RBH‑1 as a Perpetual Surfer: Recoil of Space‑Phase and the Black Hole as a Passive Passenger

Runaway Black Hole 1 (RBH‑1) is typically interpreted as a compact object that received agravitational‑wave recoil (“kick”) during a merger and subsequently generated a bow shock andstar‑forming wake while moving through ambient gas. In this paper we adopt a stronger SP3interpretation: the recoil occurs within the space‑phase fabric itself, and the black hole is apassive passenger embedded in a propagating space‑phase wave. The feature identifiedobservationally as a bow shock is reinterpreted as the leading space‑phase envelope of thisrecoiling fabric, which conditions matter ahead of the black hole’s motion. RBH‑1 follows behindthis envelope in a Perpetual Surfer configuration, while the luminous trail is understood as aspace‑phase memory track rather than hydrodynamic debris. This framework unifiesgravitational‑wave recoil, guidance, wake coherence, and persistence into a single medium‑levelprocess and suggests concrete observational discriminators between shock‑only andspace‑phase‑wave interpretations.
