Neutrinos faster than light speed? What do you guys think?

    I feel like this is one of those things where they say "oh my god this will change physics forever" but it ends up being being incorrect. Either way it is odd that they would measure faster then light speed at all, I'll give them that. But 60 nanoseconds? Not quite enough to make me convinced. What do you guys think? There are so many reasons why this couldn't be true in the first place.

    I too am highly skeptical of the results, but not for the reason you state.

    How long would be enough to convince you?

    At light speed, 60 nanoseconds is a journey of epic length. Light can travel the breadth of your computer screen in that time.

    Yes I realize at lightspeed 60 nanoseconds means a lot of distance covered but its still too close to the "barrier" of lightspeed to come off as anything but an error in calculation or a malfunction. Were talking a fraction of a second here.

    Yes, a fraction of a second, which we are extremely good at taking measurements of despite what you think.

    Go watch the actual announcement from CERN ( http://cdsweb.cern.ch/record/1384486 ) before thinking they don't know what they're doing.

    The GPS system had an accuracy of only ±20 ns, among other things, including that no actual neutrino was clocked at FTL speeds.
