# possibility (potential)

A window that can be reached from the current window without crossing a wall that is closed.

- Computed level: L14 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: abstract

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [close](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-close.spatial), [cross](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-cross.symbol), [current](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-current.fluid), [reach](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-reach.spatial)

**Through:** The components together describe how unimpeded change along a parameter can allow movement from one bounded state to another through an open boundary.

**Novel properties:**
- accessible states
- unblocked transitions
- contiguous ranges

## Examples
- The International Space Station maintains orbit through periodic reboosts to counteract atmospheric drag. *(engineering)*
- In 2003, the Northeast Blackout spread because one overloaded transmission line hit trees that hadn't been trimmed. *(institutions)*
- CRISPR-Cas9 edits DNA only when guide RNA finds a matching sequence in the genome. *(biology)*
