Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major geological event where Earth was heated to temperatures above iron’s melting point. Would a coreless Earth even be sustainable? Could humans live on an Earth with no core? And what kind of environment would we see on this type of Earth?
