So, looks like the limitation of c, the speed of light, has finally been broken, or observed as being broken, by scientists:
Scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertsons team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.
We also achieved what is known as a negative group velocity, a situation in which the peak of the output pulse exits the filter before the peak of the input pulse has reached the beginning of the filter, explained Robertson. Using the definition for speed as being equal to distance divided by time, we measured a negative time and thus realized a negative velocity.
It might not seem that a negative velocity would exceed the speed of light, but in this case, Robertson said, the speed of the pulse is actually much faster than c.

Guess they got fed up of being cllaed slow retards then. Maybe hyperdrive activates sometime soon then? *looks hopeful* *and sits to ponder the Mysteries of Sumeria, at Uruk...
