A thing is in a space where boundaries are on all sides around it.

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

**Through:** Structure arranges boundaries in space such that they form an enclosure around a thing.

**Novel properties:**
- complete enclosure
- surrounding presence
- central position within bounds

## Examples
- The Pacific Ocean is bounded by Asia, the Americas, and Antarctica, enclosing its vast waters on all sides. *(geography)*
- Neutrons in a uranium-235 nucleus are surrounded by protons and other neutrons within the nuclear radius. *(physics)*
- The city of Paris was surrounded by German forces during the Siege of 1870, cutting off escape and supply routes. *(history)*
