nucleosynthesis models

Nucleosynthesis models describe how the elements in the universe are formed through nuclear reactions in different cosmic environments. These models explain the processes that create atoms like hydrogen, helium, and heavier elements during events such as the Big Bang, stars’ lifetimes, and explosive phenomena like supernovae. They use physics to predict the abundance and distribution of elements over time, helping us understand the universe’s chemical evolution—from the earliest moments to the elements making up planets and life.
