Nuclear fusion is a process that occurs in stars, where two atomic nuclei slam together with enough force to overcome their mutual repulsion and form one, heavier atom. This process releases a tremendous amount of energy and is responsible for the sun's energy production. While nuclear fusion is a highly complex phenomenon, the basic idea is that lighter atoms combine to form heavier ones, releasing energy in the process.
