In the wiki, it states from
https://wiki.tfes.org/Universal_Acceleration:
"In the FE universe, gravitation (not gravity) exists in other celestial bodies. The gravitational pull of the stars, for example, causes observable tidal effects on Earth.
Q: Why does gravity vary with altitude?
A: The moon and stars have a slight gravitational pull"
and
"Universal Acceleration (UA) is a theory of gravity in the Flat Earth Model. UA asserts that the Earth is accelerating 'upward' at a constant rate of 9.8m/s^2.
This produces the effect commonly referred to as "gravity"."
and from
https://wiki.tfes.org/Celestial_Gravitation:
"Celestial Gravitation is a part of some Flat Earth models which involve an attraction by all objects of mass on earth to the heavenly bodies. This is not the same as Gravity, since Celestial Gravitation does not imply an attraction between objects of mass on Earth. Celestial Gravitation accounts for tides and other gravimetric anomalies across the Earth's plane."
First, you acknowledge that CG is only part of some flat earth models. Yet, in UA, you imply its existence as a certainty. I think this is due to the known gravimetric anomalies that exist on earth (both FE and RE acknowledge this). However, it is shown that even though some anomalies exist due to high altitudes (which could be explained by CG), there are also anomalies that are dependent on rock density (which is how some mineral deposits are tracked and found). This is not explainable by UA or CG - in UA all objects on the surface of the Earth are accelerating at the same speed - so CG only accounting for altitude based anomalies cannot provide a full explanation of UA "gravity." Something else must exist. No matter what you can say about anomalies existing and going against the theory of RE gravity, you still cannot explain it by simply using UA and CG. Earth must either have its own CG, or gravity must exist.
Yet, contradictory to what you state elsewhere (that anomalies and CG exist), you also state: "Gravity appears to behave as if the earth is accelerating upwards, that there is no gravity gradient, and there are no other gravitating sources around us."
My premise is this: if other bodies of mass have CG, then earth has CG. Anomalies exist that cannot be explained by CG and UA alone. All of your above statements are contradictory or false.
