Hi Graham,
The singular vortex mechanism refers to the smaller grey spheroid in precession that wobbles in a two-axis spin in a geometrical gravity field. The main axis of the singular vortex mechanism is on the rotation axis exerting a consistence centrifugal force on the viscous mass, the secondary axis is on the revovling axis that provides a consistence driving force.
The precession effect of these forces affecting the whole mass of the wobbling spheroid are amplified enormously from the core towards the surface on lower density viscous mass layers that initiates the fromation of singular vortex paradoxically in a top-down manner from the surface. This precession effect on the suspended spheroid is caused externally.
Hope this information helps.
Best to you.
