Incredible Discovery: The Mysterious Giant Structures Hidden in the Depths of the Earth! Welcome to our channel dedicated to in-depth scientific exploration! In this fascinating video, we will take you on an exciting journey to discover previously unknown giant structures hidden within our planet. Located beneath Africa and the Pacific Ocean, these incredible formations surround the Earth's core and have long eluded our knowledge. But how were they discovered? And what do they reveal about the history of our world? Stay with us to find out! To unveil the mystery of these giant structures, scientists had to tackle the monumental challenge of exploring the Earth's interior. The Kola Superdeep Borehole, drilled by humans, reaches a depth of 12,263 meters, but it represents only a tiny fraction of the total thickness of the Earth's crust. Faced with this limitation, scientists had to adopt an innovative approach to reveal the hidden secrets within our planet. The key to this discovery lies in using earthquakes as a research tool. When earthquakes occur, seismic waves propagate in all directions through the Earth's mantle. By analyzing these waves and the recorded earthquakes in different regions of the world, scientists can map the Earth's internal structure using a technique called seismic tomography. This allows them to identify the materials and densities present in our planet. By studying seismic waves and their propagation velocities, scientists have made an extraordinary discovery. In the areas where these giant structures are found, seismic waves move slower compared to the surrounding regions of the Earth's mantle. This suggests that these formations possess distinct characteristics and likely a unique composition. However, despite these structures occupying between three and nine percent of the Earth's volume, we still do not have a complete understanding of their nature or their precise density. Several fascinating theories attempt to explain the origin of these giant structures. One of the main hypotheses suggests that they formed from the accumulation of subducted oceanic crust over billions of years. In the process of subduction, oceanic crust is pushed deep into the Earth by tectonic plates, and over time, these layers have accumulated to form these impressive structures in the lower mantle. However, an even more captivating theory takes us beyond our own planet. According to this hypothesis, these giant structures could be remnants of an ancient planet called Theia, which collided with Earth approximately 4.5 billion years ago. This cataclysmic impact led to the formation of the Moon but would have also left traces inside our planet. Recent studies suggest that if Theia's mantle was slightly denser than ours, it could explain the formation of these giant structures we are studying today. By continuing to explore and refine technologies for monitoring the Earth's interior, we hope to finally unveil the mystery of these giant structures. Thanks to ongoing advancements in seismic tomography and other research techniques, we will be able to reveal their exact composition and learn more about their origin and evolution throughout the history of our planet.
