SNOBA (Sun-Neptune L4 Optomechanical Baseline Array)

SNOBA — the Sun-Neptune L4 Optomechanical Baseline Array, deployed 2150–2153 by the Theoretical Physics & High-Energy Metrology Division of Luna Research Dome 1. Three free-flying, magnetically shielded metrology platforms in an equilateral triangle with a 10,000-kilometer laser-interferometric baseline, stationed 30 AU from the Sun. Built to resolve the fifteen-year deadlock following the 2139 Charon Anchor assessment and Liang Qiuyue’s 2142 propulsion framework — specifically, to detect whatever tensor-field signature the fractured Styx/Kerberos Spacer exomaterial was emitting. Instead, its 2154 results overturned the assumption that gravity is a fundamental interaction: a null result for tensor-field boson events, confirmed Verlinde Noise (holographic decoherence), and matched Verlinde’s 2016 de Sitter memory equations at a correlation of 0.9997. Reclassified GR as effective field theory; resolved Pluto instrument anomalies as Vacuum Information Sink effects ( gradients); supplied the experimental physics for Liang’s propellantless propulsion framework. Its free-space baseline became the reference for the first controlled generation of a vacuum information sink (Feb 2171): a laboratory enclosure at Dome 1 reproduced the sink signature, suppressing transverse variance by 71% ± 4% relative to the SNOBA baseline and producing relaxation events qualitatively consistent with the Styx/Kerberos anomaly record. The 2172 review restates the figures of record, including that the array’s specified resolution was and that the crossing was a differential measurement across the baseline rather than an absolute acceleration.

Figure

Correction figure for the 2172 review. Four claims as circulated, each struck through, against the figure of record. Resolution: "down to 10⁻³⁵ m" is the Planck length, entering from the factor √(ℏG/c³) in the variance expression — theory, not instrument; the array's specified resolution is ΔL/L ≈ 10⁻²⁵ over a 10⁷ m baseline, that is ΔL ≈ 10⁻¹⁸ m, and the null is an event-count limit over 36 months of live time, seventeen orders of magnitude apart. Correlation: "to eight decimal places" against ρ = 0.9997, four decimal places as given in the abstract; the phrase never appears in the paper, and this is the correction most likely to require notice by downstream authors. Acceleration: "decelerated below a₀", read as an absolute acceleration, against the figure of record — the crossing is in the differential channel, 2.9 × 10⁻¹¹ metres per second squared radial and 1.5 × 10⁻¹¹ transverse against a₀ = 1.2 × 10⁻¹⁰; the absolute heliocentric acceleration at 30 AU is 6.6 × 10⁻⁶, or 5.5 × 10⁴ × a₀, and never falls below a₀ on any trajectory. Duration: "a decade-long experiment" against deployment 2150–2153 and 36 months of continuous observation from lock in 2151; the decade in citation is the gap from the 2139 Charon Anchor assessment, not the operating record. A scope note: particulate dark matter was not falsified; the 2154 dataset establishes the a₀ term in a shielded volume at 30 AU, while galactic and cosmological universality is the framework's claim, requiring rotation-curve, cluster-mass, and acoustic-scale work.
