Scientists, at their latest Scientific article Published in Nature Astronomy, Analyze the Man Who Created Himself A new model for the formation of the Earth.
The prevailing theory in astrophysics and cosmology is that Earth formed from cartilaginous asteroids. These are relatively small, simple clumps of rocks and minerals that formed early in the solar system, said planetary scientist Paolo Susi of the Swiss Federal Institute of Technology in Zurich, Switzerland.
According to the research team, the current theory does not explain the exact chemical composition of Earth, which is poorer in light and volatile elements such as hydrogen and helium than expected.
While a star is made up of Dense matter in a cloud of cosmic gas and dust, the remainder begins to form a disk around it. Planets made up of smaller clumps slowly begin to form in the disk. They clash with each other and defy First electrically, then gravity. This theory is called the accretion model and is supported by observational evidence.
However, this model leaves many question marks, including why are there relatively few volatile and lighter elements in the present-day Earth? To date, this has been explained by the fact that the heat during the collision can lead to the evaporation of some elements of this type.
Scientists decided to analyze the possibility that the Earth did not consist of cartilaginous asteroids, but from planets. They are the “Planets of the Planets” and are the largest celestial bodies that have managed to form a chemically diverse core.
Scientists have done simulation They include minor planets instead of asteroids. The ground turned out to be the most likely outcome of the model implemented.
The results of the research are very important for the Earth and its composition, but also important for understanding the diverse composition of other rocky planets in space.
– Although we suspected it, we still found this result very impressive. Not only do we now have a mechanism that better explains the formation of the Earth, but we also have a reference to explain the formation of other rocky planets. Our research shows how important it is to consider dynamics and chemistry when trying to understand planet formation. I hope our findings will lead to closer collaboration between scientists in these two fields, Sosi said.
