Ancient Alien World Remnants Found Near Earth's Core

A new study suggests that remnants of the Mars-size rock, Theia, which collided with Earth and helped create the moon, may be buried near Earth's core. Computer simulations indicate that dense relics of Theia's mantle could have sunk and solidified in Earth's lower mantle, forming continent-size blobs that are more iron-rich than Earth's normal mantle rock. These blobs could have influenced geological activity unique to Earth, such as plate tectonics and subduction. Traces of these relics could potentially make their way to the surface through mantle plumes. The findings provide insight into Earth's geological evolution and its distinct characteristics compared to other rocky planets.
