Nothing in nature pulls. Even where you are apparently pulling, as with a rope, a chain or a vacuum flow, you are employing the act of pushing entirely. A vacuum suction uses superior pressure to push. A rope or chain employs friction to maintain a directional force, all pushing, no pulling.There is no pulling in nature, only pushing.This is why we cannot derive a unified field theory to explain forces that apparently pull.
