Nuclear Fusion and Solar Energy

The video explains the process of nuclear fusion in the sun's core, where hydrogen atoms combine under immense heat and pressure to form helium, releasing energy. This energy powers the sun and is explained using Einstein's equation, highlighting the mass loss during the reaction. The video concludes by emphasizing the simplicity and significance of this process.
