A new study by

America "science" magazine published 6 days to say, 40 years Cheap Michael Jordan NCAA Jerseys ago, "Appollo" spacecraft from the moon rocks further confirmed this hypothesis: the moon is the formation of planets and the Earth collided with a Mars size after.

for decades, scientists have not completely sure Cheap North Carolina Basketball Jerseys how the Cheap Michigan Wolverines Basketball Jerseys moon formed, but they made a giant impact hypothesis most people recognized, namely 4500000000 years ago, a Mars size, called "Theia" planet earth, earth and self repair, and "a lot of Theia" aggregation in earth orbit to form the moon.

Researchers from the University of Gottingen in Germany

institutions such as the report says, the inner solar system planets by the unique isotopic composition, isotope ratio Cheap Marquette Golden Eagles Jerseys so that the best method of giant impact hypothesis that the earth and the moon, titanium and silicon elements such as oxygen, but only after the conclusion of the study are quite similar to the moon rock and the earth rock, unable to confirm the main source to an extinct objects.

latest study using an advanced analysis technology is very sensitive, analyses provided by NASA, the last century sixty or seventy's "Appollo" lunar spacecraft. The results showed, lunar oxygen 17 and oxygen isotope ratio is 16, the rock and the earth are different. The lead author of the study, Daniel · of the University of Gottingen; 赫瓦茨 said in a statement: "the difference is very small, hard to detect, but there. We now have reason to believe that the collision Cheap Chris Paul NCAA Jerseys happened."

is currently the most about the origin of the model estimation, the moon 70% to 90% ingredients from "Theia", the remaining 10% to 30% from the early earth. Hector watts thinks, the component may be half from "Theia, half from the earth". But he also said the idea is to get more evidence that.

when the sun shines, the other planets in the solar system began to form. But millions of years the earth's moon was gradually begin to form, there are three kinds of lunar theory to explain is how to generate: giant impact hypothesis, together form the theory and capture theory.

giant impact hypothesis

explains the origin of the moon, "collision" hypothesis is undoubtedly the most mature hypothesis. Whether in the dynamics and chemistry of the universe, giant impact hypothesis can explain the problem better than any other hypothesis. The hypothesis that 4500000000 years ago, one called "Theia", the size of Mars similar proto planetary relatively moderate hit the earth, the impact is the result of Theia iron core into the core of young earth, the mantle and the earth's mantle captured, however, there are a large part of Theia and the mantle of the earth because of the collision and thrown into orbit around the earth, these substances quickly merge, eventually formed the moon.

together form the theory

the moon may also be formed simultaneously with the earth. The theory is that >
