For more information on particles travelling 'faster than light', please research Cerenkov radiation. It is a nice shade of blue and very interesting.

Make note the particles never travel faster than c(theoretical tachyons exempted). It is the speed of light in a medium that slows down and allows the particles that are travelling very close to the speed of light to surpass their massless friends.
