A high-mаss stаr neаr the end оf its life undergоes successive cycles оf energy generation in its core in which gravitational collapse increases the temperature to the point where a new nuclear fusion cycle generates sufficient energy to stop the collapse. This process does not work beyond the silicon-fusion cycle that produces iron. Explain.
