A Collision With Another Planet Could Have Allowed for Life on Earth

The world you are Today Walk on is not the same planet that was born 4.5 billion years ago. Many scientists believe that in its childhood the world collided with another world GoodnessAnd instead of destroying it, it was converted, incorporated the mass of the foreign body into our known planet. Recent research has added another level of relevance to that estimated cosmic event: scientists believe that the primary situation of life on earth without any other body can never be present.

A group of Bern University in Switzerland argues that due to the close proximity of the sun, the proto-affair that existed before this potential conflict lost the unstable elements needed to form complex molecules. Any hydrogen, carbon or sulfur, their analysis suggests that the proto-prophet form evaporate for the first 3 million years. And so if the earth was developed without external inputs, they say, it will probably be a dry world, more hostile to the development of complex life.

On the other hand, if a body is formed on the outskirts of the solar system-a region that produces a large amount of water and other unstable ingredients-and it hits a rocky planet like proto-afford, it features our planet today, even after the Earth’s initial aggression process, it can identify our planet. This hypothesis is in line with other proposals that point to the exterior source of the water, according to which the ice meteorite bombed the primitive earth and deposited their molecules.

Published in a study The progress of scienceResearchers properly measured the radioactive erosion of Chromium -1 to Manganese -53, both in the earthly sample and meteorite pieces on earth. Since these space rocks were formed at the same time as the planets of the sun and the solar system, their marks analyzed and their composition is equivalent to opening a time capsule from the past. By calculating the radioactive erosion of the manganese -53, the researchers revealed the time when the planets stop exchanging material with their environment and they fixed the chemical elements that would keep them forever.

Their results show that the Proto-Earth seals its ingredients just 3 million years after the birth of the solar system. Furthermore, they found that the proportion of the primary planet in the manganese with chromium was very low, suggesting that the proto-afford is a very heated world, capable of expelling manganese. Since this ingredient is less unstable than more important ingredients like hydrogen, carbon or sulfur, they must have escaped.

“Thanks for our results, we know that the Proto-meaning was initially a dry rocky planet. So it can be assumed that it was only a collision with Theia that brought unstable material to the earth and eventually made life there,” said at the University of Bern University, said at the University of Burn, at the University of Burn.

Thia is the name of the estimate that has hit proto-afford about 4.5 billion years ago. Researchers believe that the impact was 30 to 100 million years after the beginning of the solar system – it is, a few million years after our ancestor on our planet became a very dry world.

However, the arrival of water and other unstable elements is not equal to the immediate rise of life. The alone does not produce life, but it creates much more favorable chemicals and physical environment for other molecules to appear and biological processes with them enhance the cells. In this sense, Thia set the stage but the spark did not burn.
