I am wondering what density is required for a sound wave to travel at the speed of light (if possible at all!)
I'm not sure if there is a critical density at which a sound wave can go no faster.
Another related question is about 'cerenkov radiation': is it the same thing as light? That is, can we regard the waves of light to 'bunch up' in the same way as sound waves with a sonic boom?
