed the result with independent tests.

    I wonder if the neutrinos will get a speeding ticket?

    No, there is no law for that yet.

    Yes there is: E=MC^2. That formula breaks down when a particle/matter exceeds the "cosmic speed limit." icon_wink.gif

    nah they didn't break the speed of light

    "Immediately after OPERA first announced its result two months ago, physicists Andrew Cohen and Sheldon Glashow at Boston University argued that radiation analogous to Cherenkov radiation, but tailored to the case of neutrinos rather than charged particles, ought to have been emanating from the neutrino beam studied at LNGS."

    I just find it amusing that the physicist's name is Sheldon. I can totally see the glee on Sheldon Cooper's face if he were writing that party-pooping argument.

    As for the argument itself, all I want to say is that ultimately experiment trumps theory. If the faster than light measurements are borne out, just add the Standard Model of particle physics to the large heap of physical theories that need be revised. It's not surprising though, since Einstein's relativity is deeply imbedded into the Standard Model.

    There are just so many things wrong with these measurements, though. One of the biggest problems is that the machines used in these high energy experiments are calibrated according to the theory of general relativity and its famous postulate - that nothing can move faster than speed c. Essentially, saying these measurements are true means the particle accelerator has "disproved" itself.

    So now we can travel in Subspace. Awesome. Warp Factor 9, please.

    that formula is comepletely irrelevant to this situation! XD that formula is for nuclear reactions to calculate how much energy is created. but there is a formula for the former "cosmic speed limit"

    google the time dilation formula, seeing as im too lazy to continue typing XD

    I think you're talking about applying the lorentz transformations. But one can use that formula for the neutrino experiment because they consider the initial and final energies.

    didnt they measure the speed of the neutrinos by having a detector at a distance and measuring the time it takes to reach the detector though? because i dont see how E=mc2 factors in to this. a neutrino does not decay into other particles and has a standard (but highly debated) small mass which does not change therefore the equation E=mc2 is irrelevant in this case correct?
