New theory of Moon formation

Have you ever looked at the Moon and wondered where the " magnificent sphere" came from? A recent study by scientists has suggested the theory that the Moon formed from debris left from a collision between the young Earth and a solid object the size of Mars. .

According to that theory, this collision also created patches of night light in the universe.

According to Space.com, the results of soil analysis on the Moon and on Earth have partly shown the correctness of the hypothesis: Earth has been hit by a large planet of Mars, thus forming the Moon. .

This hypothesis is named the Giant Impact Hypothesis, proposed in the 1970s, but so far no one has been able to find the mysterious object named Theia - colliding with the Earth. how is that

According to this theory, more than 60% of the Moon's material comes from Theia's body, about half of it comes from Earth. That is consistent with research that shows that the Moon contains matter in the celestial body that once collided with the Earth.

Previous studies have shown that the ratios of isotopes such as oxygen, titanium, silicon . in all the solar system planets are different, but on the Moon and Earth, those ratios are the very same.

This contrasts with the theoretical model of the Big Collision Hypothesis - this argument suggests that the Moon is primarily composed of Theia's planetary matter, so its composition is expected to be different from Earth. .

The main author of the study, astronomer Allesandra Mastrobuono-Battisi of the Israeli University, Haifa said: " According to the analysis results, Earth and Moon are actually twins. Differences between compounds in the soil layer is very small and also very difficult to detect, but they really exist.

That means, we can now fairly affirm that there has been a major collision between Theia and Earth and we have a general understanding of Theia's geological - chemical situation. ".

Experts from Space said that each planet is made of materials that can be distinguished from each other . However, this coincidence is quite interesting because by studying most of the Moon samples, experts estimate it contains about 70-90% of Theia's matter. Experts are still working on it to be able to give the most definitive solution to the formation of the Moon.
