Gravity as Density Shelving III: Everyday Evidence—The Water Cycle, Boiling, and the Out-of-Place Principle

This paper presents the “density shelf” model as a unified alternative framework for gravity, phase change, and the water cycle. Instead of viewing gravity as a force, it is reframed as an emergent organizational effect: matter naturally finds its equilibrium “density shelf” within a structured medium. Applying the concept to boiling water, atmospheric science, and educational practice, the work bridges theoretical physics with hands-on teaching. Includes full lesson plan, side-by-side model comparison, testable predictions, and practical implications for dark matter and energy.<br>
