Just want to point out that if this type of discussion is desired but the moderators don't want them here, Avsig on Compuserve does have a place for them and several physicists who love to get involved in such discussions. Issues such as the relativistic roots of gravity, magnetism and even the reason matter appears to be "solid" (all related to relativity) have been the subject of some great threads there. I believe if you go to
