iron to gold process

Sep 22, 2019 This process is called nucleosynthesis. Elements heavier than iron are formed in the stellar explosion of a supernova. In a supernova, gold may be transformed into lead—but not the other way around. While it may never be commonplace to transmute lead into gold, it
