Compression Phase Gravity

Gravity is traditionally described either as a force between masses (Newton) or as the curvature of spacetime (Einstein). These frameworks successfully capture the geometry of gravitational fields, yet neither explains why different bodies produce different gravitational strengths. Both treat planets and moons as idealized masses, overlooking the fact that real worlds differ substantially in stiffness, compressibility, layering, and internal phase structure. Compression Phase Gravity (CPG) introduces a complementary physical mechanism: gravity arises from the compression of space around a body, and the surface gravity observed at its boundary reflects the inverse pressure of this compressed region. The efficiency with which a body transmits this compression depends on its internal composition and structure. CPG formalizes this through two universal relations. Canonical Equation 1 provides the geometric compression prediction of surface gravity under perfect transmission. Dunia’s Impedance Law quantifies how real bodies deviate from this geometric ideal, yielding a dimensionless impedance value that reflects each world’s internal response to compression. Across gas giants, icy moons, rocky planets, and smaller bodies, the impedance values form a smooth and physically interpretable spectrum: gas giants occupy the low-impedance regime, icy bodies cluster tightly around unity, and rocky planets lie near unity with small deviations linked to stiffness and differentiation. When combined, Canonical Equation 1 and Dunia’s Impedance Law reproduce observed surface gravities to within numerical precision for all bodies tested. CPG therefore offers a unified geometric–impedance framework for gravitational strength, grounded in compression mechanics rather than attraction or curvature. It provides both a predictive model and a diagnostic tool for inferring internal structure from gravity alone, suggesting that gravitational behaviour is shaped jointly by geometry and material response — a structure long present but previously overlooked
