Why is almost everything squared in physics? as in 4πr², ψ², e², c²

Could the reason why so many equations in physics are squared represent aspects of a single truth based on just one geometrical process? The most famous of these equations is E=MC² Einstein’s energy equals mass times the speed of light squared and this is typical of physics equations that are squared. It is normally the speed of light and velocity that are squared. We also have the wave function of quantum mechanics squared ψ² and the electron e². This points very strongly towards one three dimensional 4πr² geometrical process that forms the Inverse Square Law! What is significant is that the inverse square law does not just apply to Newton’s universal law of gravitation it also applies to electric magnetic light or EMR. This video will put forward the idea that this is because gravity is a secondary force to electromagnetism with the whole of physics being based on one geometrical process.
