Scientific paper

Large changes of the Earth's radius, both expansions and contractions, have been postulated by various authors. Physical explanations involve either some form of Ramsey's hypothesis that the core is a high-density form of mantle material, or a variation of gravitational constant with time, or both. In the light of experiments reaching core pressures, Ramsey's hypothesis is not tenable. For the ``real Earth'' having chemically distinct mantle and core, the increase of radius for a decrease of the gravitational constant from 2G to its present value G is about 370 km; this is a greater change of G than is allowed by other considerations. It appears that so long as the Earth has had its present mass, changes of external radius are limited to amounts of the order of 100 km.
