Global Geometric Constraints I: Great-Circle Architecture
The shortest distance across a sphere is not a straight line but a great-circle path.
For planetary reconstruction, great-circle relationships provide a useful framework for testing whether distant observations participate in a larger geometric system.
The Entrance
The Antarctic archive remains the primary geometric anchor of the reconstruction.
If preserved planetary signal exists, great-circle analysis may reveal continuity that is difficult to observe using regional frameworks alone.
The Exit
The Arctic Circle remains the opposing geometric anchor.
The Exit provides an independent comparison domain through which geometric continuity may be tested.
The Middle Mountain
The Middle Mountain remains the organizing bridge connecting Entrance and Exit within the larger geometric sequence.
Observational Constraints
- Great-circle continuity
- Global structural alignment
- Planetary-scale geometry
- Gravity field architecture
- Mantle-scale organization
- Long-duration signal preservation
Geological & Geophysical Constraints
Interpretations must remain compatible with mantle tomography, crustal structure, basin architecture, tectonic evolution, Earth system science, and independent verification.
Research Question
Do great-circle relationships preserve measurable planetary information across geological time?
