gravity. for a long time we have accepted that gravity is a near constant on this planet due to it's mass. i have read articles stating that the force of our gravitational field is a lot less than the actual amount it should be for the size and density of earth. as i have been exposed to a lot of electrical theory at the molecular level(for a lowly tradesman) it got me thinking about gravity and how it relates to energy given off by our spinning mass of molten iron to create our magnetic poles. in short, i wondered if the force of gravity was actually just the force of electrons pulling back to earth instead of our accepted theory of gravitation due to mass. i ended up finding many articles on the subject and it appears our good friend tesla was also thinking the same. tesla always stated that there will be a breakthrough and free energy will be abound to solve our problem of energy needs going forward. we once thought the earth was flat, and that wasn't even that long ago.
