I don't think anything has been shown to travel faster than the speed of light in a vacuum. The Special or General Theory of Relativity would require that any particle with mass cannot travel faster than the speed of light in a vacuum. There's an "imaginary" particle, called a tachyon, with no mass that exists only in theory (no experimental evidence for its existence) that travels faster than the speed of light. According to the Theory of Relativity, tachyons, from our frame of reference, would be traveling back in time.
