Planetary Signal Architecture II: Signal Propagation
Generated signal becomes scientifically useful only if it propagates through the Earth system in measurable form.
The Entrance
The Antarctic archive provides the initiating domain for evaluating signal propagation pathways.
The Exit
The Arctic Circle provides the opposing domain for testing whether propagated signal remains coherent.
The Middle Mountain
The middle mountain remains the central comparison structure within the propagation framework.
Observational Constraints
Propagation may occur through mantle flow, crustal deformation, gravity fields, thermal gradients, magnetic systems, and Earth–Moon coupling.
Reconstruction Question
How does planetary signal move from one domain into another?
