Gravity as a Propagation Geometry: From Cone Models to Continuous Bowl Structures

This work explores an alternative interpretation of gravitational phenomena commonly attributed to dark matter. Observations of galaxies and galaxy clusters reveal systematic deviations from the classical inverse-square law: outer rotation curves remain flat, and velocity dispersions in large systems appear too high to be explained by visible mass alone. The standard explanation introduces dark matter as an additional unseen component. In this paper, we propose a different approach. Instead of modifying the force law or introducing new matter, we reinterpret gravity as a flux-density phenomenon governed by the effective area over which gravitational influence is distributed. Within this framework, the inverse-square law is not fundamental, but emerges as a special case of spherical spreading. At larger scales, the effective propagation geometry may change, leading to reduced dilution of gravitational flux without altering the underlying physical principles. We show that a gradual transition in propagation structure—interpreted geometrically as a continuous deformation from isotropic spreading to more collimated flow—naturally explains flat galactic rotation curves and large-scale gravitational behavior without invoking dark matter. This formulation preserves the Newtonian limit at small scales while providing a unified geometric interpretation of large-scale gravitational anomalies.
