Abstract

The runaway supermassive black hole RBH-1 ($z \approx 0.96$) presents a thermal paradox: JWST spectroscopy reveals a 650 km/s velocity discontinuity coexisting with cold, star-forming gas. Standard shock physics predicts post-shock temperatures $T \sim 10^7$ K, yielding a cooling time that exceeds the dynamical time by a factor of ~30. Yet the wake exhibits immediate star formation and extreme collimation (50:1 aspect ratio over 62 kpc).

An alternative interpretation is proposed: RBH-1 is analyzed as a gravitational soliton—a coherent region of altered proper-time rate. The observed velocity discontinuity is modeled as a metric shock (spatial gradient in gravitational redshift) rather than bulk thermalization. The effective Jeans mass is reduced behind the front via time dilation, enabling immediate star formation without requiring extreme heating.

The model's geometric scale contains no free parameters. The soliton radius is fixed by the saturation density $\rho_c \approx 20$ g/cm³, independently derived from terrestrial GNSS correlations (Smawfield 2025g). Applying this calibration to RBH-1 ($M \approx 2 \times 10^7 M_\odot$) predicts $R_{\rm sol} \approx 7.8 \times 10^7$ km $\approx 1.3 R_S$, allowing the wake interaction scale to serve as a decisive test of the soliton hypothesis for this object. Specific falsification criteria are outlined; decisive discrimination awaits line-profile decomposition and X-ray flux limits.

Key Findings

RBH-1 (z ≈ 0.96) presents a thermal paradox: a 650 km/s velocity discontinuity coexists with cold, star-forming gas, yet standard shock physics predicts T ~ 10⁷ K requiring ~30× cooling time. JWST NIRSpec [O III] spectroscopy reveals narrow line widths (σ ~ 30 km/s vs expected ~85 km/s for thermal shock), supporting a cold "metric shock" interpretation rather than thermal shock. The soliton model predicts R_sol ≈ 1.3 R_S with no free parameters—the scale is fixed by the universal critical density ρ_c ≈ 20 g/cm³ calibrated from terrestrial GNSS correlations. This parameter-free prediction enables direct falsification via mass determination, X-ray flux limits, and line-profile decomposition.

Theoretical Framework

This work builds on the Temporal Equivalence Principle (TEP), which proposes:

• Gravity is Geometry; Time is a Dynamical Field.
• The decomposition of proper time accumulation into "mass" and "time dilation" is gauge-dependent.
• Sector Decoupling: The Conformal Sector (clock rates) is unconstrained by GW170817, while the Disformal Sector (speed of transmission) is tightly bound.
• Soliton Solutions: The non-linear kinetic structure supports coherent field configurations ("Time Stars"), allowing for the macroscopic phenomenology observed in RBH-1.
