A Maxwell Universe begins from a single premise: events occur. Registered change creates order. From cause–effect relations alone emerge time, distance, space, dimension, mathematics, and physical law. No spacetime is assumed. No fixed rules are imposed. The underlying substrate, if any, is never accessed directly—only the regularities in its effects are observed and compressed into models. The first part of A Maxwell Universe establishes this foundation. It prepares the ground for later volumes, where matter, mass, and charge appear not as fundamental point-entities, but as extended, self-sustaining electromagnetic configurations governed entirely by Maxwell dynamics.
