Areal Scale Constraints
A candidate entrance domain associated with a Moon-forming-class event must satisfy dimensional requirements consistent with the scale of the proposed forcing mechanism.
The central question is not whether a structure exists, but whether its dimensions are physically compatible with the class of event being evaluated.
Scale As A Constraint
The Earth: Day Zero framework treats areal extent as a first-order constraint.
A candidate domain that is too small may fail to accommodate the required energy scales. A candidate domain that is excessively large may become inconsistent with reconstruction geometry, planetary response, or Earth–Moon system constraints.
Orders Of Magnitude
Moon-forming-class events operate at planetary scales rather than local geological scales.
Consequently, candidate entrance domains should be evaluated using hundreds-to-thousands of kilometer dimensions rather than localized crater analogs.
Constraint Windows
The objective is not to identify a single preferred diameter.
The objective is to determine a plausible dimensional window that remains compatible with:
- impact energetics;
- planetary deformation;
- geometric reconstruction;
- Earth–Moon system formation.
Implications For Antarctica
The Antarctic candidate domain is therefore evaluated primarily as a regional-scale structure rather than a discrete crater analog.
Future papers refine dimensional requirements and explore whether candidate entrance-domain geometries remain compatible with larger framework constraints.
