Ancient Collision Unveiled: Earth's Mysterious Blobs Hold Clues

New research suggests that two massive "blobs" deep inside Earth's mantle may be "buried relics" from a collision 4.5 billion years ago between Earth and a proto-planet called Theia, which is believed to have formed the moon. These blobs, known as large low-velocity provinces (LLVPs), are hotter and denser than the surrounding rock and have been hiding near Earth's core. The collision and the remnants it left behind may have played a role in Earth's evolution and its ability to support life. While the theory is not yet proven, it provides a credible explanation for these anomalies and adds weight to the Giant Impact Hypothesis.
