Can I hear sound in space?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: Why do we need to wear a space suit in space?; Why do things float around in space?; Why do stars twinkle? and more...

No, you cannot hear sound in space, as sound is a vibration. Any object can vibrate as vibration is just something moving back and forth. If it goes back and forth fast enough, it disturbs the air enough so that it moves through the air and gets to our ears. So, if you're in space, and something is vibrating and there's no air around, we can't hear it, because a sound is basically the vibration of something that vibrates the air and then our ears can pick it up. Without air in space, we can't have any sound.
