Detailed explanation-1: -Nucleosynthesis 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.

Detailed explanation-2: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.

Detailed explanation-3: -Nuclear fusion reactions first occurred during the early stages of the hot Big Bang, and then didn’t happen again for tens-to-hundreds of millions of years: when the first stars formed. Despite the fact that fusion occurred at both the Big Bang and in stars, they’re extremely different from one another.

Detailed explanation-4: -Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.

Detailed explanation-5: -Nucleosynthesis in the Early Universe The term nucleosynthesis refers to the formation of heavier elements, atomic nuclei with many protons and neutrons, from the fusion of lighter elements. The Big Bang theory predicts that the early universe was a very hot place.
