Where and how did the Moon?

New research led to revise our views on the formation of the Moon. Where and how did the Moon? The prevailing wisdom is that a planet called Teja entered our solar system and collided with the Earth by running part of the molten material into orbit. Over time, this material is combined together and formed the moon. New research geophysicist Dzhunyuna Zhang shows that this theory may be wrong. In an article published in the journal Nature Geoscience, he reports that a comparative analysis of titanium isotopes from the Moon and the Earth, showed that they are almost identical. These results are contrary to the theory of the Moon’s formation of a material with a different planet.

Scientists have found that the oxygen isotopes from the Earth’s mantle and the Moon were almost identical, but it was not enough to undermine the theory of the formation of the Moon from the collision Teyi as oxygen isotopes from the Earth could mingle with the masses of the isotopes of molten material orbiting the planet after the collision. But as in the case of the isotopes of titanium, the interchange is not so easy, then this scheme mix of isotopes is much less likely.

Most scholars agree that if the planet crashed into Earth, and as a result formed our satellite, the Moon must be of a material part of this planet. According to some estimates, the number of such material should be around forty percent. If this is the case, why are the samples of lunar soil that were brought back to Earth during the Apollo program did not contain material that other planet?

According to another hypothesis, crashed into the Earth is not a planet, but an object consisting of ice, which vanished, leaving no evidence of his involvement in the launch of a piece of the Earth’s orbit.

Others do not want to give up the theory of Tiye, even with all the new data. They state that if Tay consisted of the same material as the earth, the isotopes and should be identical. The probability of such a scenario exists, although quite small. Let us hope that the new research will give a definite answer to this question.
