Instead of calculating relative mass and density of an object to quantify gravity and gravitational forces, could Em field density be inserted into these calcs? why the shift from EM to Gr, relative to size? I know string theory is all the rage for unification, but why complicate an already complicated theory with more theory?(adsbygoogle = window.adsbygoogle || []).push({});
