Stellar nucleosynthesis is the collective term for the nuclear reactions taking place in stars to build the nuclei of the heavier elements. The processes involved began to be understood early in ...

The famed Alpher-Bethe-Gamow paper of 1948, which detailed some of the finer points of Big Bang Nucleosynthesis. The light elements were predicted correctly; the heavy elements were not.

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 ...

Researchers at Beihang University and the Institute of Modern Physics have developed a unique technique for increasing the ...

Scientists have proposed the features of rapid neutron capture process (r-process) nucleosynthesis in a novel scenario, common envelope jet supernovae (CEJSNe). This study sheds new light on the ...

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter ...

An international team of researchers, led by scientists from GSI/FAIR in Darmstadt, Germany, has studied r-process nucleosynthesis in measurements conducted at the Canadian research center TRIUMF ...

Big Bang nucleosynthesis also enabled physicists to predict the number of different types of neutrinos, which helped drive cosmic expansion. But for almost a decade now, uncertainty about deuterium’s ...

An artist’s rendition of big bang nucleosynthesis, the early universe period in which protons "p" and neutrons "n" combine to form light elements. The presence of dark matter "χ" changes how ...

Dark matter continues to elude detection, and scientists are looking at alternate theories to explain its absence. One theory is that dark matter resides in a “dark mirror” universe that ...
