## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue)

**Through:** Matter persists in space across time, forming entities that endure.

**Novel properties:**
- enduring presence
- spatiotemporal continuity
- persistent identity

## Examples
- The USS Enterprise (CVN-65) remained afloat and operational for 51 years despite constant exposure to saltwater and combat conditions. *(engineering)*
- Mount Everest's rock and ice mass has persisted in the Himalayas for over 60 million years while tectonic plates continue to shift beneath it. *(geology)*
- The Bitcoin blockchain, once written, retains transaction data across thousands of nodes without degradation since its 2009 inception. *(computing)*
