Considering this material as an example of entrainment by harmonic resonance produces the following observations.
Harmonic cycles in the solar system that are in close numerical relation to each other, especially through duple and triple cycles, are likely to be connected to each other by resonance. The SSB/GY harmonic relation is an example of combined duple and triple cycles. The relation between these numbers is the same as the relation between a low C, a middle G and a high D in music, connected by the duple relation of the octave and the triple relation of the perfect fifth, with the low C corresponding to the precessional wobble cycle of the earth’s Great Year, the high D to the solar system barycentre, and the middle G to their point of harmonic contact in the temporal structure of the zodiacal age. G stands in 3/2 relation to both C and D. In the specific notes corresponding to the SSB/GY model, the middle G is the square root of the GY period when the SSB is the unit.
I do think it is plausible that there is a ‘lock-in’ mechanism at operation in this entrainment. To understand this we need to imagine the whole solar system as a spinning top, with myriad cycles all in harmonic relation to each other. This system is highly isolated, as far from other stars as a spinning top in the middle of a sport arena is from spectators. So, considering the celestial dynamics of the system, there is nothing more fundamental than its own gravitational cycles to produce the internal rhythms of the system. These cycles are integrated in the SSB movement, which has been shown to have a clearly defined 179 year pulse.
In this isolated long term stable dynamic structure, our solar system has a basic frequency, the SSB cycle, with a constant wave length of 179 years, while earth also has a basic frequency, the Great Year, of length 25765 years. I call the Great Year the basic frequency because its gyroscopic wobble is the main long term dynamic cycle of the earth.
I think it is highly plausible that the ‘high D’ emitted by the SSB produces a harmonic resonance in the ‘low C’ emitted by the GY to produce a ‘middle G’ in the form of the 2147 year long precessional age. Again, we can model this in musical harmonics. Setting up an organ or engine to produce a low hum in an acoustic chamber, and then playing a high note with frequency 144 times that of the low hum, it is possible to create a harmonic relation at the 12 times level, ie a high D against a low C can make a middle G.
It is well known in music that intervals of precise natural multiple frequency lock in to each other, while out of tune notes can have a shuddering dissonance.
Thinking of the earth in the maelstrom of solar dynamics, it is like our planet is tumbling through space supported by a web of interacting bodies, all of which are in an overall ‘shepherding’ relation to each other. Lunisolar precession produces 99% of the basic structure of the Great Year, but the pace of the wobble is regulated by the remaining planets, principally the JSNV 179 year SSB cycle.
