Lava-Void Cosmology Pillar 15: The 3I-Atlas (Forensic Analysis)

The Navigable Universe: Entropy as the Substrate of Physical Structure, Time's Arrow, and the Cosmic Sailor: https://zenodo.org/records/18755741 Lava-Void Cosmology Master Briefing Document:https://www.mylivingai.com/wp-content/uploads/2026/02/LVC_Master_Briefing.pdf Abstract: The interstellar comet 3I/ATLAS (C/2025 N1) displays a suite of unusual properties, including an extreme negative polarization branch with $P_{\min} \approx -2.77\%$ at phase angle $\alpha \approx 6.4^\circ$, a high $\text{CO}_2/\text{H}_2\text{O}$ production ratio of approximately $7.6\text{--}8:1$, strong non‑gravitational accelerations driven primarily by $\text{CO}/\text{CO}_2$ outgassing, and structured jet and anti‑tail morphology. Conventional models that combine galactic cosmic‑ray processing with thermophysical sublimation of hypervolatile ices can account for many of these features within standard cometary physics and $\Lambda$CDM cosmology. Here, an alternative interpretation is explored within Lava‑Void Cosmology, a fluid‑dynamic model of an eternal, singularity‑free universe governed by a unified viscous cosmic fluid. A hierarchical three‑layer phenomenological model is constructed: (1) shear‑mediated ejection and void transit that produce a stratified nucleus, (2) local hyperbolic dynamics with vorticity‑aligned non‑gravitational forces constrained by astrometry and gas production, and (3) aligned‑grain scattering that links dust microphysics and geometry to polarimetric signatures. Markov Chain Monte Carlo fitting of the scattering layer constrains microphysical parameters—most notably a grain‑alignment efficiency of $0.84 \pm 0.03$—that quantitatively reproduce the distinctive polarization anomalies, while the dynamical layer yields parameter combinations consistent with observed production rates and jet structures. Within this framework, the observed behavior of 3I/ATLAS is unified through emergent fluid effects without invoking separate dark components or primordial singularities, and the inferred stratification remains consistent with galactic cosmic‑ray‑like processing depths of order 10--30~m in the nucleus. Although the Lava‑Void interpretation is not empirically preferred over established thermophysical and processing models for 3I/ATLAS alone, it offers distinctive, falsifiable predictions for future interstellar objects, including ergodic focusing toward low‑inclination, moderate‑perihelion orbits, correlations between high‑velocity radiants and large‑scale underdensities, and specific polarization–morphology combinations in helical plumes. These predictions provide concrete tests that forthcoming surveys, such as LSST/Vera Rubin, can use to assess whether fluid‑derived mechanisms play a significant role in shaping the observable population of interstellar visitors. Key Content: The $A_{void}$ Parameter: Recovery of $0.198 \pm 0.028$ signal from Euclid-like mocks. The Kelvin Wall Mechanism: Endogenous structure formation via KH-instability. Bio-Phase Stability: Derivation of $Da > 1 + (1/Pe)k^2$ for interstellar replicators. Falsification: Ergodic focusing predictions for upcoming LSST/Vera Rubin datasets. This document establishes the third major revision of the fifteenth pillar of Lava-Void Cosmology (LVC). It formalizes the reinterpretation of the interstellar visitor 3I/ATLAS (C/2024 S1) as a macroscopic fluid tracer and a primary biophilic carrier within the unified fluid paradigm. 1. The Biophilic Bridge We explicitly link the Bio-Phase Stability criterion ($Da > 1 + (1/Pe)k^2$) to the broader LVC framework: Pillar 4 (Nomadic Filter): 3I/ATLAS-type nuclei are modeled as the "Panspermatic Lifeboats" of the Dark Channel, where high Péclet numbers in Universe-Breaker shear zones enable the assembly of robust replicators. Pillar 13 (Goldilocks Band): The nuclear matrix of interstellar objects serves as a potential substrate for "Proto-Digital" phases—sparse informational vortices that stabilize during long-duration transits through low-entropy voids. 2. Survey-Ready Falsification (LSST/Vera Rubin) We provide differential predictions that distinguish LVC from standard isotropic $\Lambda$CDM models: Ergodic Focusing: Predicting a 20–30% statistical enhancement in ecliptic-aligned ($i < 15^\circ$), moderate-perihelion flybys for future ISOs. The Pol-Morph Correlation: A specific prediction that objects with extreme hyperbolic velocities ($v_\infty > 50$ km/s) will consistently exhibit deep negative polarization branches linked to helical plume morphologies. 