Hello GHMB,

Last year I proposed the idea of 'Spiral Precession' whereby the Earth's polar axis - rather than tracing a simple circle of c.26,000 years as the conventional view of Lunisolar precession states - the polar axis actually traces a double-spiral as in the image below:

 

The above is substantially different from my previous proposal whereby the Earth would completely tip over after a long period of time (see below):

PREVIOUS HYPOTHESIS:

Spiral precession would explain the apparent accelerating rate of precession as each cycle of the precessional spiral becomes an ever decreasing circle (i.e. ever decreasing coils in the spiral).

Spiral precession would also offer an explanation for the change in the Earth's obliquity and, the accelerating rate of change to the obliquity as the polar axis traces ever tightening coils at the top of the spiral. This might explain the longer periods of glaciation (c.80,000 years) to declatiation (c.20,000 years). And depending how the spiral tapers this could also explain the rapid entry of the Earth into glacial periods and the rapid exit into inter-glacials (see glaciation chart below):

Two (glacial) troughs in the graph above represent each end of the double-spiral with the inter-glacial peaks corresponding to the 'bulge' of the spiral coil.

And finally, spiral precession in utilising the 'Law of Phi' keeps the Earth's Third Motion in harmony with everything in nature:

Spiral Precession may offer a simpler alternative to Milankovitch cycles that present a theoretical model for the Earth's 'clockwork' glacial/inter-glacial periods.

Happy to hear your (constructive) thoughts as I know this particular topic is of interest to a number of people here on GHMB.

Regards,

Scott Creighton
