The Mediated Interaction Aether Model: Instantaneous Field Updates with Emergent Finite Signal Propagation

This paper introduces the Mediated Interaction Aether Model (MIAM), a conceptual framework proposing that all physical fields are globally updated instantaneously, while local responses remain finite and causal. The model provides a unified ontology underlying classical, relativistic, and quantum phenomena, offering a coherent explanation for nonlocal correlations and emergent Lorentz invariance. MIAM is formulated to be empirically testable through subtle, measurable effects on signal timing, interferometric phase shifts, and entanglement order.
