Mass and gravity are linked. There is no doubt about that. Massive objects that are hard to accelerate are also heavy. The more massive an object is the more strongly it is pulled down by gravity. The relationship is clear and direct.
However, this does not say anything about the fundamental nature of gravity or mass. We know very little about either. Both gravity and mass are puzzles. We don't know what they are or what is causing them.
An interesting feature of mass is that it is tied up to energy. The mass of an object can be increased by adding energy to it. Mass, energy and gravity are in other words linked.
This becomes particularly interesting in light of the recently discovered 5.9 year cycle in which our planet varies in both its gravity and the length of its day. Earth slows down periodically, and synchronously with a change in its gravity.
A simple explanation for this would be that the mass of our planet increases periodically. This would slow the rotation of Earth due to preservation of angular momentum. In a gravity model where mass attracts mass, it would also increase gravity.
The energy input for this would presumably be electrical. If so, the 5.9 year cycle is telling us that gravity, mass and energy are all electrical. An increase in electrical charge would increase all of these parameters.
This would further imply that the distinction between the two main gravity models, in which one states that gravity is mass attracting mass and the other states that gravity is charge attracting mass, is somewhat artificial.
In a paradigm where mass is an electrical phenomenon, the amount of charge and/or current there is in a body is what defines its mass. The capacitor model is not a replacement of the Newtonian model of gravity. It incorporates it. By emphasizing charge rather than mass, the capacitor model shifts the focus away from a static view of mass to a fluid view. It also shifts focus away from a monopole view of gravity in favour of a dipole view.
Newton's mistake was to assume gravity and mass to be static and monopole. Apart from that he was right. Mass is directly related to gravity. However, both are again directly related to electricity, and that's where the potential for a better understanding of both gravity and mass lies.
