They are among the largest and strangest of the structures on Earth: large, mysterious blobs of thick rock lying deep within the lower parts of the planet ‘s mantle.
Two of these large masses – known as high-shearing continents (LLSVP) – have one buried beneath Africa, the other beneath the Pacific Ocean.
These anomalies are so great, they themselves breed their own temptations, like the great wonder that is currently growing inside and weakening the Earth’s magnetic field, called Atlantic Anarchy.
As to how and why the LLSVPs became like this within the costume, scientists have many opinions, but little hard evidence.
What is known, however, is that these large blobs have been around for a long time, with many thinking that they may have been part of the Earth since then before the great impact it caused. ‘Moon – old scenes of the catastrophe between Earth and Theia’s supposed planet.

According to that widespread argument, Theia hit the size of Mars on Earth early around 4.5 billion years ago, with a large mass of Theia and / or possibly the Earth breaking off, and growing like the Moon known to us today in orbit around the Earth.
As for what happened to the rest of Theia, he’s not sure. Was it destroyed, or was it just recycling into eternity a place? We don’t know.
Some researchers have suggested that the hearts of these two primordial planets may have been connected into one, and that it was chemical exchanges that came with this great union that enabled life itself to prosper on earth. -world that came as a result.
Now, scientists have returned to these memorable questions with a new suggestion, and it is an idea to solve the LLSVP secret blobs as well, weaving them into the Earth / Hybrid concept. Theia.
According to a new model by researchers from Arizona State University (ASU), the LLSVPs may represent ancient fragments of Theia’s thick iron mantle, which sank deep into the Earth’s own mantle when the two developing worlds came together, and were buried there for billions of years.
“The Giant Impact hypothesis is one of the most studied models for the creation of the Moon, but direct evidence shows that the Theia influencer is still accessible,” the researchers said. , led by first author Qian Yuan, a PhD candidate studying the dynamics of clothing at ASU, explain in a summary of their findings presented last week at the Lunar and Planetary Science Conference .
“We show that Theia mantle could be several percent deeper than the mantle on Earth, which allows Theia mantle materials to sink to the lowest mantle on Earth and accumulate. into thermochemical rings that may cause the seismically observed LLSVPs. “
While there has been speculation in recent years that the LLSVPs may be alien memorabilia applied by Theia, the new research seems to be the most complete formulation yet. The findings are currently being reviewed, before being published in the future Geophysical Research Letters.
Beyond the modeling of fitness, the results are also consistent with previous research suggesting that some chemical signatures associated with the LLSVPs are at least as predominant as Theia’s influence.
“So the products may be primitive [originate] from the LLSVPs, which is well defined if the LLSVPs retain Theia clothing materials that are older than the Giant Influence, “Yuan and his co – authors write.
We need to see how the rest of the scientific community reacts to the team ‘s decisions, but for now at least we have another guide on exactly what these mysterious anomalies might be – and literally is the farthest explanation yet.
“This subtle idea is at least possible,” Yuan said Science.
The findings were presented at the 52nd Lunar and Planetary Science Conference, which was held as a landmark event last week.
