noun ˌnjʊːklɪəʊˈsɪnθɪsɪsˌn(y)o͞oklēōˈsinTHəsəs

Example sentencesExamples
- Physicists call this process nucleosynthesis, and it had to occur before the structures we observed today, such as atoms and molecules, could exist.
- They more or less figured out the whole story, including predictions for primordial nucleosynthesis and the cosmic microwave background.
- Evidence from both the cosmic microwave background and primordial nucleosynthesis gives tight bounds on how much ordinary matter there is.
- Before nucleosynthesis begins, protons and neutrons are continually interconverting by means of weak nuclear interactions (the nuclear interactions are described in more detail a bit later on).
- The one problem with the story of stellar nucleosynthesis as developed in the 1950s was that it could not explain where helium came from.
