How does the energy generation from fusing iron in a star's core differ from fusing lighter elements?
Answer
It consumes energy instead of releasing it
Fusing iron is an endothermic process, meaning it absorbs energy, which removes the primary source of outward pressure sustaining the star against gravity.
