Gravity doesn't exist, just weight, mass, density. Clouds are at the height they are because of its weight. Another thing that don't exist is space, well outer space. We are trapped in a dome on a flat earth. The stars are just a reflection off the dome, your looking at a mirror. A time lapse of the stars will prove a flat earth. If earth were a round ball, the stars would go from left to right across the sky. Don't forget the supposed wobble, so how does the time lapse show the stars make complete perfect circles. Energy is just magnetism. North, south, and neutral poles. Electron, proton, neutron, same thing. E=mc2, energy equals magnetic current squared (+-). Your experiments would work better if realize magnetism is everything. There's no core, it's a black hole sun!
