Nearly all stocks of nitrogen, water, organic matter and other "lifestyle bricks" were brought to Earth by asteroids and comets, as it is previously thought, and by the "great-grandmothers" of the month, Tay, according to US scientists in an article published in Science Advances. [19659002] According to geologists, no other version can explain the quantity of these substances and their life span on Earth.
"The isotopic composition of rocks, sulfur, carbon and nitrogen particles and their total amount in the crust and mantle suggests that they had to travel to Earth at a time when the back grandmother Mi met Damanvir Greval of Rice University in Houston
The planets of the solar system formed inside the gas nebula and were the origin of hot spheres.
Scientists have been arguing for years about the origin of the Earth, organic compounds and other substances that have created life
The theory that, 3.8 billion years ago, they "brought" on our planet asteroids, has been questioned because of the different ratio of carbon and nitrogen in rocks of the earth and asteroid chondritas., formed simultaneously with the Sun
Thus , on Earth, the carbon is about two is more important than in the asteroid debris
In addition, geologists have discovered a large amount of sulfur in the heart of the earth.
Grevy and his colleagues claimed experiments and came to the conclusion that to bring sulfur could only one object – Tey, a protoplanet the size of Mars. It collided with Earth about 4.5 billion years ago. As a result, its core, rich in sulfur, is "dissolved" in the heart of the Earth and the wreckage thrown into space has become the Moon.
This same collision has most likely brought to Earth almost all supplies of water, organic matter and other substances necessary for birth.
