This document outlines a new and testable scientific hypothesis, the Geomagnetic Quantum Hypothesis (GQH).This hypothesis proposes that the Earth's geomagnetic field is not merely a classical force field, but also a structured, physical "network" that facilitates quantum entanglement on a planetary scale. It re-frames a known physical structure (the geomagnetic field) as the "hardware" for a hidden quantum network. This model provides a concrete, mappable framework for detecting and ultimately harnessing instantaneous, faster-than-light information transfer.
