Rotating Earth IV: Long-Duration Relaxation
Planetary response occurs on multiple timescales.
Observation
Seconds, years, millions of years, and billions of years all participate in the relaxation of a Moon-formation-class system.
Constraint Analysis
Many observable structures may represent relaxation products rather than primary event features.
Core Question
How much of modern Earth reflects original forcing versus billions of years of relaxation?
Transition
The next sequence begins building the quantitative framework through Rotating Earth V–VIII, introducing rotational scaling, response domains, energy pathways, and constraint mathematics.
