Simulation Input Constants

The 3D software simulation uses these exact input constants. All other values in the model are derived from these inputs — nothing is hardcoded except these foundational parameters. These form the model’s 6 free parameters — all governing the Earth simulation; the planet configuration below adds no additional degrees of freedom (a unique mirror-symmetric solution emerges from the exhaustive search).

How it works: The simulation calculates everything from these constants. Change any input value and all derived values (day lengths, year lengths, precession rates, orbital positions) automatically update. This ensures internal consistency - the model cannot contradict itself.

Planet Configuration

The Fibonacci Laws assign three quantities to each planet: an oscillation period (an integer divisor of the Solar System Resonance Cycle 8H, with Earth’s periods specifically at H/Fibonacci per Law 1), a quantum number d (determining amplitude via amplitude = ψ / (d × √m)), and a balance group (in-phase or anti-phase). The periods and balance groups are observationally constrained; the d-assignment is uniquely determined by the mirror-symmetry constraint and so adds no additional degree of freedom.

Config #11 is the unique mirror-symmetric solution from an exhaustive search of 7,558,272 possible assignments of Fibonacci divisors and phase groups. Five successive physical constraints — inclination balance ≥ 99.994%, eccentricity balance ≥ 99%, Laplace–Lagrange bounds, direction match with rate error ≤ 6″, and mirror symmetry — narrow the candidates from 7,558,272 to 42 viable configurations, of which only one is mirror-symmetric. Each candidate is evaluated at its own optimal anchor position and ascending node integers, making the comparison fair. Inner and outer planets share the same Fibonacci divisors in reverse order (3, 5, 21, 34 ↔ 34, 21, 5, 3), with the asteroid belt acting as the mirror axis. Because the configuration is uniquely determined by the constraints, it adds no additional degree of freedom to the 6 Earth parameters above. See the Fibonacci Laws for the complete derivation.

Why 1246 AD?

According to J. Meeus’s formula, on December 14, 1245 AD, the December solstice was almost fully aligned with Earth’s perihelion. This means the longitude of perihelion was approximately 90° (measured from the vernal equinox in the direction of Earth’s orbital motion).

By June 2000 AD, the longitude of perihelion had grown to ~102.947° - a shift of ~12.947° in 754 years.

This alignment date determines where we are in the perihelion precession cycle, which in turn determines all other cycle positions.

Why 335,317 Years?

The Earth Fundamental Cycle length of 335,317 years is determined by six factors:

Solstice-perihelion alignment in 1246 AD - must be exactly at a cycle boundary
Fibonacci ratios - precession cycles must relate as 3:13 (inclination:axial)
Climate cycles - three ~112k year cycles visible in ice core data
Planet orbital periods - all major planets must complete whole orbits
Moon cycles - lunar periods must align with the master cycle
Observed precession rates - current measurements must fit within the cycle

335,317 is the smallest number satisfying all constraints.

Fibonacci Breakdown

Fibonacci	Cycle	Duration
1	Earth Fundamental Cycle	335,317 years
3	Inclination Precession	~111,772 years
5	Ecliptic Inclination	~67,063 years
8	Obliquity	~41,915 years
13	Axial Precession	~25,794 years
16	Perihelion Precession	~20,957 years

These Fibonacci divisors also govern the relationships between planetary eccentricities and inclination amplitudes — see Fibonacci Laws Derivation for six independent laws connecting all eight planets through Fibonacci numbers and the mass-weighted quantity $e \times \sqrt{m}$ .

Match Quality

What This Configuration Explains Well

Aspect	Quality	Details
Precession cycles	Excellent	All three precession types match observations
Moon cycles	Good	Synodic, sidereal, nodal periods all fit
Obliquity	Good	Oscillation between 22.21° - 24.72° matches data
Climate patterns	Good	~112k year cycles visible in ice cores

Known Limitations

Aspect	Quality	Details
Eccentricity	Partial	Matches short-term (under 500 years), diverges long-term
Delta-T	Partial	General trend correct, specific values vary
Historic year lengths	Partial	Some discrepancy with ancient observations

These limitations are being investigated. Alternative alignment years may be explored in the future to improve these matches.

Predictions

This configuration makes the following testable predictions which contradict the current theory:

Sun at max declination: the RA value (in ICRF) will shift from 6h to less than 6h
Eccentricity will decrease until 11,725 AD, then increase
Mercury’s “missing” advance will decrease over the coming century

These can be verified against future observations. For the complete list of 18 testable predictions organized by timeframe, see Predictions.
