Is it possible to create an anti gravity device?
Two bodies both having mass (the sum of the mass of all the protons, neutrons and electrons) attract each other in accordance with the inverse square law. The moon and the earth attract each other. The earth attracts you giving you weight on a measuring scale. However, you also attract the earth because you have mass. It is kind of like the kid pulling up a weed even though the entire world was holding onto it. It would seem that to invent (or discover?) an anti-gravity device, it would be necessary to invent (or discover?) anti-mass. The fact that none has been observed in Nature is no proof that none exists. In order to prove that red seagulls exist in Nature you must discover only one (hopefully not a fake?). If a weight on earth was composed of protons, neutrons and electrons having negative mass, it likely would have fled into space long ago. Scientists have discovered anti-matter were for example a positron will annihilate and electron and release energy but both are known to pos
