Neutrino particle at CERN held to traveled faster than the speed of light

There has been much controversy about an experimental result at CERN that claims a neutrino particle travelled faster than light. Einstein's theory holds that this is impossible, but some dispute this. It's long been held that if the speed of light could be surpassed (by particles called "tachyons"), time travel would be possible.