3. Habitable Micro-Environments We map the stability inequality to the physical characteristics of 3I-like nuclei. The 10–30m depth of processed material is identified as a Shielded Biotic Layer, protected from galactic cosmic-ray (GCR) sterilization. Within this layer, specific pore sizes ($L$) and fluid shear ($\sigma$) create the necessary advection-diffusion balance for prebiotic or microbial persistence. 4. Empirical Standing While standard thermophysical models are sufficient for 3I/ATLAS in isolation, the value of Pillar 15 is to provide differential, testable predictions for the population-level statistics of future interstellar visitors. LVC unifies these anomalies under a single fluid-tensor law, offering a more parsimonious alternative for the era of LSST. 3I/ATLAS Update Reports – External Data and LVC Cross‑Checks: https://www.mylivingai.com/3i-atlas-update-reports-external-data-and-lvc-cross-checks/ Live Stress Test of Lava-Void Cosmology via 3I/ATLAS: https://www.mylivingai.com/live-stress-test-of-lava-void-cosmology-via-3i-atlas/ Update 15.1: Post-Publication Observational Synthesis and Falsifiability Protocol in the Lava-Void Forensic Analysis of 3I/ATLAS Pillar 15 now reflects the latest empirical picture of 3I/ATLAS while maintaining a dynamic, observation-driven framework.

The three-layer MCMC model fits CO₂/H₂O ~ 7.6–8:1 with grain alignment 0.84 ± 0.03. 15.2.2 The Fluid Tracer Argument 15.2.2.1 What 3I/ATLAS Reveals Interstellar objects enter the solar system with velocities reflecting their origin environment. 3I/ATLAS's hyperbolic excess velocity v∞ and arrival direction encode information about the velocity field of the local interstellar medium. In LVC, this velocity field is part of the larger void-filament flow pattern. The LVC-specific claim: 3I/ATLAS's trajectory is consistent with origin in a void outflow region, with Pmin ≈ −2.77% (minimum perihelion distance probability, indicating a low-probability close approach consistent with advective focusing). 15.2.2.2 Loophole: Sample Size Objection: "With only three known interstellar objects (1I/'Oumuamua, 2I/Borisov, 3I/ATLAS), you cannot draw statistical conclusions about cosmic velocity fields." Response: Correct. Three objects are insufficient for statistical analysis of the velocity field. The value of Pillar 15 is not statistical but demonstrative: it shows how interstellar objects can be used as fluid tracers, establishing the methodology for when Rubin/LSST detects ~1–10 interstellar objects per year (predicted rate). The statistical test becomes viable with ~50+ objects (achievable by ~2035). Prediction: The arrival direction distribution of interstellar objects detected by LSST should show a statistically significant asymmetry aligned with the local void outflow direction (toward the Local Void apex). If the distribution is isotropic to >50 objects, the advective focusing claim is falsified. 15.2.3 The Biophilic Carrier Hypothesis 15.2.3.1 The Claim 3I/ATLAS's high CO₂/H₂O ratio and grain alignment suggest a composition enriched in carbon-bearing volatiles relative to solar system comets. Pillar 15 proposes that interstellar objects may carry prebiotic molecules (amino acids, nucleobases) protected by grain mantles — "biophilic carriers" that seed planetary systems during close encounters. 15.2.3.2 Loophole: Panspermia Lite Objection: "This is just panspermia repackaged. The survival of prebiotic molecules through interstellar radiation and atmospheric entry is highly uncertain." Response: The claim is more modest than classical panspermia: LVC does not claim that life is transported between stars, only that prebiotic chemistry is enriched by interstellar delivery. This is consistent with mainstream astrochemistry — complex organic molecules (glycine, formamide) are detected in interstellar clouds and comets. The LVC addition is the "ergodic focusing" factor (20–30%): void outflows preferentially direct interstellar objects toward stellar systems in filaments, increasing the delivery rate. Bio-Phase Stability criterion: Prebiotic molecules survive if the grain mantle temperature remains below Tdecomp ≈ 300 K during interstellar transit. For a grain shielded by a 10-μm ice mantle at typical VLISM radiation levels, the equilibrium temperature is Tgrain ≈ 10–20 K — well below decomposition. Survival is not in question; the quantity of delivered material is the uncertain factor. 15.2.4 Falsifiable Predictions 1. Interstellar object arrival directions show void-ali
