Ok, so here is my dilemma if thats how you spell it. So there is a Gong in space right, and lets say you hit it, does it even vibrate? No sound, of course, but does it still have the vibration necessary to make a sound? And if it does, does it go on indefinitely since and object in motion stays in motion unless acted upon? This is tricky i think, but maybe there is some simple answer. Please! I need peace from this!
