☆ Did the same collision that formed the moon create mysterious blobs inside Earth?

The theory, called the giant-impact hypothesis, explains many fundamental features of the moon and Earth. And many scientists assumed any debris Theia left behind on Earth was blended in the fiery cauldron of our planet’s interior. They were already aware that there are two massive, distinct blobs that are embedded deep within the Earth. That’s when he learned new details about Theia, the mysterious projectile that presumably struck Earth billions of years ago. And, as a trained geophysicist, he knew of those mysterious blobs hidden in Earth’s mantle.

By Will DunhamWASHINGTON (Reuters) - Seismologists have recognized since the 1970s that two mysterious continent-sized blobs reside in the deepest part of Earth's mantle, one under Africa and the other under the South Pacific region. Based on these simulations, they proposed that most of Theia was absorbed into Earth, forming the blobs, while residual debris formed the moon. If the study's conclusions are correct, these blobs would represent the first direct evidence of the hypothesized moon-forming collision. "It is incredible because we can uncover relics of another planet - Theia - if we dig deep enough in Earth's mantle," added planetary scientist and study co-author Hongping Deng of the Chinese Academy of Sciences' Shanghai Astronomical Observatory. Asimow said that if their conclusions are correct some volcanic rocks that reach Earth's surface may provide samples of a vanished planet.
