Webb1 mars 2024 · State of the art calculation of Helium-4 production in the Big Bang involves following a fairly large reaction network, between the various light elements in their thermal bath of photons and neutrinos. It is a sufficiently complicated calculation that it is done numerically on computers.

Webb8 maj 2012 · This is the process that occurs during most of a star's lifetime. After the hydrogen in the star's core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point the process releases energy. Webb22 juni 2024 · Hydrogen and helium are the most abundant elements, accounting for around 98% of matter. The next two abundant elements are oxygen and carbon. In 1920, Arthur Stanley Eddington proposed that stars fuse hydrogen and make helium. He suggested the process may account for the formation of other elements.
