No. Sound is a sequence of pressure waves that propagate through a compressible medium, such as air or water. Sound has to move molecules in order to travel. Sound is transmitted from a source to the surrounding molecules, which vibrate or collide and pass the sound energy along until it eventually reaches our ears. The closer the molecules are to each other, the farther the sound can travel. This is why sound travels farther through water than it does through air and why it is impossible for sound to move through space. Continue reading →
