How Theia, the Planet that Created the Moon, Could Also Be Hiding in Earth’s Core

In this episode, we explore a new theory that suggests that the moon was born from a collision between Earth and another planet called Theia, and that this collision also left behind some traces of Theia in Earth’s core. These traces are called large low-velocity provinces (LLVPs), and they are two massive structures deep within the Earth’s mantle. We explain how this theory was tested by computer simulations, and what it means for our understanding of the Earth’s evolution and the moon’s origin.
