To put it simply, can a shock wave move faster than the speed of sound? A lot of people seem to think so, and it might even be, but based on the wrong arguments. 'Sonic boom is caused when an object is travelling faster than the speed of sound' so the argument starts. OK, that is clearly the wrong start of an argument but the question is still a good one. I never studied fluid physics before, but my intuition suggests shock waves can move faster than the speed of sound but it soon reduces to speed of sound. To make the problem a little more specific, let's consider a stationary dynamite exploding.
