It is absolutely absurd that RE'ers continue to cling onto gravity and and explain away its failings with invisible matter and undetectable energies. It is really just a failure of the RET model as a whole.
Stick to the scales. RET model isn't the model of the entire universe. It's only model of the shape of the Earth and workings in the local scale. And isn't it totally absurd that the FE hasn't even worked out the working model yet? Which can explain how things work locally. Like seasons, day, night, sunset, sunrise and so on.
The seasons, day, night sunset, and sunrise have already been explained long ago. Please read Earth Not a Globe. Also see the Wiki for explanations.
And yes, the RET model is a model of the entire universe. Due to Astronomical Parallax on a spherical body the size of the universe is inferred.
On a Flat Earth the sun can be calculated with Astronomical Parallax to be a few thousand miles from the surface of the earth. On a Round Earth the sun can be calculated to be 95 million miles from the surface of the earth. Very fundamental properties of the heavens were inferred based on astronomical parallax and an assumption of the earth's shape. One assumption of the earth's shape tells us one thing about the size and extent of celestial bodies in the heavens, and another shape of the earth tells us another thing.
Most people are unaware that our perception of the universe is tied to the shape of the earth and the theories of gravitation. Nothing about the universe or celestial bodies have been measured directly in the Round Earth Model. Their properties are inferred based on Astronomical Parallax on a spherical surface and fundamental assumptions of gravity. The size and properties of the universe in Round Earth Model is a direct extension of the earth's shape.
Many people assume that we discovered that distance to the sun and other celestial bodies independently of the earth's shape, but it was not. With Astronomical Parallax the angle of the sun in the sky means one thing on a Round Earth and another thing on a Flat Earth. On each earth the distance to the sun is computed out to different values, which is how we can compute the sun's distance out to a few thousand miles on a Flat Earth. The shape of the earth affects the size and properties of the heavens.
I will look into creating a Wiki page in explaining this more thoroughly.
