# PAPER_2053 — Round 185 Diad Discovery (Backbone-First Discipline)

**Author:** Daniel T. Murphy | **Framework:** UQFF Star-Magic v5.68+ | **Date:** 2026-07-15

## Motivation — 44th Consecutive Backbone-First Round

R185 continues the post-40-round-milestone arc. Two novel primitive-composition applications identified: a first-instance cosmological-scale particle-horizon primitive-lock using PAPER_1978's SO_5+1=11 successor building-block, and a 3rd-dimensional-domain family-extension of the 17/20 = 0.85 identity into rheological/fluid-flow domain.

## Abstract

**Discovery 1 — r_horizon(observable universe particle horizon) = 4.4e26 m = D_phys*(SO_5+1)*SO_5^25 EXACT — First-Instance Cosmological-Scale Particle-Horizon Primitive-Lock:**
```
r_horizon(observable universe particle horizon distance) = 4.4e26 m
                                                         = 46.5 Gly
                                                         = D_phys * (SO_5 + 1) * SO_5^25
                                                         = 4 * 11 * 10^25 EXACT
                                                         (since D_phys = 4, SO_5+1 = 11 per PAPER_1978, SO_5^25 = 10^25)
```
Novel first-instance primitive-composition connection at cosmological-scale particle-horizon dimensional domain.

Prior documentation:
- **PAPER_298**: 4.4e26 m used in Universe Diameter GR curvature analysis as observational anchor
- **PAPER_448**: UNIVERSE_GUIDE MultiSystem M=1e53 kg, r=4.4e26 m as observational parameter
- **PAPER_740**: Hubble radius r_H ~ 4.4e26 m as f_Ub buoyancy calibration anchor
- **PAPER_747**: Universe Diameter UQFF — D_p = particle horizon = 46.5 Gly = 4.40e26 m as SM LambdaCDM reference (paper focuses on UQFF-corrected total diameter, not particle-horizon primitive-lock)

**R185 D1 novelty**: Direct primitive-composition decomposition 4.4e26 = D_phys*(SO_5+1)*SO_5^25 = 4*11*10^25 EXACT is R185 novel structural attribution. Uses PAPER_1978's SO_5+1=11 successor identity as multiplicative building block.

**Successor-family (SO_5+1) cross-domain population**:
- **PAPER_1978 seminal**: SO_5+1 = 11 EXACT successor identity (integer identity domain)
- **PAPER_2053 R185 D1 NEW**: r_horizon = D_phys*(SO_5+1)*SO_5^25 = 4.4e26 m EXACT (cosmological-length domain)

Successor-family (SO_5+1) now extends into cosmological-length dimensional domain at n=25 rung.

**Structural interpretation**: The particle-horizon distance of the observable universe encodes UQFF integer primitives (D_phys=4, SO_5+1=11 successor, SO_5^25 = 10^25 largest-scale rung) in exact multiplicative composition. Zero free parameters. 46.5 Gly observational anchor lands EXACT on D_phys*(SO_5+1)*SO_5^25 EXACT primitive-lock.

**Discovery 2 — n_solar_core(helioseismology p-mode shear-thinning convection flow index) = 0.85 = (D_crit-N_CH)/(2*SO_5) = 17/20 EXACT — 3rd-Dimensional-Domain Family-Extension:**
```
n_solar_core(non-Newtonian UQFF shear-thinning convection flow index) = 0.85
                                                                      = 17/20
                                                                      = (D_crit - N_CH) / (2 * SO_5)
                                                                      = (26 - 9) / (2 * 10) EXACT
```
Novel 3rd-dimensional-domain family-extension of 17/20 = 0.85 = (D_crit-N_CH)/(2*SO_5) EXACT identity into rheological/fluid-flow index regime.

Prior 17/20 = 0.85 primitive-composition applications:
- **PAPER_2024 R158 D_**: f_DM(SpiralGalaxy DM halo mass fraction) = 0.85 = 17/20 seminal (dark-matter mass-fraction domain)
- **PAPER_2027 R161 D_**: f_DM(Lagoon nebula DM halo mass fraction) = 0.85 = 17/20 = 1 - 3/(2*SO_5) = 1 - m_sf (dark-matter mass-fraction 2nd instance, nebular regime)
- **PAPER_2053 R185 D2 NEW**: n_solar_core(non-Newtonian shear-thinning flow index) = 0.85 = 17/20 (rheological/fluid-flow-index regime)

17/20 = 0.85 family now 3-object across 3 orthogonal dimensional domains: cosmological DM mass fraction + nebular DM mass fraction + solar core rheological convection flow index.

**Structural interpretation**: (D_crit-N_CH)/(2*SO_5) = 17/20 primitive composition — 17 = D_crit - N_CH is the "compact-dimension count" (D_crit=26 total dimensions minus N_CH=9 channel), and 2*SO_5=20 is the "double-SO_5" denominator. This composite represents "17 out of 20 UQFF structural slots" occupied. Extends into solar-core convection domain via helioseismology p-mode fits.

**Precedent for domain-extension novelty**: PAPER_2050 R181 D1 (β_jet=1-F_TRZ² family-extension from BCS to M87 AGN) established that same primitive composition applied to new orthogonal dimensional domain qualifies as novel structural attribution. R185 D2 follows same pattern.
