In a groundbreaking revelation, researchers have proposed that remnants of an ancient planet named Theia, believed to have collided with Earth approximately 4.5 billion years ago, might still be buried within our planet.

This collision is thought to have led to the formation of the moon. The remnants of Theia are suspected to be located in two large regions of Earth's mantle, known as Large Low-Shear-Velocity Provinces (LLSVPs).

These regions are distinct from the rest of the mantle, with seismic waves moving slower through them, suggesting they are hotter and possibly denser.

The idea of connecting Theia to the LLSVPs was proposed by Qian Yuan, an Earth scientist at Arizona State University.

Yuan's calculations comparing the size of the two LLSVPs to the size of Mars' mantle, a rough estimate for Theia's size, found a near-perfect match when the moon was added.

This discovery opens up a new avenue for research, potentially reshaping our understanding of Earth's geological history and the early solar system.

Further support for this hypothesis comes from estimates of Theia's composition and density. Theia's mantle is believed to have a higher abundance of iron oxide than Earth's, making it denser.

Therefore, when the two planets collided, Theia's mantle would have sunk. If Theia was any denser than these estimates, its mantle would have formed a global layer instead of two piles. This hypothesis, while still new and uncertain, opens up a new avenue for research.

Yuan hopes that more researchers will test this hypothesis, collecting more evidence to either prove or disprove it.
