In this video, we explore the origins of the first atom, tracing back to the big bang, where immense energy condensed to form atoms. Key concepts include: - The uncertainty surrounding events before ...

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 ...

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest ...

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

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 ...

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 particles.

In science, you don't have to get everything right in order to get the most incredible things correct. Sometimes good ideas emerge from a failed paradigm. An excellent example of both is the ...

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.

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 ...

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 ...
