How heavier elements formed
Web27 nov. 2024 · New evidence reveals how heavy elements were created after the Big Bang. The Big Bang theory and the question of how life on Earth began has fascinated scientists for decades, but now new research ... WebIn 1938 German-born physicist Hans Bethe proposed the first satisfactory theory of stellar energy generation based on the fusion of protons to form helium and heavier elements. He showed that once elements as heavy as carbon had been formed, a cycle of nuclear reactions could produce even heavier elements.
