Last month the European Center for Particle Physics (CERN) and the Italian laboratory of high-energy physics in Gran Sasso detected particles moving faster than light, what has been taken to be an impossibility for over a hundred years since Einstein published his theories in 1905. The particles found breaking this cosmic speed limit were neutrinos, bits of neutral matter so small that they can pass through people and planets unhindered, and so abundant that the nuclear reactions in the sun shower our planet with billions of them every second.
