earthandwater.co - sound is only, and can only be interacted with through physics, just as light. On top of it, while light is defined within the realm of physics, sound IS physics. Just not in a way that we experience it sensory wise. Everything within our physical known universe is vibrating constantly and never ending.

One molecule vibrates individually, But next to another is where it gets interesting and how they interact, all via vibration. I feel like it’s fair to say that every vibrational wave is what we consider to be a sound wave. They’re the exact same thing we just can’t pick up on the frequency that it’s putting out externally. However physicists time and time again manipulate molecules with vibrational waves, so sound, to manipulate them.

For instance using sound and vibration you can make water hover. Vibrational waves are thrown off by everything in our natural known universe, sound is defined just as so, a vibrational wave. So I feel it safe to say that sound IS physics, light is experienced within the world we perceive around us because of continual vibrational waves.

Sound/vibration is the body of physics.
