Antarctic Entrance Response Field
Antarctica remains central to Earth: Day Zero because it may preserve a large-scale entrance response field beneath the ice.
The strongest version of the hypothesis does not rely on a single feature. It relies on the combined behavior of elevation, gravity, subglacial structure, radial organization, and continental preservation.
Observation
Candidate observations include Wilkes Land geometry, East Antarctic interior structure, subglacial basins, gravity anomalies, radial elevation architecture, and possible concentric elevation relationships.
Constraint Analysis
An entrance response interpretation must remain compatible with conventional Antarctic tectonic, cratonic, and glacial explanations while also generating testable predictions.
Signal Question
Does Antarctica preserve recoverable entrance-domain signal from the event?
Verification Path
Testing requires radar, gravity, magnetic, seismic, ice-thickness, subglacial topography, and independent Antarctic reconstruction datasets.
