You don't even know that your own model has since Einstein entirely disregarde Newtonian gravity.
The same will happen in due time with the relativistic nonsense as it's more make-belief material, and not consistent with observations.

Nice claims, but you're not addressing the point here. You can see with your own eyes, in the Cavendish experiment, attraction between masses that has nothing to do with density.
Electrostatics is a real, verifiable thing. Get a vandergraaff and start making things "anti-gravity"!
Electrogravitics is very interesting and real, yes. But it proves nothing in relation to your "density" theory.
Gravity does not depend on density, and I proved it to you. Why do you keep ignoring evidence that contradicts your theories?
