A new study could show how our planet became habitable, after billions of years ago, it was a real "hell", extremely hot with a huge dome of carbon dioxide, unable to be habitable. 

Due to the few traces (especially geological) left since then, it is quite difficult to say for sure how the conditions of the past have changed in hundreds of millions of years, making the planet habitable and condensing water vapor in the oceans since then. 


But two researchers from Yale University has come up with a new theory that has a pretty good scientific basis, which can prove their theory, that a kind of "weird" type of stone from the past has absorbed much of the carbon dioxide. And because of this rock, the planet began a long process to be habitable. 

"A massive amount of atmospheric carbon had to be removed," says researcher Yoshinori Miyazaki, who now works at the California Institute of Technology. to zero a theoretical model for the very early Earth ". Indeed, right from the beginning of the Earth, there are no rocks discovered and probably not even, the oldest rock discovered so far being a little over 4 billion years ago. 


Another possibility is that carbon in the atmosphere could have dissolved in the oceans, turning into solid carbonates, which could have sunk and become part of the mantle. Researchers are analyzing this hypothesis to see if it is true or not. 

We hope that the answer will be found and that research will help us better understand how our planet has become habitable now.
