Reconstruction Geometry III: Planetary Chord Relationships
Geometry becomes increasingly meaningful as scale increases.
Local systems can appear random. Planetary-scale systems often reveal relationships that are difficult to recognize from regional observations alone.
The Entrance
The Antarctic archive remains the primary geometric anchor within the reconstruction sequence.
The Entrance establishes the first fixed point from which larger planetary relationships may be evaluated.
The Exit
The Arctic Circle remains the opposing geometric anchor.
The Exit is evaluated as part of an ordered relationship rather than as an isolated location.
The Middle Mountain
The Middle Mountain remains the organizing bridge connecting the Entrance and Exit.
Within the framework, the Middle Mountain is evaluated not merely as topography but as a central geometric expression.
Observational Constraints
- Polar-to-polar geometry
- Great-circle relationships
- Planetary chord analysis
- Structural continuity
- Global-scale alignment testing
- Geophysical correlation
Geological & Geophysical Constraints
Any proposed chord relationship must remain compatible with crustal structure, mantle tomography, gravity fields, plate tectonics, and Earth system science.
Research Question
Do planetary-scale chord relationships preserve information that is difficult to observe at regional scales?
