Lower-Mantle Mass Imbalances / Precession
mechanism
Some claim Earth's crust could suddenly flip — but the real geological process behind it takes millions of years, not moments.
Who they are
This refers to slow mass imbalances deep inside Earth, at the boundary of the lower mantle.
What they do
These imbalances gradually shift Earth's slow wobble (precession) over enormous timescales.
How it works
Things like gases seeping out of Earth's core create slow volume-and-mass shifts at the lower-mantle boundary that drive precessional change over millions of years — but some proponents wrongly read this as a mechanism for a sudden flip of Earth's spin axis.
Why it matters
It matters because it corrects a misreading: the process is real but slow, so it cannot cause the sudden pole-shift catastrophe some claim.
The engine's record — word for word
Slow volumetric mass imbalances (e.g. exsolved core gases) at the lower-mantle boundary drive precessional change over millions of years; proponents misread this as a mechanism for sudden spin-axis realignment. Slow, not sudden. [TIER GEOPHYSICS-PEER-REVIEW] [Report #103 (ECDO)]
