Measurements of the amount of lithium in the universe combined with precision data from the cosmic microwave background are challenging our understanding both of stellar astrophysics and possibly even ...

Researchers from the Instituto de Astrofísica de Canarias (Spain) and the University of Cambridge (UK) have detected lithium (Li) in the ancient star J0023+0307, a main-sequence extremely iron-poor ...

In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis, archeonucleosynthesis, archonucleosynthesis, protonucleosynthesis and paleonucleosynthesis) ...

The Big Bang may not have 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 particles.

Last month, we reported on a small but enduring mystery in cosmology: why is there so much of one isotope of lithium around? Both 6 Li and 7 Li should have been produced when the first atoms formed ...

A team of scientists suggests that a Dark Big Bang may have occurred during the early evolution of the cosmos, according to Interesting Engineering. WASHINGTON - FEBRUARY 10: This image, showing the ...

Collisions between hydrogen and helium nuclei deep under a mountain in Italy have confirmed a mystery of cosmic proportions: why the amount of lithium-6 observed in today’s universe is so different ...

Our entire cosmic history is theoretically well-understood, but only because we understand the theory of gravitation that underlies it, and because we know the Universe's present expansion rate and ...

In the beginning, the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.—Douglas Adams, The Hitchhiker's Guide to the Galaxy Humans have many ...

The newly-measured rate of a key nuclear fusion process from the Big Bang matches the picture of the universe 380,000 years later. In a secluded laboratory buried under a mountain in Italy, physicists ...
