To just get to near the speed of light would take an unimaginable amount of force
You all keep saying that as though the velocity means something. Do you have any evidence that the earth is being accelerated from an outside frame? If not, it's imaginable . Large, because the earth is large, but imaginable.
Also, the Orthodoxy full already full of un-imaginable large forces (from ANY frame). Do you believe the universe is expanding? That this expansion is accelerating? That the mystery energy needed to make Orthodox physics work is so monumentally large that if you took all the total mass in the universe, you'd need to multiply it's energy-equivalence by a dozen or so. E=mc^2, so we're talking about unimaginably large amounts of energy, right? I can scarcely fathom the total mass in the universe, let alone an unobservable energy-equivalence over 12 times as large. Are you prepared to reject the Orthodox model as "unimaginable" yet? Or are you applying different criteria for your beliefs and imaginings?
That sounds great except your UA model is not just accelerating the Earth. It is accelerating the entire Universe that we can see at least (however you want to define as existing or how much you want to deny, either way). Not only a velocity since with no friction everything would just keep moving the same velocity indefinitely, but with acceleration. In order to have continual acceleration the force applied to continue it has to increasing to keep accelerating. You talk of reference frames, as if that just brushes the issue away. What part of the Universe we can see wouldn’t be affected by your UA? Then come back and scoff as if the energy needed to make the entire visible Universe (however you want to define it) accelerate indefinitely (as far as we know).
Again, this UA fantasy also would have to create a spiraling force for all the objects in it to make them rotate around the Earth.
Again, how does UA help the Earth be flat? UA makes FET weaker. Star trails with 2 celestial axi both 90 degrees above the surface of the Earth mean either the Earth is spherical and stationary with the Universe orbiting us or it is spherical and simply rotating. But we can ignore star trails since they are beyond the scope of the OP.
The OP is about the near Sun/Moon. Explain how the near 32 mile wide Sun/Moon match the simplest of observations.
Why do their angular size not change for a near Sun and Moon?
Why doesn’t the near Moon follow the growing and shrinking near Sun’s circles since it needs to for solar eclipses at any time of the year and how would it wobble just right to block the Sun?
If the predictable periodic Super Moon is caused by a wobble bringing it closer to the Earth why doesn’t it moving thousands of miles each day make it shrink?
Why don’t the Sun and Moon visibly slow down as their paths get much shorter for the Northern Hemisphere summer and speed up for Southern Hemisphere summer as their path along the southern Tropic is MUCH longer?
How can the phases of the Moon be seen worldwide just shifted according to latitude with a near Sun/Moon system?
Why do seasonal stars exist at all with a near Sun/Moon system as the Earth wouldn’t be orbiting a distant Sun?
This all assuming that a mystical force/gear could just keep everything as observed. FET has zero explanation that matches reality for just these simple observations for which you and other FE proponents have no answer for.
