Why is the center of the earth molten iron and not heavier metals, such as gold?

Question

I would assume heavier molten metals would be in the center of the earth. Is it possible that the center has different molten metals on top of each other with a high concentration of iron on the outside of the core?

Answer 1

Most of you seem to be forgetting that, initially, the Earth’s core was very wrinkled. It needed ironing. Ironing takes energy and time. Once ironed into a smooth core, the earth was better prepared to go out into the universe.
