## Emergence
**Emerges from:** [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), [hot](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-hot.temperature), [big](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-big.size), [form](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-form.shape), [light](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-light.visual), [make](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-make.verb)

**Through:** hot matter in a stable large form interacts to release energy as light

**Novel properties:**
- self-sustaining energy emission
- stable high-temperature structure
- luminous spatial presence

## Examples
- The Sun fuses 600 million tons of hydrogen into helium every second, emitting light and heat. [astronomy] *(physics)*
- Betelgeuse, a red supergiant in Orion, radiates visible and infrared light due to its high temperature and large size. [astronomy] *(astronomy)*
- Proxima Centauri, a small but hot star, emits light detectable from Earth despite being 4.24 light-years away. [astronomy] *(astronomy)*
