An Albatross can fly around the world without landing, glide hundreds of miles at a time without flapping its wings (which span up to 12 feet), and travel at speeds of over 50 Mph.
According to physics, if a tree falls and no one is around to hear it, it still makes a sound. Sound is a mechanical wave of pressure and displacement through a medium such as air or water. We don’t have to perceive a sound to know the laws of physics are in play.
