Physicists are highlighting that nucleosynthesis, the primordial formation of light elements such as hydrogen and helium in the first minutes after the Big Bang, has now entered the era of precision cosmology. One of the Big Bang theory's four foundational pillars, it can increasingly be tested against measurements of the cosmic microwave background and the abundance of deuterium and helium, matching observations with remarkable accuracy.
