# cross (pass)

To go through a boundary from one place to another.

- Computed level: L4 (depth in the emergence graph, not abstraction)
- Status: published  ·  Domain: systems

## Emergence
**Emerges from:** [go](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-go.movement), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement)

**Through:** Motion carries a thing up to a boundary and on through it, so that what was inside is now outside; the crossing is the moment the boundary stops holding the thing.

**Novel properties:**
- an event located at a boundary
- before and after that differ in kind
- the moment a wall is tested
