A Unified Interpretive Framework for Light, Time, and Causality

This report develops a unified conceptual framework that links the speed of light, the nature of time, and the structure of causality under a single structural principle. Rather than treating these features as independent elements of physical theory, the paper interprets them as expressions of the universe’s maximum rate of geometric evolution. In this view, the constant c is not merely the speed of light but the tempo at which the universe can coherently update its geometric relationships.Light is understood as the physical phenomenon that fully expresses this update rate, making it the pulse of time itself. Time becomes the unfolding of geometric change, and causality emerges as the boundary imposed by the universe’s maximum evolution rate. This perspective reframes familiar concepts—light cones, the constancy of c, and the behaviour of spacetime—not as separate constructs but as different faces of the same underlying structural limit.The framework preserves all empirical predictions of standard physics while offering a clearer conceptual ontology. It explains why light has a universal speed, why causality has a strict boundary, and why spacetime exhibits the structure described by relativity. By grounding these features in a single principle, the report provides a coherent interpretive foundation for understanding the deep unity between light, time, and causality.
