Thus E comes from charge density and B seems to have no source. So one might ask "where does B come from?".The answer "from Relative motion!".<br /><br />The Newtonian Gravitational field is also described by a Divergence: <br /><br />Del.g = -4(pi)G(rho) (from Wikipedia!)<br /><br />Here the source is the matter density rho.<br />The corresponding Curl equation would be:<br /><br />Del X g = 0<br /><br />Though if Gravitational Torsion existed this might not be correct.<br /><br />I see that there is an ambiguity over the definition of AGI in Wikipedia. Perhaps I should write about that another time.<br />Royhttps://www.blogger.com/profile/17844610890344836500noreply@blogger.com
