Moon - the result of cosmic collision


30/07/2012

Scientists have shown a new theory of the formation of the Moon. The debate over this theory are maintained for many years, been many different versions that had flaws and contradictions.

At the moment, the most acceptable is the theory of the collision, according to which, the Earth, faced with the unknown before this celestial body, the Moon formed from the ejected during the impact of substance.

But until now, unknown, or speed, or size of a celestial body in a collision.

Until that time, it was believed that the Earth was allegedly faced with the planet Mars (Theia), which moved very slowly in space.

This kind of clash sharply higher than the temperature of the two bodies, as a result, much of the substance of the body and the outer part of the Earth’s mantle particles have been thrown into orbit. In the end, forming a proto-moon.

Having made the findings, the researchers suggest that the moon is composed of a mixture of chemicals and Teyi Earth.

But on the Moon compared to Earth, found an iron deficiency. It is proved that the oxygen isotopes on the Moon and Earth are almost identical. Researchers can not come to a mutual agreement, as may be explained from a scientific point of view.

Moreover, according to data published in the journal Nature Geoscience on the results of the study samples of lunar soil brought to Earth by American "Apollo" th, titanium isotopes of the Moon and the Earth are identical.

This is evidence to support the fact that the moon - it’s part of the Earth.

Andreas Reyfer with colleagues from the space center in Bern, created a computer simulation of the proto-Earth collision with a celestial body that is moving at a very high speed, and it was larger than previously thought. In a collision, impact was at an angle, rather than in the center.

When such a collision, according to the researchers, Theia would lose much less weight, which would continue its mission in space.

From the shock produced by the tangent, the majority of particles ejected into space, would have been a terrestrial origin.

For the final version, you must conduct a more thorough analysis of lunar soil samples.
