The Power of Fusion: Unraveling the Sun's Nuclear Secrets

The video explains the Sun's core, where nuclear fusion occurs, converting hydrogen into helium. This process is challenging due to the repulsion between protons, requiring immense energy and velocity. Gravity plays a crucial role by providing the necessary pressure and heat. The Sun's mass enables this gravitational force, leading to frequent atomic collisions and energy release. Every second, a significant amount of mass is converted into energy, illustrating the Sun's power.
