Reconstructing Physics from First Principles: The Axiomatic Universe Model

This paper introduces a geometric framework that reconstructs fundamental physical laws from a minimal set of assumptions: action, invariant velocity (C), and geometric confinement. Without presupposing mass, force, or spacetime structure, the model explores how rest mass, gravitational and electromagnetic forces, and fundamental constants like the fine-structure constant naturally emerge from geometric and energetic constraints. Physical concepts traditionally viewed as fundamental, such as inertia and potential, are derived explicitly from the geometry of causal loops. The resulting structure closely mirrors known physical laws and constants, providing a unified conceptual foundation for further exploration of fundamental physics.
