Midpoint Response Field
The midpoint response field tests whether the event reconstruction contains internal geometric structure beyond a simple entrance-exit relationship.
Within Earth: Day Zero, Hawaiʻi and Mauna Kea remain candidate midpoint-domain observations requiring strict evaluation.
Observation
Candidate observations include Mauna Kea scale, Hawaiian volcanic persistence, Pacific basin position, midpoint geometry, and relation to the Antarctica–Mariana reconstruction.
Constraint Analysis
The midpoint hypothesis must remain stable under uncertainty, plate reconstruction, alternative midpoint candidates, and competing geological interpretations.
Signal Question
Does the Hawaiian domain preserve midpoint response information, or is its apparent significance a coincidence of later Pacific hotspot evolution?
Verification Path
Testing requires great-circle analysis, plate-motion correction, volcanic chain reconstruction, bathymetry, mantle plume data, and independent geospatial verification.
