WebNucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. After about 20 minutes, the universe had expanded and cooled to a … WebBeyond this, nuclear fusion becomes endothermic, and can no longer fuel stellar burning. Various ingenious processes have been developed to produce heavier elements in the laboratory (the heaviest nucleus to date – oganesson-294 – was produced by colliding calcium-48 ions with californium-249 atoms) but just three paths to heavier nuclei ...
