Re: Supersonic problems

It's related to the fact that it's greater than the speed of sound. Not through causality though.

Basically, sound goes at that speed because that's the speed that air molecules bump into each other nicely. To go faster than that you have to move the air around you faster than it is comfortable going.

Think of it like driving through a traffic jam vs free-flowing traffic.
