The Single Medium Hypothesis

A theoretical framework proposing that electromagnetic waves, gravitational waves, and matter are different modes of deformation in a single physical medium. The gravitational constant G is derived from medium properties within 0.03% of the measured value. The electromagnetic-to-gravitational hierarchy ratio is reproduced within 0.2%. A unified Lagrangian and 21 benchmark tests across quantum, electromagnetic, planetary, and cosmic scales are presented, along with testable predictions.
