# photo (visual)

a mark that stays with a pattern of energy that was in a place at a time

## Emergence
**Emerges from:** [marks](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-marks.visual), [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [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)

**Through:** the mark of matter stays with the pattern of energy that occurred in a place at a time

**Novel properties:**
- enduring image
- spatiotemporal trace
- formed persistence

## Examples
- The 1977 Voyager Golden Record carries encoded images of Earth's life and culture as etched patterns in gold-plated copper, launched into interstellar space. *(space)*
- The latent image in a Kodak Tri-X 35mm film negative forms when silver halide crystals trap photons during a 1969 Apollo 11 moonwalk. *(photography)*
- A 2023 LIGO detection records gravitational wave patterns from two black holes merging 1.3 billion years ago, stored as laser interference data. *(physics)*
