Gravity Part 8
Wherein I will show how the Gravity Principle obeys Einstein's principle that the laws of Physics must not depend on the motion of the observer. This is called the Relativity of Motion.
First, I will briefly go over this principle of Relativity. Then I will summarize again the Gravity Principle (GP). Then I will show how GP obeys the principle of Relativity (of motion).
The Dirac Equation is Relativistically Invariant.
Proof attached.
Proving the Relativistic Energy-Momentum relation, the hard way and the easier way.
