The formation of the moon was originally thought to be a “big collision theory”, but now it has been discovered by Japanese exploration, which adds new doubts

As the closest star to the earth, the moon has become the first step for human beings to step into the interstellar civilization, and has been the object of human beings’ research. Therefore, the mystery of the origin of the moon has gradually been discussed by people.

For more than 40 years, there have been many theories and hypotheses about the formation of the moon. Some people think that the moon was captured by the earth, some people think that the moon was formed with the earth, and some people think that the moon was thrown out from the earth. But the “big collision theory” is a hypothesis accepted by many mathematicians in the academic circle in recent years.

According to the “big collision theory”, the Earth collided with a planet named Theia, melting and mixing the two planets.

Finally, a part of the broken stars cooled and solidified, and after constant grinding of time, formed today’s moon.

Dr. Zheng Yongchun, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences, told Science and Technology Daily: “in the early days of the formation of the solar system, the major planets had just formed, the space of the solar system was still chaotic, and the orbits of some celestial bodies were not stable. It is very likely that the primitive earth would collide with Theia.”

However, after the impact, it is uncertain whether the moon will be split only after complete mixing or after partial mixing.

Dr. Zheng Yongchun also said: “although there are still some lunar observation facts that can not be fully explained by the” big collision theory “, this theory is the hypothesis that can explain the most lunar observation facts at present, and has been recognized by most scientists in the academic circle.”

However, recently, the “big collision theory” has been questioned by some scientists, and how the moon was born has become a mystery again.

This time, the question comes from Japan’s lunar exploration project.

In 2007, the Japan Aerospace Research and development agency launched the Lunar Goddess probe, and launched the exploration of lunar element abundance, mineral composition, topography, geology, gravity field, lunar and solar terrestrial plasma environment and other projects.

Finally, a lot of valuable information was sent back, including the distribution map of “carbon ions” on the lunar surface.

Originally, Japan did not pay much attention to the distribution map of “carbon ions” on the lunar surface, but recent research shows that traces of carbon and volatile water may appear in volcanic debris on the lunar surface.

These traces are likely to affect human exploration of the origin of the moon, which is very important. Therefore, Japanese scientists took out the moon goddess detection data more than ten years ago and found clues.

Originally, according to the “big collision theory”, when two planets collide, they will produce very high temperature, about 4000-6000 Kelvin. At such a high temperature, the volatile matter will vaporize and disperse completely, eventually leading to little or no volatile matter in the debris that later became the moon. Scientists vividly call it the “dry” moon.

However, Japanese scientists confirmed that there are still many carbon ions on the surface of the moon, and these carbon ions are unlikely to come from asteroid impact, and can not be explained by the deposition of solar wind. “It is estimated that the rate of carbon emission is about 5.0 × 10 ^ 4 per square centimeter per second, which is greater than that provided by possible solar wind and micrometeoroids. “

In addition, the concentration of carbon varies in different regions of the moon. On the front of the moon, the younger volcanic basalt plain area is higher than the older plateau area, which also shows that the carbon is buried below the surface of the moon and comes to the surface with the geological activities of the moon, rather than being sent to the moon from space.

So they concluded that this carbon belongs to the moon and has been with the moon for billions of years. This makes scientists have to rethink the formation of the moon.

In any case, this discovery has led us to re-examine our understanding of the moon and its formation.

According to NASA’s plan, they will return to the moon in 2024 and send astronauts to the moon to explore the planet we have been away from for 50 years.

At that time, perhaps NASA astronauts can use more advanced equipment, with more clear goals, to give us a final answer.
