Sorry, I did word it badly. But it is my understanding that the FE theory of "gravity" is due to the constant acceleration of the earth as caused by the big bang in one direction, this is the force in which we experience that keeps us from floating into space, ie "gravity".
However the RE theory of gravity is to do with the beleif that dense objects have some attractive force to them, I pulled this quote from Wikipedia "the strength of this field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body", which is basically just stating the density of large objects is what contributes to its so called "gravitational force", and all objects accelerate towards the centre of the earth.
Now out of these two theories, the one that can be proven with ease is the FE theory.
My question was basically about trying to prove the force of gravity exists, and why no one has produced a model to prove that gravity exists. For example, surely a beachball sized object of the same density as the earth should have the same relative attractive force on small objects.
