# cross (symbol)

a shape made by two lines that touch together

- Computed level: L13 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: cross  ·  Arena: cross

## Emergence
**Emerges from:** [line](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-line.geometric), [touch](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-touch.together)

**Through:** the lines touch together

**Novel properties:**
- intersection point
- cross shape

## Examples
- The Christian cross in St. Peter's Basilica, constructed in the 16th century, remains a central architectural feature in Vatican City. *(institutions)*
- A plus sign (+) etched in silicon at Intel's Fab 34 in Ireland marks alignment points during microchip lithography. *(engineering)*
- Two laser beams intersecting at 90 degrees in a LIGO detector create an optical cross to measure gravitational waves. *(physics)*
