Episode notes
Stars' Internal Chain Reactions
- Stars undergo internal chain reactions due to fusion.
- Fusion creates heat, increasing fusion probability, creating a self-sustaining loop.
Stellar Explosions
- Stars explode when fusion's outward push can no longer counter gravity's inward pull.
- This imbalance can lead to a core collapse supernova or a Type 1a supernova.
Supernova Types and White Dwarves
- Not all stars go supernova; some, like our Sun, will become white dwarves.
- White dwarves can explode into a Type 1a supernova under specific conditions, such as acquiring material from a nearby star.
