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).
Proving the Relativistic Energy-Momentum relation, the hard way and the easier way.
This adds the proof for the relativistic mass effects from motion, proving that gravity causes it.
