A trip to the second dimension

"Group 1 is ready!"

"Group 2 is ready!"

"Group 3 is ready!"

"Start detecting!"

Various reports came from the scientists brought by Miss Li. Hope was still a little confused and couldn't figure out what was going on.

In this regard, Tony, who had already learned a rough idea during this period, explained to Hope.

"There are currently four mainstream hypotheses for the formation of the moon. They are the split theory, the capture theory, the homology theory and the collision theory."

"The split theory is the earliest hypothesis to explain the origin of the moon. As early as 1898, George Darwin, the son of the famous biologist Darwin, pointed out in the article "Tides and Similar Effects in the Solar System" that the moon was originally Later, due to the rapid rotation of the earth, part of the earth's material was thrown out. This material broke away from the earth and formed the moon, and the large crater left on the earth is the Pacific Ocean."

"But this view was quickly opposed by some people. They believed that with the rotation speed of the earth, it is impossible to throw something as big as that. Besides, if the moon was thrown out by the earth, then both The material composition should be consistent.”

"However, through laboratory analysis of the rock samples brought back from the moon by the Apollo 12 spacecraft, it was found that the two are very different. The age of the rocks on the moon's surface is extremely old, and the age of the rocks on the entire moon's surface ranges from 30 to 42 years old. Within billions of years, the age of the oldest rocks on the earth's surface is limited to 3.8 billion-year-old metamorphic rocks exposed in individual areas, while the age of the Pacific ocean floor rocks is extremely young, completely contrary to the 'splitting theory' theory."

Hope listened obediently and nodded silently. Tony's words were very simple, even he could understand them, although there were some things he didn't know.

"The theory of homology, this hypothesis holds that the Earth and the Moon are both diffuse nebula materials in the solar system, rotating and accreting in almost the same solar nebula area, and forming celestial bodies of different sizes at the same time. During the accretion process, the Earth A little faster than the moon corresponds to being an older brother.”

"But again, this hypothesis has also been challenged by objective facts. Still through laboratory analysis of rock samples brought back from the moon by the Apollo spacecraft, the average chemical composition of the earth and the moon is very different. People found that the moon's The rocks are also much older than Earth's rocks, so that hypothesis doesn't hold up either."

"The collision theory, to put it simply if you can understand it, is that a star about the same size as Mars collides with the earth. The fragments produced by this collision begin to revolve around the earth. In the process, these fragments begin to Condensation finally formed the current moon. But there are also many unreasonable aspects in this statement. "

When Tony said this, he hoped to learn to answer quickly and raised his hand directly and said: "You skipped the capture and said you didn't mention it. Does that mean that the moon was actually captured by the earth?"

Tony shook his head and said with a smile: "The theory of capture is to assume that the moon accidentally passed by the earth and was captured by the earth's gravity. However, many people have also suggested that for a star as big as the moon, the earth's gravity should not be able to capture it. . Therefore, some people say that the earth continues to accretion materials that enter its orbit, and over time, more and more things are accreted, and eventually the moon is formed. "

"This is wrong, and that is wrong, so what's going on?"

I hope I don’t want to beat around the bush and ask the key questions directly.

"I don't know about our world, but the reason for the birth of the moon in this world should be closer to capture. Am I right?" Tony looked at Miss Li next to him with unusual confidence.

In response to Tony's statement, Miss Li nodded, stretched out her hand to adjust her glasses, and said seriously: "As far as our observations of the moon are concerned, the possibility of it forming naturally is very small. In other words, it is very possible that the entire moon It’s artificially made.”

"Artificial?!"

Both Nozomi and Shimomura Izumi's eyes widened in shock.

After discussing with the scientists during this period, Tony had already speculated on this possibility, so he just showed a smile on his face and did not show any shock.

"As a satellite, the moon is definitely very large. Its size ranks fifth among the satellites in the entire solar system. The largest satellite in the entire solar system is Ganymede. Its diameter is two times that of Jupiter. One-seventeenth. The second largest is Titan, which is twenty-fourths the diameter of Saturn, while the moon is one-fourth the diameter of the Earth. "

Ms. Li looked at everyone present with a serious expression and continued: "As a satellite of the earth, its size is a bit too big. The most thought-provoking thing is its period. As you also know, only one side of the moon faces The back side of the moon that we are on at this time will never face the earth. "

"If you want to ensure that one side of the moon always faces the earth, its rotation and revolution must be exactly the same. The earth rotates for one day and revolves for one year, but the moon is exactly the same. This is the difference. If you think about it carefully, , it’s actually a bit scary.”

Tony kept thinking while listening to Miss Li's words. When he heard her mention the word horror, he blurted out: "It's like an eye that's been staring at the earth. Is this surveillance?"

"Yes, this is also a guess of ours." Miss Li nodded.

"So, what does this have to do with Gantz?" Hope gradually felt a little overwhelmed.

"Let's not talk about this for now, let's continue our topic." Miss Li said expressionlessly: "Another coincidence is that the solar and lunar eclipses are perfect. What seems reasonable and unreasonable is why this shadow is as big as the sun? This is because the diameter of the moon and the distance of the moon from the earth are equal to the ratio of the diameter of the earth to the distance from the earth to the sun."

"To put it simply, the relationship between the moon and the earth is equivalent to the relationship between the earth and the sun in a smaller version. This moon is just in that position, not too close, not too far, not too big, not too small."

"Another point is a very critical discovery. There are many large You know about the big and small craters. But after detection, it is incredible that no matter how big the diameter of the crater is, their depth is six kilometers. This is unreasonable. "

"In theory, large craters are caused by large impacts, and their depth should be deeper. But the meteorites found on the moon, regardless of size, are all six kilometers deep. "

"There are also craters on the earth, but the depth of the craters on our earth is proportional to the diameter, which is completely different from the moon. "

"That is to say!"

Tony suddenly thought of a possibility and looked at Miss Li with wide eyes.

This chapter gave me a headache.

It's rare to ask for votes, please give some.

In addition, there will be extra chapters tomorrow, including two chapters a day, and a total of about five chapters will be updated.
