Signal Analysis II: Competing Explanations
Multiple explanations may account for the same observation. Scientific reconstruction requires systematic comparison among competing models.
The Entrance
The Antarctic archive serves as a primary testing ground for competing geological interpretations.
The Exit
The Arctic Circle provides a secondary domain for evaluating explanatory consistency.
The Middle Mountain
The middle mountain provides a central comparison domain connecting the larger reconstruction.
Observational Constraints
Competing explanations must be evaluated using geology, geophysics, stratigraphy, planetary energetics, and Earth system science.
Reconstruction Question
Which explanations best satisfy the largest number of independent observations?
