Cycle Controls
Precession (Great Year)
25,772 yrs
Axial wobble shifts equinoxes vs stars.
Obliquity
41,000 yrs
Tilt changes polar summer strength.
Eccentricity
100,000 yrs
Orbit shape amplifies/dampens precession.
Position in the ~26k cycle (0–100%)
27.5%
≈ 7,089 years into the cycle
“Instability score” (toy model)
0.42
Higher when multiple cycles “peak” together.
Note: the “instability score” here is just a visual intuition tool, not a scientific prediction. It’s meant to illustrate Carlson’s idea that timing can be shaped by cycle overlap.
