It is good to keep an open mind. Gravity is the weakest of the forces, so
weak is what we should be looking for. But "magnetism" should have a
preference for a conductor over an insulator, and gravity has no such
preference. Keep in mind that magnetism is just electric charge and motion
"disguised".
