Universal Pixel Mechanics: A Discrete Spatial Framework for Fundamental Physics

This work introduces Universal Pixel Mechanics (UPM), a discrete spatial framework in which space is treated as quantized structure rather than a continuous background. The model explores how gradients of structural condensation give rise to inertia, acceleration, pressure, and large-scale structure without invoking continuous fields. The framework is applied to motion, equilibrium, thermodynamic behavior, and cosmological structure, proposing a unified mechanism underlying mass, gravity-like behavior, and relaxation dynamics. This document represents Version 2.0 of the theory and is intended as an open, exploratory research contribution.
