No sound in space

Sound consists of small fluctuations in air pressure. We hear sound because these changes in air pressure produce fluctuating forces on various structures in our ears.

Sound has to travel as a vibration in some material such as air or water or even stone in able for us to hear it. Since space is essentially empty it cannot carry sound. Therefor there is no sound in space, at least not the sort of sound that we are used to.
