There is a new original theory put forth by Mark McCutcheon in his book "The Final Theory", which, if correct, is a truly remarkable explanation for gravity, magnetism, electricity and electric fields, the makeup of atoms, etc., etc., etc.  You have to be willing to open your mind to the possibility that his theory may just be correct.  If it is, it will blow your mind.  Since reading the book I have been hoping that someone, e.g. NASA would do some simple experiments that might confirm his theories.  I wish I could explain it to you here, but there is no way I could do it justice.  Get the book and read it.
