| thanny said: I dont think anyone is denying that fusion is an actual process... obviously fusion is fact. Its happening in stars constantly; proton-proton chain fusing and He fusing. Natural fusion reactions in stars can only, however, produce up to element 26 (Fe). and yet elements naturally occuring goes up to 92 (U). |
Supernovae produce heavy elements.
Concerning iron's role in fusion. You can fuse any elements together to create higher ones, however you can only gain energy out of fusion up to iron (element 26). Past iron, nuclear fusion consumes energy instead of gaining energy. Fusion creating elements higher than iron only means that the star lost energy producing said element, which occurs in supernova.
