The wave is actually just moving at the speed of sound. A few kilometers per second for very rigid materials.

What about a rotating rod where the inner part is being spun at the speed of light wouldnt the end of the rod have to be moving at greater than the speed of light? Any theory on what this would be like? What if the rod didn’t have to be accelerated to this speed but we imagined it springing to life as such spinning so that the linear speed of the close end was at C?
