How is Gold Formed and Where Does it Come From? – APMEX
Eventually, the hydrogen in the star's core runs out, and gravity causes the star to collapse. What happens next depends on the star's mass, but gold is formed when the collapse creates a massive shockwave. During the explosion, a tremendous amount of energy creates heavy elements through the rapid neutron-capture process.
