How Gravity Differs from the Electrostatic Force

The electrostatic force and gravity have a number of differences that seem to indicate that these forces must be largely unrelated. However, on closer inspection we find that these differences are fully accounted for in a model where gravity is due to an imbalance in the electrostatic force.

Surface phenomenon vs universal phenomenon

The electrostatic force is always calculated from the surface of objects. This is because this phenomenon is due to an excess or deficiency in electric charge. Electrons stick to certain materials, and they can be rubbed off from other materials.

This happens exclusively on the surface of these materials. Hence, the need to calculate this force from the surface of materials rather than their center.

Gravity on the other hand, if due to an imbalance in the electrostatic force, must be calculated from the center of bodies. This is because an imbalance of this sort is additive. Every atom has this imbalance, so every atom has to be accounted for.

Newton's shell theorem proves that this must be so.

Dependent vs independent of material types

The electrostatic force acts differently on different types of materials. The chemical and physical properties of materials take part in determining the strength of this force.

This is due to the need for charge imbalances in order for this force to work. Materials that resist charge imbalances are therefore less affected by this force than other materials.

However, an imbalance in the electrostatic force will exist regardless of material types. If gravity is due to such an imbalance, all materials will attract each other.

It doesn't matter if a material resists charge imbalances, because the addition or subtraction of electrons has nothing to do with the inherent imbalance that exists in all materials. All that matters is the total number of electrons and protons involved.

Shielding vs no shielding

The electrostatic force induces charge imbalances on the surface of materials. This serves in turn as shields of various qualities. However, there's no way to shield a universal imbalance, because such imbalances are additive. It doesn't depend on the type of materials used.

Any gravity "consumed" by a concrete floor will be matched by gravity "produced" by the same floor. So, the floor doesn't take away any gravity from us as we sit upstairs, and this goes for any floor regardless of material used.

Conclusion

Gravity, if due to an imbalance in the electrostatic force, will result in a universally attracting force that acts from the center of objects, independent of material types. So, there's no reason to dismiss this idea simply because the electrostatic force acts differently.
