Which heavy elements are primarily forged inside the core of massive stars?
Answer
Oxygen, carbon, iron, and calcium
While the early universe consisted mostly of hydrogen and helium, the complex chemistry required for planets and life did not exist until stars processed these simpler atoms. Massive stars act as cosmic foundries, using the extreme pressure and temperatures within their cores to fuse elements. Elements such as oxygen, carbon, iron, and calcium are created through stellar nucleosynthesis and are subsequently dispersed into the cosmos during the star's death.
