The Metabolic Universe: A Research Program

This program proposes that supermassive black holes are not terminal gravitational sinks but cyclic metabolic processors. Matter that falls toward them is dismantled into its subatomic baseline; the resulting three-dimensional volume information is compressed onto a two-dimensional horizon boundary; and the accumulated material is periodically exhaled back into the host galaxy along radial thermal filaments. The exhaled filaments cool, condense, and dissolve, dumping refined heavy elements into the surrounding molecular clouds, where they seed the next generation of star formation. The cycle — eat, shred, compress, vent, cool, seed — is closed, and it has been running for billions of years. The program rests on three pillars. First, a 3D Spatial Attachment Matrix: space is modeled not as a flat background with a superimposed flow, but as a coordinate structure intrinsically anchored to and deformed by the central engine. The River Model of general relativity (Hamilton & Lisle 2008; Visser & Liberati 2022) provides the mathematical backbone, and the Kerr twist vector emerges as a natural consequence of attachment to a spinning core. Second, a substrate field: a massless scalar Φ_substrate coupled to the electromagnetic sector via the axion-like term g_Φγ Φ_substrate F_μν F^μν, with g_Φγ ≲ 10⁻¹⁰ GeV⁻¹. Third, the Eddington-Metabolic Inversion (EMI): a dimensionally consistent thermodynamic phase transition at which a sufficiently overfed core stops accreting and begins to vent, with a critical threshold of Ṁ_crit = 2.5 × 10⁻⁴ solar masses per year for a Sgr A*-mass SMBH. The program produces specific, falsifiable numbers. If structural shredding occurs at the roots of Sgr A*'s horizontal filaments, JWST NIRSpec Integral Field Unit spectroscopy should reveal four simultaneous signatures: a ≥10× drop-off in H₂ 1-0 S(1) surface brightness over 0.3 ± 0.2 pc; a 3–10× enhancement in the [Fe II]/[Ne II] ratio; a spatial anticorrelation between PAH 3.3 μm emission and [Fe II] at ≥2σ; and Br-α line broadening 2–5× the filament body value. Non-detection of all four falsifies the structural shredding hypothesis. The suite consists of six documents — three technical papers with plain-language companions — organized as three groups: QLT (mathematical formalization), SAGA (framework and predictions), and LC (comparative mapping). The program is explicitly an alternative interpretive and phenomenological framework, not a replacement for general relativity, quantum field theory, or ΛCDM. Where the framework makes empirical claims, they are labeled and quantified; where it makes interpretive claims, they are labeled. This is a self-published independent research program. It has not been peer reviewed, has not been submitted to any journal, and is not affiliated with any institution. The author does not seek conventional academic validation and does not require it for the framework to be considered on its merits. Standard physics is referenced and appreciated where it is relevant, but the framework is novel in many of its claims and is, in substantial part, unproven. That is the nature of new ideas. The predictions are specific, the falsification conditions are stated, and any reader — inside or outside the academy — is invited to test, critique, extend, or refute the framework. Corrections and refutations are welcomed. Silence is not. The universe breathes. We are inside one of its breaths.
