Free-Fall as a Dual-Dimensional Observable

Earth surface gravity is derived from a five-step pure lattice chain. The G1 and G2 register values are related exactly by g_G2/g_G1 = √(1+δ_G) — the same G-bond mechanism as the equatorial radius.

From Pure Lattice to Earth's Free Fall

The Universal Force of Time framework derives Earth's free-fall acceleration — what science calls gravity — from first principles without any empirical fitting. The chain starts from a pure lattice value and passes through five arithmetic operations, all of which use only the prime lattice {2, 3, 5, π}:

P-GRAV-DD-1 — The Five Steps (G1 Register)
Step 1:  G1_start = 3π/4 × 10 = 23.561944902...
Step 2:  × 4π²/10  →  AU_G1 = 93.126... million miles
Step 3:  × 5⁵/(2³×3⁵)  →  AU_G1 = 149.768... million km
Step 4:  × 2 ÷ 360 ÷ 864 × 10⁵  →  g² = 96.147...
Step 5:  √  →  g_G1 = 9.805487563... m/s²
Step 3 uses km/miles = Sun×Mercury = 5⁵/(2³×3⁵) — see P-PSD-2.

g_G2 / g_G1 = √(1+δ_G) exactly

The G-bond step δ_G = 90.1506 ppm governs the separation between the G1 and G2 temporal registers. It is defined as the ratio of the two Moho radii:

G-Bond Definition
Moho_G2 = 20,000,000/π m
Moho_G1 = 2⁹×3⁹×π²/5⁶ km × 1000
δ_G = Moho_G2 / Moho_G1 − 1 = 90.1506 ppm

Since g ∝ √AU and AU(G2)/AU(G1) = (1+δ_G) exactly, the register ratio of free-fall accelerations follows algebraically:

P-GRAV-DD-4 — Register Ratio
g_G2 / g_G1 = √(1+δ_G) [exact — algebraic identity]
g_G1 = 9.805487563148... m/s²
g_G2 = 9.805929539... m/s²
Residual: < 10⁻¹⁵ (machine precision zero)
The same δ_G governs the equatorial radius split (FOT_EarthDualDimensional.pdf) and the sidereal day split.

The Earth–Sun Distance in Two Registers

The AU itself is a dual-dimensional observable. The G1 and G2 starting values produce two register-conjugate Earth–Sun distances whose ratio is exactly (1+δ_G):

P-GRAV-DD-5 — Dual AU
AU_G1 = 149.768... million km
AU_G2 = 149.782... million km
AU_G2 / AU_G1 = (1+δ_G) [exact]
IAU standard AU = 149.5978707 million km (geometric mean of G1 and G2)

Key Results

P-GRAV-DD-1

Earth surface free-fall is derived from a five-step pure lattice chain starting from G1_start = 3π/4 × 10 = 23.561944902... The chain uses only {2,3,5,π} arithmetic.

P-GRAV-DD-2

Step 3 of the chain uses km/miles = 5⁵/(2³×3⁵) = Sun×Mercury dimensional speed product. Planetary spacetime speeds are therefore embedded in Earth surface gravity.

P-GRAV-DD-3

The G1 register starting value 3π/4 × 10 simultaneously encodes Mercury quarter-orbit geometry (3π/4 = 135° in radians) and the AU scaling factor.

P-GRAV-DD-4

g_G2/g_G1 = √(1+δ_G) exactly. This is an algebraic identity following from g ∝ √AU and AU(G2)/AU(G1) = (1+δ_G). Residual is machine-precision zero.

P-GRAV-DD-5

AU(G2)/AU(G1) = (1+δ_G) exactly. The Earth–Sun distance exists in dual-dimensional form; their geometric mean equals the IAU 2012 standard AU.

P-GRAV-DD-6

G-bond step δ_G = 90.1506 ppm is the universal register separation constant. It appears identically in the equatorial radius split, the sidereal day split, the free-fall ratio, and the Mercury spin-orbit ratio.

P-GRAV-DD-7

g_G1 = 9.805487563... m/s² (G1 register, lower Moho anchor). g_G2 = 9.805929539... m/s² (G2 register, observed ground-level value). Deviation from ISO standard g (9.80665): 73.4 ppm.
