I remain unconvinced of the flat earth "buoyancy" theory of gravity because of the inconsistencies and contradictions, and because of the inability of proponents to explain it. I wonder if this one would be more suitable: Le Sage's theory of gravitation
From where ever you are on earth up is up: plants grow up in the material world.. its where we are on this earth...or this density... things above this density are of less density and things below us are of more density in relation to AetherBut if you are up in America, Chinese and Aussies are down. Of course, they don't know it.
Or a cube.
