The Clear Science staff knew you were going to ask that, lactose. Thank you! It all depends on what is doing the waving. Sound is a wave of air particles. And since there is no air in space, there can be no sound. (Other gases propagate sound as well, like helium and xenon. But there’s no gas at all in space.)
