Despite all the vigilant posts of ‘TheEngineer’ in the manner: “Gravitation is acceleration”, one who keeps to oneself must admit that the current framework of FE Gravity simply has holes in it. The major inconsistencies are the following:
1) Objects near to the surface of the Earth fall when released, while celestial objects, such as the Sun and the Moon remain at the same relative altitude for very long periods of time;
2) The current FE model of gravity is not able to successfully explain the variation of the acceleration of free fall at different locations on the Earth and its decrease with altitude.
While there might be some other cases where FE Gravity fails, these two are sufficient to show you that there certainly is a problem with the theory. In my opinion, this is due to the fact that the model is based on the General Theory of Relativity, a theory developed with the RE model before its view at all times. Even though there might not be an explicit reference to the shape of the Earth, this is implicitly assumed. For example, since GR duplicates the results of the older theory of Universal Gravitation by Sir Isaac Newton for weak gravitational fields, it also admits the roundness of the Earth, since this is a common fact in the Newton’s theory.
So, the solution must be looked for in a new theory consistent with the FE model from the start and not relying on RE Theories. Otherwise, endless discussions with no conclusion are inevitable. But, mind you that the two greatest intellects in Physics, Newton and Einstein worked on these problems. So, unless you can compare your knowledge of facts and analytical powers with theirs, expect an impossible task.
