The gray shadow fringe area of the Earth's shielding provides a gradual transition from the no-shielding area to the full shielding of the black shadow area. As a sea passes through the black shadow shielding area it is nearly completely shielded from the gravitational effects of the Sun or Moon on the opposing side. The following physical characteristics are readily predicted by this radiant pressure model for gravity. Some have been shown to exist with this paper. Others should be seen with a minimum of investigative efforts.
Unbalanced force acting through a distance does exist in radiant space.
All remote forces result from an unbalanced radiant flow. All remote forces follow the inverse distance squared law of shadowing geometry. Shadowing geometry occurs only within a radiant field. Gravity or radiant pressure unbalance does increase in proportion to the amount of shielding with increasing planet diameter and density. Planet diameters do become large enough to stop all opposing flow through the planet.
