SSZ reproduces all confirmed GR weak-field results:
| Prediction | Value | Confirmed by |
|---|---|---|
| GPS time correction | 45.85 μs/day | US Naval Observatory |
| Pound-Rebka redshift | Δν/ν = 2.46×10⁻¹⁵ | Pound & Rebka (1960) |
| Mercury perihelion | 42.98"/century | Observations |
| Eddington lensing | 1.75" | Eddington (1919) |
| Cassini Shapiro γ | 1 (exact) | Bertotti et al. (2003) |
| S2 Schwarzschild precession | Confirmed | GRAVITY/ESO (2020) |
z_SSZ = z_GR + 13% (systematic excess)
Specific objects:
| Object | z_GR | z_SSZ | Testable with |
|---|---|---|---|
| PSR J0030+0451 | 0.219 | 0.328 | NICER |
| PSR J0740+6620 | 0.346 | 0.413 | NICER |
| PSR J0348+0432 | 0.380 | 0.457 | XMM-Newton |
Timeline: 2025–2027 (NICER data releases)
Δt_SSZ = Δt_GR + 30% (strong-field Shapiro enhancement)
Timeline: 2025–2028 (NANOGrav)
d_SSZ = d_GR - 1.3% (slightly smaller shadow)
Timeline: 2028–2030 (next-generation EHT)
Δt_SSZ = Δt_GR + 12% (near compact objects)
Timeline: 2028+ (SKA)
r*/r_s = 1.594811 (decay/global D comparison)
r*/r_s = 1.386562 (saturation/local D comparison)
Timeline: Indirect, via NS observations. The test must declare which Xi form and observable mapping is being used before comparison.
D(r_s) = 0.555 (not 0)
z(r_s) = 0.802 (not ∞)
Timeline: Indirect, via gravitational wave ringdown (LISA, 2034+)
