The gravitational potential energy of the actual Earth has now been estimated at −2·485 × 1032 J. Three density models of the hypothetical Earth before the hypothetical expansion have been adopted for estimating the internal energy necessary for expanding: 7 × 1031 J. No dynamical evidence exists for the origin of this energy in the last 450 × 106 y. The hypothetical increase in the Earth's mass M of about 0·4 M since 2 × 108 y B.P. required for a dynamical balance has also no support in the paleodynamics of the Earth-Moon-Sun system since the M. Ordovician.
