♠️Sound is defined as disturbances or ‘vibrations’ that travel through a medium. It wouldn’t make sense for them to travel if there is no medium for it to travel through.

♠️Think about it. If you were in space, and you had a vibrating, say, cymbal in your hands, whywould your friend’s eardrum - a few meters away and with no contact to the cymbal - also start vibrating? It makes no sense. The only reason it happens on Earth is because the cymbal vibrating causes the air that it is touching to vibrate, and that air causes the air that it is touching to vibrate, and so on, until you get to the air that is inside your friend’s ear canal, which, by vibrating, causes your friend’s eardrum to vibrate, at which point they can hear the sound.
