Gravity as the Second-Order Relativistic-Manifestation of   Electrostatic-Force
  It is well known that magnetic force between two current carrying conductors is a relativistic manifestation of net electrostatic force between relatively moving electrons & protons of the two wires. On similar grounds but with more accurate considerations i.e., of second order relativistic considerations, it is shown here that gravitational-force between two bodies is in-fact due to relativistic manifestation of net electrostatic force between protons & revolving electrons in atoms of the two bodies. As special-relativity provides a bridge between electricity and magnetism, in somewhat similar way (as described in the paper) it is shown that once again it is the special-relativity which provides the much sought-after link between electrostatic force and gravitational force. If magnetism is the first-order (velocity-dependant) effect of moving electrons in conductor, gravitation is the second-order (acceleration-dependant) effect of revolving electrons in atoms. The new proposed gravitation-theory seems to be well in accordance with gravity behavior i.e., it correctly predicts that gravity is a long-range attractive-force proportional to masses & follows inverse-square-law and is transmitted with the velocity of light.
