Prove Physics: Teach yourself how to derive Physical laws from first principles

Since it was developed, Newton‘s law of gravitation and many other laws of physics cannot be derived from one grand underlying principle.

Deriving Newton‘s law of gravitation or Einstein general relativity theory, would mean that gravity emerges from something else and that would mean that the only known Newton‘s law of universal gravity is no longer a
fundamental law of physics.

Although this might be true, I believe that everything must have an origin. I believe that there is a fundamental u...
