Following Big Bang nucleosynthesis, local concentrations of gas collapsed to form the first galaxies and the nebulae and stars that comprise them.Gravity binds these immense structures together, and it is the gravitational collapse when stars form that creates the pressures needed to initiate thermonuclear fusion reactions, which convert four 1 H nuclei to one 4 He nucleus and release energy.
Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. In the BBN (big bang nucleosynthesis) some light elements were formed.
In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis) is the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, 1 H, having a single proton as a nucleus) during the early phases of the Universe.Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 . the big bang nucleosynthesis refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, 1H, having a single proton as a nucleus) during the early phases of the Universe.

As we will see, it begins at temperature of about 1MeV and lasts until the temperature drops to a few dozen keV. It also predicts about 0.01% deuterium, and even smaller quantities of lithium. The following stages occur during the first few minutes of the Universe: Less than 1 second after the Big Bang, the reactions shown at right maintain the neutron:proton ratio in thermal equilibrium.
Without major changes to the Big Bang theory itself, BBN will result in mass abundances of about 75% of hydrogen-1, about 25% helium-4, about 0.01% of deuterium and helium-3, trace amounts (on the order of 1010) of lithium, and negligible heavier elements. Explanation: Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4 (), helium-3 which accounts for most of the world's helium, other . Big Bang Nucleosynthesis. 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.

Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to . In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis) is the production of nuclei other than those of the lightest isotope of hydrogen ( hydrogen-1, 1 H, having a single proton as a nucleus) during the early phases of the Universe.

The theory of nucleosynthesis during the first few minutes after the big bang makes very clear predictions about the abundances of light atomic nuclei in the early universe - about the contributions of hydrogen (single protons), deuterium, helium-3, helium-4, lithium-7 to the total mass of ordinary matter contained within a given region. Answer: Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei.

This is because our data to this point only goes back to the moment of creation of the CMBR. .
Answer (1 of 6): In its "earliest"* moments, there were no elements in the universe, only pure energy.
According to big bang theory, there were series of events carried on that lead to the formation of stars in the universe. The neutrons started decaying rapidly, and determined the "initial ratio" of H (hidrogen) and He (helium) . .

Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. This is consistent with the standard or "big bang" model.The process of forming the hydrogen and helium and other trace constituents is often called "big bang nucleosynthesis".Schramm's figures for relative abundances indicate that helium is about 25% by mass and hydrogen about 73% with . Now, the other nuclei formed are usually the elements deuterium, helium and lithium or their corresponding isotopes.
