What is Explosive Nucleosynthesis?
The blazing early universe was also an ideal place for nuclear fusion, the last observational pillar of the Big Bang theory. When the temperature of the universe reaches 1 billion to 10 billion K, lighter nuclei can converge into heavier ones. This process is called "bigbangnucleosynthesis". As the universe expands, the temperature will drop rapidly, so nuclear synthesis can only last for just a few minutes, and fusion can only occur between the lightest elements. Most of the helium and deuterium in the universe were formed at that time. Astronomers' measurements of the abundance of helium and deuterium in the universe are in line with the theoretical predictions of nuclear synthesis in the Big Bang. Nuclear synthesis also accurately predicted the abundance of protons and neutrons in the universe, providing further evidence for the Big Bang theory.
