Elements of the past: Big Bang Nucleosynthesis and observation
The theory of nucleosynthesis during the first few minutes after the big bang makes very clear predictions about the abundances of light atomic nuclei in the early universe - about the contributions of hydrogen (single protons), deuterium, helium-3, helium-4, ...
Equilibrium and Change: The physics behind Big Bang Nucleosynthesis
Studies of Big Bang Nucleosynthesis - the formation of atomic nuclei like those of helium, deuterium or lithium in the early universe - have led to some of the most impressive predictions of the big bang models. A brief overview can be found in the spotlight ...
Big Bang Nucleosynthesis: Cooking up the first light elements
The big bang models - the cosmological models based on general relativity - tell us that the early universe was extremely hot and dense. At the earliest stages that can be modelled using current physical theories, the universe was filled with radiation and ...
