A Modified Theory Of Newtonian Mechanics
  A specific form of the inertial law is presented by which we can have some deeper insight into the essence of mass and inertia. In this modified theory, there is no need to keep the concept of absolute space and Newton's third law as principles. By introducing a convenient form for gravitational law the coupling constant G becomes a function of inertial parameters of the universe.
