The video explains the sun's energy source, starting with its formation from gas and dust. It describes nuclear fusion, where protons fuse to form helium, releasing energy. The sun's stability is maintained by a balance between gravitational and outward pressure. Additionally, magnetism adds complexity to the sun's behavior.
