To answer your question: since the perceived rigidity of solid object is caused by electromagnetic interaction of its atoms or molecules, an impulse given to the object will propagate through it at the speed of light (or slightly slower). It cannot travel faster than the speed of light; in other words existence of a perfectly rigid body would have violated the theory of relativity.

I have deleted the page you have created; you could have asked the question at the reference desk. - Mike Rosoft (talk) 19:22, 10 December 2008 (UTC)
 * Lokks like I wasn't even right; apparently, the impulse would have travelled much slower, at a comparable speed to the speed of sound. - Mike Rosoft (talk) 19:27, 10 December 2008 (UTC)

Thank you very much, Mike! I appreciate your answer. (I tried wikianswers just now, but it does not let me post a question that long. I swear I wasn't trying to vandalize, CVU officer.)
