Water is life, and it seems that an ocean is hidden beneath the Earth's crust at a depth of more than 2900 km.
In a recent study on Earth's water reserves by the University of Leeds and published in Nature Geoscience, two main hypotheses are raised.
According to the study authors, it is known that there are water reserves in the depths of our planet.
But where does the water found in the mantle, which is the area between the crust and the core, come from?
According to the first hypothesis, it was asteroids that brought water to Earth during the genesis of our solar system, where the sun was born 4.6 billion years ago, and the Earth dates back 4.5 billion years.
The water brought by these celestial bodies has remained within the Earth since its formation began.
The second hypothesis is that water arrived later, hydrating a mantle that was completely dry at the beginning of time.
Thus, conditions have been created in the laboratory to study and understand more about what happens inside, and through chemical reactions, two new minerals have been discovered, capable of capturing and retaining high amounts of water.
This means that when the ancient ocean of lava that covered the Earth in the early stages of life cooled and solidified, these water-rich minerals may have formed and are still there.
Despite the enthusiasm, scientists say that the study cannot be considered complete and conclusive, but the possibility that there really is a giant ocean of water beneath us exists.
The impossibility of verification still remains, as man has so far only been able to reach 12 km deep into the planet, at a point in Russia, and beyond that, everything is theoretical and recreated in the laboratory based on knowledge and calculations.
