'Mach c'? Scientists observe sound traveling faster than the speed of light

For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson’s team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.

I think the one thing that these types of experiments show is just how little we know about the physics that take place at a substantial fraction of C.
