Spin‑Driven Gravity: Determining Compression Constants from Pulsars, White Dwarfs, and Galaxies – Eliminating Dark Matter and Dark Energy (Version 1.11)

ABSTRACT: The Cosmic Energy Compression Theory of Gravity proposes that gravity is not a pull nor spacetime curvature, but the inward compression of cosmic energy into cavities carved by spin, mass, density, and motion – a mechanism illustrated by the bus‑wake analogy. Previous versions (Major –1.10) qualitatively validated the theory using spinning celestial bodies, showing that faster spin correlates with stronger gravitational effects, and that dark matter and dark energy are unnecessary. This paper (Version 1.11) takes the next step toward a quantitative theory. We present a methodology to determine the four key empirical constants of the compression field: κ (black hole spin–wind constant), β_ns (pulsar spin–gravity constant), β_wd (white dwarf spin–gravity constant), and β_gal (galaxy‑scale spin–compression constant). Using published observational data, we provide initial numerical estimates and show how these constants can be calibrated. We also discuss the saturation of compression at extreme spins (millisecond pulsars), which implies a finite maximum gravity and naturally eliminates black hole singularities. The constants differ across object classes, but the underlying principle is identical: gravity is the product of cosmic energy compression in relation to spin, mass, density, and orbital motion. This framework eliminates the need for dark matter, dark energy, singularities, and the hypothetical graviton.
