Einstein was right gravity is a fictitious force and hence obeys F=ma. The proof

When we equate ma= GmM/r we get a= GM using this logic we can prove that gravitational acceleration does not depend on mass of the object and in order to do so we are equating the two equations so this proves Gravity is F=ma as per this logic.

Why am i breaking my head on a subject i am not a master of?

Do you realize that everything you are saying here was known to Galileo and Newton and has nothing to do with Einstein's theory?

From what you have written Hallsofivy i thought you are a fifth grader. See Stupid.

What was the basis of general relativity of Einstein? He observed that Fictitious force formula F=ma contains mass and also newtons formula contains mass so gravity must be a fictituous force but newton believed gravity to be an actual force due to the reason mentioned in my earlier thread.

Prove that newton and galileo knew gravity is a fictitious force. Give me links to the research papers or websites.

Clarification.

You didnt get the logic, why do i have to spoonfeed?

When you equate the two equation the mass of the object cancels out but the mass of the earth remains. Since it cancels out and we are left with only "a" from ma we infer that gravitational acceleration is independent of mass.

Whew you tired me!!!
