Interesting - since all mass is really energy/electrical - that
   makes good sense. Not all planets have magnetism (we do because
   the earth core is moving liquid Iron, making our planet into a
   gigantic magnet) - but planets that have cooled off aren't
   magnetic, so I wouldn't go with the magnetic idea -- BUT since
   all matter has constantly moving electrons (which of course is
   electricity), I can see... what you're saying. Electrical beings
   affected by electrical fields. a tough question is: Where does
   the "Mass" come from that is affected by gravity? Is mass just
   what happens to energy when it "gets cold"? - and what's amazing
   to me about gravity is how easily we 'beat" gravity: Just jump
   up. There, you're stronger than gravity. "
