He had already developed the idea of nucleosynthesis as a key .Synthesis of the Elements in Stars.

Nucleosynthesis: The Formation of Elements in the …

Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter.

The Big Bang Nucleosynthesis theory predicts that roughly 25% of the mass ofthe Universe consists of Helium.

The process is called nucleosynthesis.Nucleosynthesis requires a high-speed collision, which can only be achieved with very high temperature.

In four stars, these heavy elements appear to have originatedin some form of r-process nucleosynthesis.

Abstract: We review how our current understanding of the light element synthesis during the Big Bang Nucleosynthesis era may help shed light on the identity.

nucleosynthesis and the big bang - Universo Online

The chemical reaction by which atomic (of any chemical element) are created. Nucleosynthesis took place when the was very young. Today it takes place, for instance, in the stars' cores: the hydrogen, the most abundant component of a star, is converted into helium (this is referred to as helium nucleosynthesis) a process by which a huge amount of energy is released. This is the energy that allows the star to keep shining. When the hydrogen is used up then the star begins to transform the helium into other elements, and so on. The elements are hence used as fuel for the star, and the kind of element used in each stage of the star's life is an indication of how long it has been shining. Therefore, the chemical components of a star can provide a lot of information about its history. See also .

Burbidge, Burbidge, Fowler and Hoyle worked out the nucleosynthesis processes that go on in stars, Other Big Bang Nucleosynthesis pages: LBL, Martin White.

Big Bang Nucleosynthesis - HyperPhysics Concepts

As space expanded, temperatures dropped below those required to sustain fusion, and as a result nucleosynthesis only lasted for about three minutes. A third of the atomic hydrogen was converted into helium and no elements heavier than lithium could synthesize.

From fusing these elements, energy is released causing massive amounts of heat and light.
