RE:More gravity...

Eprom,

You'd be surprised how close to the true idea of General Relativity you have gone. Indeed, in GR gravity is the curbature of spacetime due to the energy density in some region. The more the energy density in some place, more the spacetime is curved around it. But I'm afraid that your claim that a sudden disappearance of a mass body would cause an anti-gravitational pull is wrong. What would happen is that spacetime would become again flat (no gravity at all) but this change would propagate at the speed of light.
