Big Bang nucleosynthesis

After this, Bethe did work on big bang nucleosynthesis.

It was also formed in enormous quantities during Big Bang nucleosynthesis.

This is how the formation of the light elements in big bang nucleosynthesis is calculated.

Big Bang nucleosynthesis had a brief period during which it could operate, so only the very lightest elements were produced.

(see also Big Bang nucleosynthesis) which can be considered the "birth" of our Universe.

Along with making major contributions to big bang nucleosynthesis, dark matter and dark energy, he has contributed to the theory of structure formation.

Their composition matches the composition predicted from Big Bang nucleosynthesis.

Big Bang nucleosynthesis is the theory of the formation of the elements in the early Universe.

This is because hydrogen and helium were almost the only types of atoms formed in Big Bang nucleosynthesis.

Alpher's dissertation in 1948 dealt with a subject that came to be known as Big Bang nucleosynthesis.

The next step after leptogenesis is the much better understood Big Bang nucleosynthesis, during which light atomic nuclei began to form.

This first process, Big Bang nucleosynthesis, was the first type of nucleogenesis to occur in the universe.

An asymmetry in the number of leptons and antileptons is not mandatory for Big Bang nucleosynthesis.

He made additions to the big bang nucleosynthesis model that built upon the work of the classic Alpher-Bethe-Gamow paper.

Some cosmologists have proposed that Big Bang nucleosynthesis suggests there is a fourth "sterile" species of neutrino.

There are two important characteristics of Big Bang nucleosynthesis (BBN):

Big Bang nucleosynthesis produced no elements heavier than beryllium, due to a bottleneck: the absence of a stable nucleus with 8 or 5 nucleons.

Big Bang nucleosynthesis predicts a primordial abundance of about 25% helium-4 by mass, irrespective of the initial conditions of the universe.

The total amount of baryonic dark matter can be inferred from Big Bang nucleosynthesis, and observations of the cosmic microwave background.

Li is one of the primordial elements (or, more properly, primordial nuclides) produced in Big Bang nucleosynthesis.

As the Universe cools further, big bang nucleosynthesis occurs and small quantities of deuterium, helium and lithium nuclei are created.

A gluino that lived longer than this would disrupt Big Bang nucleosynthesis or would have been observed as an additional source of cosmic gamma rays.

The first nuclei were formed about three minutes after the Big Bang, through the process called Big Bang nucleosynthesis.

In this era, the Big Bang, the subsequent inflation, and Big Bang nucleosynthesis are thought to have taken place.

Since the clouds of gas have no heavy elements, they likely formed in the first few minutes after the Big Bang, during Big Bang nucleosynthesis.
