The video explains the process of nuclear fusion in the sun's core, where hydrogen atoms fuse under immense pressure and gravity to form helium, releasing energy. This energy production process is crucial for the sun's stability, maintaining hydrostatic equilibrium. The sun converts millions of tons of hydrogen into helium every second, with some mass converted into energy that counteracts gravitational forces.
