As a step towards a better (non-“mass”-based, non-Newtonian) formulation of “gravity”, let’s consider the math of basic soap-bubbles and balloons.

Fundamentally, atoms/molecules in a medium/material are drawn to each other or bound by some form of binding force (dipole-binding, electron-binding, covalent binding etc.). This is essentially the force holding all substances together and this force is small to none and even negative (repelling) in a gas whereas it in a fluid is conclusively …
