How do you determine what is in direct contact with UA and what it is not?
Simplified answer (applicable for most things on the FE and most celestial objects; this list is also FOR dependent):
1. Is it accelerating at a minimum of 9.8m/s^2? Yes, go to #2. No, go to #5.
2. Is there an acceleration vector normal to the FE equal to #1? Yes, go to #3. No, go to #5.
3. When the object is not in contact with the FE (directly or otherwise) does the object retain the acceleration described in #1 and #2? Yes, go to #4. No, go to #5.
4. The object is affected by the UA (what I have termed Dark Energy).
5. The object is not affected by the UA/DE.
Ok, so:;
A) The part of the Earth near the equator, where the acceleration is below 9.8 (~9.78) is not affected by the UA.
B) The object accelerating at 10 m/s^2 but with tilted vector is not affected by the UA. That means, anything rotating around the Earth is not, because their vectors aren't normal.
C) Object accelerating in the opposite direction to the Earth can also be affected by the UA. So the UA can accelerate objects in two opposite directions.
D) If UA accelerates stuff at 9.8m/s^2, how is anything above the shield (see further part of the post) able to move with higher acceleration?
E) Anything outside of the Earth that is moving "slower" (lower acceleration) is not affected by the UA. Meteors that hit the surface for instance.
Etc. Your description makes no sense at all. It is very selective and basically causes 99.9999....9% of the Universe not to be affected by the UA.
If the disc acts as a shield to neglect the UA effect, why the Sun and the Moon do not fall onto the Earth? They are over the disc and UA is affected by the shield...
The FE creates a type of 'bow shock' within the DEF (Dark Energy Field). This prevents the objects on the top of the FE from being directly affected by the UA/DE. The field has nearly fully collapsed at about the altitude of the Sun and Moon, allowing for their suspension above the FE.
This "about the altitude of the Sun and Moon" collapse is so convinient that I just do not believe it. Also, the shiled would have to form a cylinder above the disc to ~map the reality. I find this hard to believe too.
Last question. Why the Earth is accelerating upwards so regularly (perfectly upwards), but there are plenty objects that are not?
Well, if the FE was not accelerating 'so regularly' we wouldn't be around to know it.
This answers the non-existing question. Try again.
