| contents | <p>This paper proposes that a significant component of the gravitational phenomena attributed to dark matter may instead arise from low-amplitude, long-coherence metric perturbations generated by distributed entropy production in the cosmic medium. In this framework, local entropy injections - originating from stellar processes, black-hole accretion, supernova feedback, and large-scale structure formation - produce spacetime "micro-ripples" whose cumulative gravitational influence behaves like a pressureless cold dark matter fluid.</p> <p>We develop a conceptual and mathematical description of these entropy-induced perturbations, show how they propagate as long-range scalar distortions of the metric and demonstrate how their spectral characteristics can reproduce key features normally associated with cold dark matter: flat rotation curves, gravitational lensing signatures and hierarchical clustering. We outline observational tests involving weak-lensing statistics, halo profiles and cross-correlation with star-formation and black-hole accretion histories.</p> <p>This entropy-driven micro-ripple model offers a falsifiable, thermodynamically grounded alternative to particulate dark matter, preserving the successes of ΛCDM while proposing new avenues for detection and discrimination.</p> |
