is similar to the Newtonian gravitation law:
This suggests similarities between the electric field E and the gravitational field g, so sometimes mass is called "gravitational charge".
Similarities between electrostatic and gravitational forces: - Both act in a vacuum.
- Both are central and conservative.
- Both obey an inverse-square law (both are inversely proportional to square of r).
- Both propagate with finite speed c.
Differences between electrostatic and gravitational forces: - Electrostatic forces are much greater than gravitational forces (by about 1036 times).
- Gravitational forces are attractive for like charges, whereas electrostatic forces are repulsive for like charges.
- There are no negative gravitational charges (no negative mass) while there are both positive and negative electric charges. This difference combined with previous implies that gravitational forces are always attractive, while electrostatic forces may be either attractive or repulsive.
- Electric charge is invariant while relativistic mass isn't

Pat,
I have been trying to not get myself involved in your gravity discourse too much because I want to follow the discussion between you and others. However, since I am partly to blame for the lag, and I do have some 'different' views than I believe others have, here is my view on gravity.
Gravity is a force that I consider an internal force. It does not exist by itself, but is the byproduct of the other forces. Without the other forces, gravity does not exist, according to me, and should therefore be fully explainable by the other forces. However, it is important to note here that it is a collective force, so the quest to relate it to just one other force seems improbable to me. The other forces exist within a specific framework of play, and it can get rather complex.
Before I'll explain the simple set-up of the complex situation, I want you to know that I prefer to write in ordinary language, so all can understand. Apologies if the discussion muddies therefore to some extent. In a previous post on the pyramid of four forces, E, M, S, and W (but not G), I portrayed them as the four colors: red, blue, yellow & green as 'corners' of the pyramid.

(this link shows a beautiful visualization of it created by Austin). Where these colors get together and form gray, that's where gravity plays its role. As it happens to be, the gray area is an internal cone in the pentaist pyramid. And as a concept, the cone happens to be the single concept that describes all the gravitational aspects in our universe. I see that as a confirmation that the pyramid is a correct concept.
Thank you for creating this excellent thread. I hope I can contribute in keeping it interesting.
Best to you, too.
P.S. One more post with two excellent visuals, also by our creative artist Austin, on the pyramid viewed from the bottom and viewed from the top:
