Each simulated star is an identity with torsion τ = B/P, placed against the Universal Torsion Limit TL = 0.136899099984016. The simulator layers measured galactic physics onto that placement in four switchable stages: a static snapshot, a disk rotating on a measured flat rotation curve, a Lin–Shu density wave, and live Newtonian self-gravity with stellar fusion governed by the 2-beam rule of the GAM Collider (Geometric Axiomatic Module Collider). A τ-model toggle replaces the generator's phase bands with τ = TL/Q, where Q is the Toomre stability parameter, by identifying the Toomre boundary Q = 1 with τ = TL. Every stage can be switched on and off during a run, so each layer's effect is visible against the one beneath it. Worked examples reproduce the winding problem, the persistence of density-wave arms, the reversal of arm crossings at corotation, the stability of the Milky Way disk, the fragmentation of a cold disk into clumps, and the self-regulation of a stellar disk back toward stability. This guide walks through each control and readout, gives worked examples with the numbers the simulator produces, states the scope of each stage, and lists applications for students, teachers and researchers. --- ## Overview Galaxy™ answers a visual question: what does a disk of identities look like when the forces that shape real galaxies are switched on one at a time? The simulator has four layers, each a toggle: 1. **Snapshot (F_ext = 0).** Shots settle by their PNBA values into a frozen disk. 2. **Rotation.** The disk turns on a measured flat rotation curve, either by rotation alone or with a density wave holding two or four arms. 3. **τ = TL/Q.** Each star takes its torsion from the Toomre stability of the disk at its radius. 4. **Gravity.** Stars pull on each other, gather into clumps where the disk is locally unstable, and fuse by the GAM Collider rule. Readouts on the right report the phase mix with its statistical error band, the phase profile by radius with the mean τ in each ring, the rotation curve, the clock in millions of years, and, when gravity is on, the clumps that form. Galaxy™ runs at uuia app/galaxy as one self-contained HTML (HyperText Markup Language) file. It needs no installation and no account, and it works in any current browser on a desktop, tablet or phone. --- ## 1. Grounding ### 1.1 The Torsion Limit The Universal Torsion Limit is TL = 0.136899099984016. The Sovereign Anchor Constant is Ω₀ = TL × 10 = 1.36899099984016. The fine-structure constant follows from TL: subtracting one TL from the CODATA (Committee on Data of the International Science Council) 2018 value 1/α = 137.035999084 leaves 136
