How does Earth have a companion after a cosmic catastrophe?



After the cosmic collision that led to the emergence of a group of debris, chemical elements emerged on our planet that are critical to the emergence of life. This conclusion is made by American scientists.

The impact occurred about 4.4 billion years ago. The earth has been hit by "a Mars-sized wandering planet," killing debris in space. From these debris, our natural moon is formed later. This is reported by The Guardian.

Scientists are convinced that, in addition to creating a new celestial body, the cosmic incident has another consequence. In particular, carbon and nitrogen from a wandering planet, now incorporated into organic compounds, hit the Earth. Petroleum scientists from Rice University of Texas came to this conclusion after a series of experiments with geochemical reactions at high temperatures and pressures in the depths of our planet.

They wanted to understand how the Earth received key chemical elements: from meteorites or possibly from some other ancient sources. Team Leader Démanvir Greval has discovered that the planet with a sulfur-rich core should have large reserves of carbon and nitrogen on the surface.

Most likely, the core of the Earth is composed of iron and nickel. Therefore, an outer planet with a sulfur core can transfer these volatile elements to the Earth in the required proportion if it crashes into it. For such conclusions, the researchers came through computer simulation of multiple scenarios for the development of the Solar System, comparing the results with what it actually has.

"Investigating primitive meteorites, scientists have long discovered that Earth and other solid planets in the inner circle of the Solar System are devoid of volatile substances. "The scenario we propose is the first to explain the time span and the method of obtaining these substances based on geochemical evidence," he added.

As reported by Country, Japan will for the first time in history release artificial meteorites over the Earth. Compared with natural, Japanese meteors are more massive and will move more slowly in the atmosphere, allowing them to be observed longer than usual.

Note that during the eclipse the meteorite fell to the moon and formed a new crater.
