# stable (condition)

drift returns toward the window's centre on its own

- Computed level: L15 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [centre](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-centre.location), [return](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-return.movement), [toward](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-toward.spatial)

**Through:** The aimless drift is redirected by the window's boundary structure and actively returns toward its central location due to the stabilizing influence inherent in the system's configuration.

**Novel properties:**
- self-correction around centre
- bounded directional return
- autonomous centripetal tendency

## Examples
- The International Space Station maintains altitude through periodic reboosts after orbital decay from atmospheric drag. *(engineering)*
- A pendulum clock's bob returns to vertical after displacement, resisting external vibrations. *(physics)*
- The human inner ear corrects balance disturbances, guiding posture back to upright without conscious effort. *(biology)*
