The Definition of Gravitational Permittivity and Field Density in Closed Surface Theory

This paper defines the relationship between gravitational permittivity (), gravitational acceleration (g), and the field intensity () through the expression .By analogy with electromagnetism, where D=εE, this relation describes how gravity depends on the medium’s structural capacity to transmit or buffer gravitational stress.Within Closed Surface Theory, represents the responsiveness of space curvature to mass confinement — a measure of how the medium converts temporal curvature into spatial force.A solid medium with low conducts gravity efficiently, while gases or vacuum with high act as gravitational insulators.This framework introduces the concept of gravitational semiconductivity, linking mechanical, electromagnetic, and geometric interpretations of gravity into a single unified formalism.The study concludes that the gravitational field is not a universal constant but a medium-dependent closed-surface response, with serving as the key structural constant connecting curvature, acceleration, and energy propagation.
