The lithium problem poses challenges to BBN models, sparking research into cosmic processes and enhancing our grasp of ...

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.

When theoretical physicists like myself say that we're studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan's Subaru telescope has revealed ...

The absorption lines at a variety of redshifts show that the fundamental physics and sizes of atoms have not changed throughout the Universe, even as the light has redshifted due to its expansion. 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 ...

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 ...

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 ...

In a secluded laboratory buried under a mountain in Italy, physicists have re-created a nuclear reaction that happened between two and three minutes after the Big Bang. Their measurement of the ...
