How the Sun works - Fusion and Quantum Tunneling

The video explains why the Sun has lasted for 4.5 billion years, fueled by nuclear fusion. Unlike Earth, where extreme heat is needed for fusion, the Sun uses quantum tunneling to fuse hydrogen atoms into helium, releasing energy. This process allows the Sun to convert its mass into energy, sustaining it for billions of years. Quantum mechanics plays a crucial role in this energy production.
