Midpoint Domain Reintroduction

With candidate entrance and exit domains established, attention now turns to the third primary geometric object within the Earth: Day Zero framework: the midpoint domain.

The midpoint domain represents the most restrictive component of the reconstruction because it must remain compatible with both primary domains simultaneously.

The Three-Domain Requirement

A candidate midpoint must satisfy geometric relationships with both the Antarctic entrance domain and the Arctic exit domain.

Failure to satisfy either relationship weakens the broader reconstruction.

Constraint Amplification

The addition of a midpoint domain significantly reduces permissible solution space.

As the number of independent geometric constraints increases, coincidence becomes a less efficient explanation.
