According to Einstein's special theory of relativity, light traveling in a vacuum is the universal speed limit. No information can travel faster than light.
But there's kind of a loophole. A short burst of light arrives as a sort of (usually) symmetric curve like a bell curve in statistics. The leading edge of that curve can't exceed the speed of light, but the main hump, the peak of the pulse, can be skewed forward or backward, arriving sooner or later than it normally would.
So that hump is moving faster than the speed of light. According to Einstein who tells us that nothing can travel faster than light and that of course means things can go faster than speed of light, because he puts things round the wrong way. Which is now the scientific method as per our Mr. Anonymous to say the opposite to what you mean. Bravo Mr. Einstein to initiate this scientific revolution.
