Did you miss this part about A+B=C but A and B can also exist has an entity?And yet neutron stars, which are composed of compacted degenerate neutrons (no "atom polarities" as you describe above) have quite strong gravitational potentials. In addition, by adding nothing but neutrons to atoms (i.e. increasing their atomic weight but not changing their place on the periodic chart) their gravitational force increases. More gravity but no polarity increase. So your theory fails yet again.
An object freely falling in a gravity well is being affected by gravity but is not "undergoing contraction." Indeed, tidal forces will tend to pull it apart if the gradient is high enough. So another fail.
As a general comment, the validity of a scientific argument is not how cool you think it sounds, or how much you like it. It is whether or not the real world operates the way you claim it does. If the real world does not match your argument, it is your argument that is flawed, not reality.
Incorrect any object wants to contract, the force is centripetal isotropic to the center of mass, gravity wants to contract the surface but the density under it stops this, when you leave the surface you are expanding away from gravity, up and down are arbitrary, down is contracted towards gravity, Up is expanding away from gravity, the Universe does not have a this way up sign, you are saying the Universe is not expanding, the opposite of expand would be contract, and also again you avoid the questions conferring what i say to be true that you do not have the ability to answer my questions I ask you.
