…Eddington and expanded on by George Gamow and then Hans Bethe that the energy released from nuclear fusion reactions accounted for the longevity of the Sun as a source of heat and light. In 1920, Arthur Eddington, on the basis of the precise measurements of atomic masses by F.W. Aston and a preliminary…
