Idiots guide to faster than light speed travel

  1. Jan 13, 2012 #1
    Dear Physicists,

    Do you know why there was a massive fuss made last year about the experiments at CERN which recorded neutrinos travelling faster than light speed?

    Do these results contradict any previous experiment?

    I hear a lot of talk about said results conflicting with the equations of special relativity. But i thought those equations merely implied a limiting speed for accelerating massive particles and didn't actually imply a universal speed limit.

    Do neutrinos have mass?

    Were the neutrinos in the CERN experiment fired from rest or were they merely channeled in the direction of the receiver?

    What speed does light actually travel at?

    Are there any contemporary definitions of the constant c which imply that c is actually a speed limit in the universe?

    Im confused.
