Gravity produces a force on a mass. A force is a vector that has both magnitude and direction. If the earth were flat, then the expected gravity vector would point wildly off vertical the further out towards the edge you went. It's hard to say exactly how bad the effect would be because FET doesn't seem to have any mass, exact shape, or density specs on the earth like RET does. To counter that UA was invented and under that paradigm everything is being accelerated at 9.81 worldwide. You can't really have any consistent change in the acceleration readings anywhere on the earth because that would mean that the earth would break up.
Some absolute gravimeters measure the acceleration of a small ball in a vacuum and use that figure for the gravity acceleration measurement. Those same instruments could function the same under UA. However, instruments consistently measure a change that depends upon latitude. You would expect that if the earth were an oblate spheroid. A small effect is also noticed due to the rotation of the earth (another FET no-no) and must be considered when calculating the gravitational acceleration.
So, either all the earth’s worldwide gravity surveys must be totally discredited as either being inaccurate, not done by competent personnel, not really measuring gravity, or the earth is really an oblate spheroid. An attempt has been made to cloud the issue and equate a seismometer reading with a gravimeter reading. Those two devices really measure different properties of the earth and are completely different things.
Of course, any mass, of any kind, will have a gravitational attraction to another mass, of any kind. As far as anyone knows, this is a universal fact and applies anywhere in the galaxy. It certainly applies anywhere in the solar system. The idea that the earth has mass and no gravity under FET is interesting. The Wiki still claims that tides are produced by the gravitational attraction of the moon and the stars. That would mean that the earth’s oceans have some gravitational attraction, but not the land or anything else. Another interesting ‘fact’.
There are inconsistencies all over the place, but FET and UA can fly if you just don’t look too close or ask too many questions. “Pay no attention to that little man behind the curtain”.
