In a groundbreaking new study, scientists have made a remarkable discovery that sheds light on the history of our planet. Deep beneath the Earth’s surface, close to the core, lies evidence of an ancient planet that collided with Earth billions of years ago. The remnants of this planet, known as Theia, have long been a subject of fascination and debate within the scientific community.
The intriguing findings, published in the prestigious journal Nature, provide compelling evidence that two large anomalies, called “large low-velocity provinces” (LLVPs), are in fact the remains of Theia. These LLVPs, roughly the size of entire continents and twice as large as the moon, reside beneath Africa and the Pacific Ocean.
Previously, seismic waves passing through these structures had indicated a slower rate due to their high iron content. However, until now, their true nature and origin remained a mystery. The recent study finally sheds light on this enigma, proposing that Theia’s mantle material (TMM) was absorbed into Earth during the collision and subsequently formed the LLVPs we observe today.
By conducting extensive simulations of the giant impact between Theia and the early Earth, researchers demonstrated that a portion of Theia’s mantle could have been integrated into Earth’s solid lower mantle, giving rise to the LLVPs.
These findings have significant implications for our understanding of the formation of the Moon and the early history of our planet. They provide crucial insights into the dynamic nature of our solar system and how celestial bodies have influenced Earth’s evolution.
As scientists continue to delve into the depths of our planet, uncovering its hidden secrets, we are reminded of the remarkable complexity and interconnectedness of the universe. The discovery of ancient remnants from a collided planet within Earth’s core not only deepens our knowledge but also ignites our curiosity about the mysteries that lie hidden beneath our feet.
