As you may or may not know, at least the magneto guy from Theoria Apophasis knows that a water and a glass is a condensor. That means that it can be electricaly charged. The guy does not think we live inside earth. I think he did not thought about that. His ideas makes sense why we do have electrifical discharges between the glass sealing with water above making it works as a condensor and the earth full of iron inside.
His idea is that every electric phenomen is a distortion, and he think that everything is an electric phenomen. If the glass sealing is distorted it create electricity as it is a capacitor that is able to do that. As you know the electricity creates a magnetic field from the flow of the electric current. And that force is directed towards the earth. Below the earth should be another electric current and the point where both magnetic force "colide" creating the point of inertia. The "center of gravity" should be way below the sea level where both magnetic fields find their inertia point where the magnetic force is strongest. If this theory is true, below a certain level below the sea the pressure should be lower if it happens to be past the "center of gravity". That would have prove it once and for all that the gravity is an electrical phenomen.
And that would make sense as gravity is the only force that is a pull force in the physics world, everything else is a push force. If it would be proven experimentaly that would make every force in the universe a push force.
I need to really learn more about this guy idea about the gravity, but I think this guy is the closest to the truth about gravity as you can get. Maybe I understood something wrong about his ideas so sorry about that but that is my knowledge about it for today. Ill learn more.
What is the poles magnetic force you ask? It could be the result of the either a) rotating sky, and its like the similiar mechanism like in moving earth b) octahedron that is supposed to be in my "theory" is having the highest magnetism at its peaks and those are directed towards the poles.
a lot of what you just said would be impossible in a hollow earth (where we live on the inside of the earths crust. so i am confused as to your stance on the matter.
