Mantle-Regulated CMB Heat Flux
mechanism
The Earth's magnetic field can't just flip in a sudden violent burst — the slow-moving mantle acts as a thermostat that won't allow it.
Who they are
The way the sluggish mantle controls how fast heat escapes the Earth's core.
What they do
The engine uses this as a hard geophysics fact: the mantle throttles core heat loss, which sets how often the magnetic poles reverse over geologic time.
How it works
Because the mantle can only shed heat slowly, magnetic reversals are 'thermally gated' — spread out over enormous timescales — which rules out any sudden runaway heat event.
Why it matters
It's peer-reviewed evidence the engine uses to knock down doomsday scenarios of an abrupt core catastrophe (part of its ECDO check in Report #103).
The engine's record — word for word
The sluggish mantle limits heat loss from the core, setting the long-term frequency of geomagnetic reversals. Reversals are thermally gated over geologic time — incompatible with sudden exothermic runaway. [TIER GEOPHYSICS-PEER-REVIEW; Apex (a)] [Report #103 (ECDO)]
