The Chauhan-Matergy (CM) Closed-Loop Universe Model: A Fluid-Dynamic Framework for Gravity, Dark Energy, and Cyclic Cosmology

This paper introduces the "Chauhan-Matergy (CM) Closed-Loop Universe Model," a novel cosmological framework that presents the universe as a finite, self-sustaining cyclic machine. In this model, space is occupied by a primordial, fundamental fluid termed "Chauhan-Matergy" (CM) characterized by a constant volume-density relationship. Gravity emerges as an inward mechanical density-gradient pull caused by the condensation of CM fluid into localized mass (bypassing the conventional curved space-time manifold and explaining gravitational lensing via optical refraction across density gradients). Accelerated universal expansion (dark energy) is driven by the post-Hawking conversion of matter back into active CM fluid within intergalactic voids. The model preserves quantum information by operating within a strictly finite closed system, resolves thermodynamic entropy degradation through phase-transition resets, and defines a global cosmological reset ("Big Bounce") triggered by the elastic tension boundary limit of expanding space.
