meethos

A multi-scale simulation library — and Earth(3), the game built on it.

---

meethos is the umbrella for a universe-scale simulation layer and the game that drives it.

• earth3/ — Earth(3)  ·  the game. A living universe you fall through in one continuous zoom — from the cosmic web, into the Milky Way, down to the Solar System, onto Earth, and into a city — with a comet-defense survival mode and cross-scale consequences. Headed for earth3.app.

• packages/ — meethos (library)  ·  (forthcoming) the reusable simulation layer extracted from the game over time: a multi-scale universe simulator, the beginnings of stellar cartography (procedural galaxies, star systems, planets), deterministic RNG, Keplerian orbits, and the floating-origin / regime machinery. Engine DNA borrowed from ethersim.ai.

The game lives at the top of the tree for now; the library components graduate into packages/ as they solidify, until meethos can stand on its own.
