Maxwell's Explicit Medium and the Logical Default of Substrate Ontology: Requirement for Non-Substrate Theories to Demonstrate Consistency with All Physical Phenomena

This paper examines the ontological interpretation of Maxwell’s equations in the contextof a conditionable space substrate. Maxwell’s equations are universally accepted as thecorrect mathematical description of electromagnetic field behavior, yet they do notspecify the physical carrier of electromagnetic energy, momentum, and propagation. Thiswork demonstrates that Maxwell’s equations are fully consistent with a model in whichspace itself possesses physical properties including energy storage capacity, conditioningresponse, and transport behavior. Historical analysis shows that Maxwell originallyconceived of electromagnetic energy as residing within a medium. Modern vacuumconstants, including permittivity and permeability, define intrinsic response properties ofspace itself. The electromagnetic energy density equation demonstrates explicitly thatenergy resides within space independent of matter. Propagation velocity determined byvacuum constants corresponds formally to wave propagation in structured media. Thispaper establishes that electromagnetic field theory represents the mathematicaldescription of substrate conditioning rather than excluding the existence of such asubstrate. The field description and substrate interpretation are therefore complementary,not contradictory. This reconciliation provides a coherent framework for interpretingelectromagnetic phenomena in a physically intuitive manner while preserving allpredictive success of Maxwellian theory.
