Well, gravity is somewhat distinct from FE per se. I'm not sure why the two get conflated all the time.
Whether or not one is capable of getting the math for "gravity" right, the explanation of how masses can act upon one another at a distance has remained elusive. Some have tried to attribute it to electromagnetic fields, Einstein to simply a curve in space time, and the most recent theory being that is has to do with thermodynamics.
What FEs don't do a great job of is where they say that all you need is buoyancy. In a sense that's true, and I submit that buoyancy/density suffice to explain the movement in and of itself, no different than how things move up or down in water do to their relative density. But what's missing is an explanation for what might cause the DIRECTIONALITY of the movement, up or down. Why do more dense things move "down"?
Gravity isn't the only possible explanation for the directionality of the movement. We know that the earth has a negative charge, so there could be electromagnetism involved. It could be due to the flow of ether. It could be due to atomic forces of some kind. I saw a video of an MIT professor who said that the force of gravity is so weak on the earth that it's a non-factor and that everything on earth is explained by electromagnetism, and that gravity only has any effect between things at the scale of planets.
I guess where gravity enters into the GE/FE debate is that the explanation for how things can stick to the "bottom" of a ball earth is "gravity". But the debate about whether such a force, whether it's gravity or electromagnetism or whatever, exists I find to be irrelevant vis-a-vis the shape of the earth, because the same force that allegedly would cause things to stick to the bottom of a ball would also cause the downward motion of things on a hypothetical flat earth. So if there's no gravity, but it's really a type of electromagnetism, then that electromagnetism could be the explanation for how things stick on the bottom of a ball. So I'm not really sure which argument it's really addressing.
I find the gravity debate to be something of a red herring. FEs sometime think that if gravity doesn't exist, then it makes a globe earth impossible, but it really doesn't depending on whatever else you end up replacing gravity with.
With all the physicists and universities in the world trying to prove their Newton/Einstein theories of heliocentric gravity so that the Church of 1616 and 1633 can be ridiculed, few would know the truth of universal movements. There are probably two explanations, one of nature and one spiritual. These are confined to readers of CIF as you will not find them in any physics book or any book coming out of the Vatican since 1835. Well, here is the greatest secret the history of faith and science. Domenico Cassini (1625-1712), God's astronomer, a geocentrist, falsified Kepler's and Newton's elliptical orbits. He measured orbits as Cassinian Ovals. It was many years later when some laws of electromagnetism were discovered that it was found Cassinian ovals are related to positive pole electromagnetic forces.This link can be demonstrated by spreading iron-filings over a 2 positive-pole magnetised surface. This will form directional charge patterns that constitute a whole series of Cassinian ovals.

Now here are the orbits of all sun and planets we see from Earth. But we also see a sight called stellar aberration and stellar parallax. For this to be the orbit of the sun and stars must be linked, meaning the stars must also move in Cassinian ovals.
And now we come to the spiritual side. To keep all the stars, planets, moons and sun from collapsing into one another, God put an angel in charge of each.
‘It is true that all the stars and heavenly bodies by the natural direction given them by God pursue their several courses but these great worlds are material and, therefore, as the Angelic Doctor points out, are liable to decay and deterioration. To prevent therefore, disorder and confusion in the multitude of heavenly bodies which are whirling through space with inexpressible speed, God gives each one, in His all-wise Providence, an Angel to keep it in its course and avert the dire calamities that would result were it to stray from its allotted orbit…. Few people think on all this when on beautiful star-lit nights they gaze on the sky and the myriads of stars. How fitting it would be to salute the countless Angels who guard these stars: “Oh glorious Angels of the stars we love you. Please bless us and shower on us your protection.”’---E.D.M.: All about Angels, Catholic Printing Press, Portugal, 1945, pp.31, 32.
Having first created heaven and Earth in darkness, the Book of Genesis tells us God then created ‘light.’ He then divided this light from the original darkness in creation. Today, as understood by mankind, science knows what that light is, describing it as within a certain portion of the electromagnetic spectrum. Accordingly, when God created light, he in effect created electromagnetism. God then created the sun and stars to generate such light in ‘heaven and Earth.’
But there is another secret being kept from humanity. I will keep that for another post.
