Scientists have discovered two giant structures in the bowels of the Earth

Under Africa and the Pacific Ocean in the lowest part of the earth's mantle surrounding the Earth's core, are two giant clots. They occupy from three to nine percent of the volume of our planet.

Of course, there are no direct ways to see the Earth's core yet - the deepest pit humans have ever seen. dug, reaches a depth of only 12,263 meters, which is still very far from the breakthrough of the lower layers of the earth's crust (from 35,000 to 45 000 meters). However, scientists have already learned how to map the interior of the planet using seismic tomography, which captures energy waves during earthquakes. And this is sometimes enough for incredible discoveries.

This method revealed two large and strange structures, called large low shear regions (LLSVP). One of them was named "Tuzo" (Tuzo). In height, it reaches almost 800 kilometers, which is almost like 90 Everests.

Given that these objects are denser than their surrounding mantle, they are likely composed of a different material. But geologists have not yet been able to determine it. Seismic tomography data is not yet enough even to calculate the density.

One hypothesis is that LLSVPs are piles of oceanic crust that have accumulated over billions of years.

Another version suggests that these rocks may be the remains of the ancient planet Theia. Approximately 4.5 billion years ago, it allegedly collided with the Earth, resulting in the formation of the Moon. Now there are suggestions that some of its fragments are stuck in the earth's mantle, and did not fly away into deep space.
