WebApr 5, 2024 · The fusion that occurs in the core of the Sun occurs in nothing like the conditions you might be thinking of in a bomb, or a fusion reactor. In particular, it occurs at much lower temperatures and at a much lower rate. A cubic metre of material in the solar core is only releasing around 250 W of power by fusion. WebNov 3, 2024 · The fusion of elements continues until iron is formed by silicon fusion. Elements lighter than iron can be fused because when two of these elements combine, they produce a nucleus with a mass lower than the sum of their masses. The missing mass is released as energy. Therefore, the fusion of elements lighter than iron releases energy. …
