There is no accepted theory that explains why the gravitational mass and the inertial mass of a given body are equal. Any new theory that predicted a dynamical origin for the gravitational constant should also predict that the gravitational mass of a body is equal to its inertial mass. Two dynamical theories are outlined. One of these theories does not require the assumptions of dark matter and dark energy to explain cosmological observations.

Keywords: gravitational mass, gravitational constant, dark matter, dark energy
