FQ Graviton Fluid Dynamics: Cosmic Macro‑Vortex, Redshift Mechanism and Black Hole Accretion‑Jet Picture

Abstract While the Λ‑CDM standard cosmological model achieves considerable success in observational fitting, it still faces unresolved fundamental problems including the unknown physical nature of dark matter and dark energy, the Hubble tension, and the anisotropy of galactic recession velocities. Based on two previous phenomenological studies — the “rotating‑fly‑disk” global‑rotating universe model and the modified‑gravity model with the field‑excitation coefficient η for galactic rotation curves — this paper establishes the ontological framework of FQ graviton‑fluid dynamics. Within this framework, gravity is interpreted as a blocking‑pressure‑difference momentum‑transfer effect originating from the omnipresent graviton fluid. A strict distinction is drawn between local‑perturbation propagation inside the medium and large‑scale collective convection of fluid‑medium elements. Illustrated by the wheel‑conveyor‑belt heuristic analogy: local electromagnetic and gravitational perturbations obey the speed‑of‑light limit relative to local fluid elements; by contrast, the collective‑convection velocity of medium elements within the cosmic‑scale graviton‑fluid macro‑vortex is not bounded by this local speed‑of‑light constraint. Galactic redshift arises from genuine relative motion induced by fluid‑vortex dragging, providing a physical mechanism for galactic recession and replacing the dark‑energy hypothesis. The phenomenological field‑excitation coefficient η receives a fluid‑dynamics interpretation: η characterizes the effective blocking cross‑section of nucleon‑density‑dependent matter acting upon the graviton fluid. Compact celestial bodies (black holes) produce a saturated‑blocking “fluid‑reef” effect, which reproduces galactic rotation curves without invoking dark‑matter particles. Further, a heuristic conjecture for material decomposition and shunting inside black‑hole accretion regions is proposed: a black‑hole core is not composed of graviton fluid, but ultra‑dense nuclear remnants compressed by graviton‑fluid pressure differences. Infalling matter mostly disintegrates within the accretion region outside the event horizon. Light‑particle fragments form relativistic jets along low‑pressure bipolar channels of the macro‑vortex, while a small population of heavy atomic nuclei becomes entrained into jets via turbulence. This paper inherits established observational predictions: redshift‑deviation tests for CBRF polar‑sky fields from LSST surveys, plus statistical tests of galaxy‑spin axes from FAST neutral‑hydrogen surveys. Falsification criteria for the black‑hole‑jet conjecture are explicitly laid out. Model‑intrinsic limitations are objectively catalogued, and a roadmap for future numerical‑simulation and observational validation is provided. 摘要 Λ‑CDM标准宇宙学模型在观测拟合上取得了可观成果,但依然存在暗物质、暗能量物理本质未知、哈勃张力、星系退行速度各向异性等悬而未决的基础难题。本文基于前期两项唯象研究——“旋转飞盘”全域旋转宇宙模型、用于星系旋转曲线的场激发系数η修正引力模型,搭建FQ引力子流体动力学本体框架。 在该框架下,引力被解释为遍布全域的引力子流体带来的遮挡压差动量传递效应。研究严格区分介质内部局域扰动传播与流体介质元的大尺度集体对流行为,借助轮‑传送带类比说明:局域电磁扰动、引力扰动相对于局域流体元满足光速上限;而宇宙尺度引力子流体宏观涡旋内介质元的集体对流速度不受该局域光速约束。星系红移来自流体涡旋拖拽带来的真实相对运动,为星系退行提供物理机制,替代暗能量假说。 唯象层面的场激发系数η获得流体动力学释义:η表征由核子密度决定的物质对引力子流体的有效遮挡截面。致密天体(黑洞)产生饱和遮挡的“流体礁”效应,无需引入暗物质粒子即可复现星系旋转曲线。同时提出黑洞吸积区域物质拆分分流的启发性猜想:黑洞核心并非引力子流体构成,而是由引力子流体压差压缩形成的超高密度核残余;下落物质大多在事件视界外的吸积区域解体,轻粒子碎片沿着宏观涡旋低压双极通道形成相对论喷流,少量重原子核在湍流裹挟下一并进入喷流。 本文延续已有可观测预言:LSST巡天对CBRF极天区红移偏差检验、FAST中性氢巡天开展星系自转轴统计检验,明确给出黑洞喷流猜想的证伪判据,客观罗列模型自身局限,并给出后续数值模拟与观测验证的研究路线。
