>>The star's light beam that was supposedly deflected by the Sun’s gravity to add credibility to Einstein’s theory, was probably optically deflected by the Sun’s atmosphere as it passed through its extended corona.

No way. GR predicted the exact location of where the light would be perceived based on the measured location of the star behind the sun...repeatedly. FURTHERMORE, if the corona gases modified the path of light coming from something behind it, they would more likely cause the light from the distant star to reflect/refract away from the Earth entirely.

>>Secondary force exerts its force in succession, one body pushes against the next body which pushes against the next etc. etc.. A molecule pushes against the next molecule, an atom pushes against the next atom (even though, at this level they may not actually touching each other), the floor of a rocket pushes against the feet of an astronaut which pushes against his/her ankles which push against his/her legs etc. etc. It does not matter whether you are standing on the surface of earth or if you are accelerating in a rocket. The effect is the same - weight is created. Gravity, a Primary Force, exerts its force on all the atoms of a body simultaneously, not in succession

This is misleading as well. The "transference of force from one molecule to another" occurs whether the acceleration is caused by gravity or by rocket. Prime example: the "spaghetti-string" effect caused by black holes. (For those less knowledged, consider this example. Joe Schmoe is falling into a black hole feet-first. There is a point, very close to the center of the black hole at which gravity will pull harder on Mr. Schmoe's feet than it will on his head, thereby elongating his whole body. This force will elongate Mr. Schmoe until he is merely a long "spaghetti-string" of atoms/particles. That is, until he physically strikes the surface of the object at the center.)

Gravity is indeed acting on all particles of a human subject but not equally. It just seems so because Earth's gravity is so weak. If we were able to build many (seriously, I mean a LOT of) hypothetical atomic rockets that could propel each individual atom of a human subject, we could witness a secondary force with the same validity as (indeed, indistinguishable from) a primary gravitational force, simply because the force they would exert would be so weak.

Exemplifying that idea a bit further, let's take the idea of Mr. Schmoe in completely empty space, with little/no gravity to accelerate him, but equipped with atomic rockets to push all of his atoms in one direction. The tiny rockets would be his PRIMARY source of acceleration. If he were to approach, say, Earth, gravity would be the SECONDARY source of acceleration, and would affect him in exactly the same way as if the roles of the rockets and gravity were reversed.

>>Albert Einstein used his famous thought experiment to justify his "Principle of Eqivalence" postulate that asserts; Inertia (acceleration) and Gravity are equivalent.

Again, misleading. The above statement presumes that inertia and acceleration are the same thing. They are not. Inertia = the RESISTANCE to acceleration of an object due to its mass. Acceleration = Gravity. However, inertia != acceleration, ergo inertia != gravity. Basic Newtonian stuff.

Any questions?
