Gravity is Just Density
The natural physics of density and buoyancy determine that objects denser than the medium surrounding them sink while objects less dense than the medium surrounding them rise. This is the reason raindrops fall down through the air, while air bubbles rise up through water. Objects at perfect equilibrium with the medium surrounding them levitate in place like the balloon in the following video.
