scientists claim - the world of Alien has been found.

New Delhi: There are some rocks inside the earth that indicate the existence of the ancient planet Theia. It has been claimed in a study that this planet, which collided with the Earth billions of years ago, has now become part of the Earth. It is believed that in the early days of the solar system, Mars-shaped 'Thia' planet collided with the Earth, which formed the moon. Many unknown, huge rocks are still found inside the earth today called Low-Shear-Velocity Provinces (LLSVP). The Arizona State University team believes that they may be part of the same ancient world.

Different from other rocks

Of these, one LLSVP is under Africa and one is under the Pacific Ocean. Both are so vast that they are believed to be associated with the weakening of the Earth's magnetic field. The author of this research, Qian Yuan, says that these rocks are more dense than other surrounding rocks and their chemical texture is also different. Yuan says that Theia's mantle was deeper than the earth. So when the two collided, a part of it settled in the earth forever.

No proof of thia

Actually, this mantle is a thick interior of the earth that is mostly solid and stretches over 1800 miles. It falls between the core and the crust. This accounts for 84% of the Earth's volume. And the biggest thing is that the 'Great Impact' theory is quite similar to the system of moon and earth. However, no evidence of thia has been found so far. It is estimated that this incident happened 2–10 million years ago. Some proponents of this theory believe that the cores of the two planets merged and that such a chemical would have been formed that would have made life on Earth possible.

More dense than the earth

LLSVPs are related to the collision, according to a recent theory by Arizona State PhD student Yuan. Till now many attempts have been made to authenticate these rocks. Some researchers say that they originated from the Earth's magma and turned into crystals. Yuan says that the iron-filled parts of Thea merged into the mantle of the earth when the two collided. Such rocks can be found from a thia-shaped impactor. In addition, earlier research has found that chemical signatures coming from LLSVP can be dated to the time of Thia Impact. In this case, both can be combined.
