Chapter 1: The Discovery of Theia

Recent research suggests that an ancient planet, known as Theia, may still reside within the Earth. This study, conducted by a team from Arizona State University, posits that billions of years ago, Theia collided with our planet, ultimately becoming part of it.

According to scientists, "In the early days of our solar system, Theia, resembling Mars in structure, likely struck Earth, leading to the formation of the Moon." Within Earth, a significant number of mysterious rocks, termed Low Shear Velocity Provinces, are believed to be remnants of this ancient planet.

Section 1.1: The Geological Significance

These Low Shear Velocity Provinces are thought to be located beneath regions like Africa and the Pacific Ocean. Their massive size is associated with the ongoing weakening of Earth's magnetic field. Research author Qian Yuan noted that these inner rocks are denser than typical geological formations.

Chapter 2: The Mantle and Its Mysteries

The mantle, which extends approximately 1,800 miles deep, constitutes about 84% of Earth's total volume. The Great Impact Theory supports the idea that this event led to the Moon's formation.

The first video provides a visual representation of the significant impact event that merged Earth and Theia, ultimately forming the Moon.

Despite extensive research, concrete evidence of Theia remains elusive. Some scientists theorize that material from Theia may have emerged from Earth's magma and transformed into crystal formations. This event is believed to have occurred between 20 and 100 million years ago. Yuan suggests that remnants of Theia's impactor could potentially be discovered, particularly components rich in iron that collided with Earth's mantle.

The second video explores the implications of finding Theia's remains within Earth, offering insights into our planet's geological history and evolution.
