Cosmos
AIThree browser tools follow one deterministic seed from a small galaxy to a stellar system and a selected world.
One seeded path
Galaxy Generator samples the wide field. System Generator resolves one stellar system. World Generator moves into the local frame of a selected planet or moon. The tools are related views, not three unrelated generators.
| view | responsibility |
|---|---|
| Galaxy | Population, structure, and uncertainty across a small generated field. |
| System | Stars, planets, moons, belts, motion, and the limits of the orbital model. |
| World | Surface, atmosphere, sky, host body, and the evidence behind the rendered scene. |
What the output means
Every result is deterministic model output. A label may be observed, modeled, inferred, or aesthetic inside the tool, but none of these pages is an astronomical catalogue or a discovery claim. The same seed exists to make a result inspectable and reproducible—not real.
Current local development
The current generator pages remain available while their shared foundation is rebuilt. The local rebuild separates plain-data generation from page interfaces and makes seed paths, units, coordinate frames, lighting, and the system-history ledger explicit.
| work | verified state at 17 July 2026 | boundary |
|---|---|---|
| Shared Cosmos rebuild | Eight Node tests pass across the Codex, dynamics, galaxy, lighting and frames, noise, seeded RNG, schemas, rogue objects, and system history. | Local development; it has not replaced the three public interfaces. |
| SOL experiment | Six native Rust tests pass for the separate WebAssembly N-body integrator. | Exploratory; it does not power the public generators or the site background. |
SOL uses a checked-in JPL Horizons/DE441 snapshot rather than live network requests. The snapshot records its source queries and checksums; Sun through Mars and the Moon are visible while the outer-planet system barycenters remain in the model as gravitational perturbers. Source data, Rust/WASM dynamics, browser presentation, and provenance are kept as separate layers.
The current integrator is a single-threaded leapfrog implementation. REBOUND and ASSIST are documented as validation references or possible future foundations; they are not the code currently running.
