The proton's Compton wavelength sets the geometric intake capacity , and helium-4 binding sets the restoration efficiency . Their product yields to 0.06% accuracy with zero free parameters.

The theory proposes that is not a fundamental constant but the product of two independently measurable quantities:
Where:
The physical picture: spacetime exhibits a flow toward mass-energy concentrations, analogous to a fluid flowing toward a drain. The strength of this flow — gravity — is determined by (1) the geometric "intake area" of fundamental particles, and (2) the efficiency of energy restoration during nuclear binding.
The proton, as the stable baryon, sets the geometric scale for gravitational interaction. Its Compton wavelength defines its quantum interaction scale:
The proton creates a 1-dimensional cylindrical channel through time — a "temporal valley" — through which spacetime flows. The raw geometric intake per unit mass is the Compton cross-section divided by the proton mass:
This is the starting point — but three suppression factors reduce this raw intake to the tiny value of , explaining why gravity is times weaker than the strong force.
The raw geometric intake is suppressed by three independent physical mechanisms, each with a clear quantum mechanical origin:
Gravity emerges from a standing wave between past→future and future→past temporal directions. This bidirectional temporal coupling is governed by the electromagnetic fine-structure constant, entering twice (once for each direction):
This is the dominant suppression — it reduces the intake by nearly 5 orders of magnitude.
The "temporal valley" through which spacetime flows is 1-dimensional (cylindrical), not 2-dimensional (spherical). The geometric factor for a cylindrical channel is:
Gravity starts as cylindrical (at the proton) and propagates spherically (at macroscopic distances), preserving the law.
Virtual pairs in the vacuum create impedance at the proton-vacuum interface, screening the proton's effective intake area:
This is a small correction (~0.7%) but it is a real physical effect from QED vacuum polarization.

This microscopic derivation of connects directly to the Yang-Mills mass gap mechanism. The same vacuum strain from the gluon condensate that generates the mass gap also determines the proton's internal structure — which sets . The chain is:
→ Compton scale
The numerical result matches CODATA to 0.06%. All inputs are measured quantities (proton mass, , He-4 binding energy). Zero free parameters.
The physical justification for the three suppression factors (, , ) — while physically motivated — needs rigorous derivation from a Lagrangian formulation. The retrocausal standing wave mechanism requires a formal quantum field theory treatment.
The smoking gun is falsifiable with current technology. Proton structure effects on local and temporal asymmetry in gravity are testable within 10–15 years.
