UA seems plausible, the model would explain what we observe in everyday life, at least for a while.
Question 1: The sun and moon seem to stay more or less the same distance per many FE models, thus they must be accelerating identically. Is there some structure that holds them up there? If the dome is holding them up, that would be some impressive structure. Or perhaps the same force that is accelerating the earth is acting on them but not airplanes.
Question 2: Do we have any reference outside the earth and astronomical objects that do not appear to be getting closer, thus must be accelerating as part of the earth/astronomical object system. Acceleration must be in relation to a point that is not accelerating, yet I see no info in FE on where that point is or how to observe it. My question is, can we observe or measure this acceleration from any frame of reference, or is the only way we know it is accelerating is by dropping things at the surface of the earth and attributing the acceleration of 32 feet/sec/sec to the earth rising instead of the object falling?
