Earth's Mysterious Mantle: Clues of a Forgotten Collision
Mysterious blobs deep within Earth's mantle, known as large low-velocity provinces (LLVPs), may be remnants of a Mars-sized planet called Theia that collided with Earth billions of years ago, leading to the formation of the moon, according to a new study. Computer simulations suggest that during the collision, a portion of Theia's rock sank into Earth's mantle and gradually formed the LLVPs near the core. Further research and the analysis of moon rocks could provide more evidence to support this theory.
