The Universal Interconnected Nodes Field and Phase-Coherence Propulsion: A Testable Framework for Momentum Exchange with a Universal Substrate

This paper proposes the existence of a universal substrate field, termed the Node Field , underlying spacetime and matter interactions. Unlike known physical fields that respond to energy, charge, or curvature imbalance, the Node Field is hypothesized to resist phase incoherence across the physical universe. We introduce a propulsion mechanism in which coherent electromagnetic oscillations generate a directional phase gradient in producing momentum exchange between a localized system and the universal field without expelling reaction mass. The theory preserves conservation laws by treating the substrate as a momentum sink/source. Quantitative scaling models and experimental falsifiability criteria are provided.
