Spatial Constraint Hierarchies

Not all constraints carry equal evidentiary weight. Earth: Day Zero therefore organizes spatial observations into hierarchical levels based upon scale, independence, and resistance to coincidence.

This hierarchy provides a systematic method for weighting evidence rather than treating all observations as equivalent.

Hierarchy Level One

The highest-order constraints are planetary-scale geometric relationships.

These include domain placement, great-circle relationships, midpoint structures, global-scale alignments, and large-scale ordering patterns that remain observable despite billions of years of geological modification.

Hierarchy Level Two

The second level consists of regional structural relationships.

These include basin architecture, tectonic boundaries, crustal organization, regional gravity signatures, and large-scale geological context.

Hierarchy Level Three

The third level includes local geological features.

Local observations may be highly informative but are generally more vulnerable to erosion, tectonic overprinting, and preservation bias.

Constraint Weighting

A framework that relies exclusively on low-level observations risks becoming unstable.

Conversely, a framework supported by multiple independent high-level constraints gains explanatory robustness because large-scale relationships are more difficult to generate accidentally.

Application To Earth: Day Zero

The entrance domain, exit domain, midpoint domain, and great-circle framework are evaluated primarily as first-order constraints.

Subsequent geological, geophysical, and Earth–Moon system observations serve as secondary and tertiary tests of those primary relationships.

This hierarchy provides the structural logic underlying the remainder of the Earth: Day Zero reconstruction.
