I dare not say that my views and research are great and unique, but I can present my opinions and hypotheses. Na Linwan said with relish: I can prove my research and my point of view with a set of data. You see, the diameter of the Earth is 12,756 kilometers, and the diameter of the Moon is 3,467 kilometers, which is 27% of the diameter of the Earth; Mars has a diameter of 6,787 kilometers and two moons, the larger one is 23 kilometers in diameter, which is 0.34% of the diameter of Mars; Jupiter has a diameter of 142,800 kilometers and 13 moons, the largest of which is 5,000 kilometers in diameter, which is 3.5% of Jupiter's diameter; Saturn has a diameter of 120,000 kilometers and 23 moons, the largest of which is 4,500 kilometers in diameter, which is 3.75% of the diameter of Saturn. None of the other planets have moons that are more than 5% the diameter of their parent planet, but the Moon is 27% larger, what does this mean? This shows that the Moon is not an ordinary celestial body.

Uncle, can't you see any special phenomena on the moon from these data? Yang Momo asked puzzledly: This can only show that the moon is the largest satellite in the universe; Earth's smallest moon is the largest.

No! That's not true! Narinwan immediately corrected and explained: It is generally believed that the moon revolves around the earth, but it is not.

Yes? Yang Momo was very shocked: This is your discovery again, uncle? What the hell is the secret?

We all know that the Earth rotates from east to west, while the Moon, on the contrary, rotates from west to east, but with the Earth in opposite directions. And it's very fast. We all know that the high-speed rotation of matter will produce centrifugal phenomena, if there is no moon reversal, then the rivers, lakes, seas, and oceans on the earth will be thrown away and escape into space, and the earth will become as desolate as Mars. The reversal of the Moon's rotation ensures that water on Earth cannot escape, creating a perfect atmosphere for Earth. The Moon also influences the Earth's tides by reversing the rotation, giving the greatest impetus and help to the balance and transportation of the Earth's water level. This is something that no human can and absolutely cannot achieve. The earth is the mother that nurtures life, and the moon is the mother that cares for life. The Earth and the Moon seem to be twin sisters. Isn't it strange that the orbit of a natural satellite is elliptical, but the orbit of the moon is circular, with an orbital radius of 380,000 kilometers? Because only the orbit of the Earth's artificial satellite is circular.

And uncle, this is what you want to prove that the moon is also an artificial satellite? Yang Momo was very surprised and asked: How did such a large satellite be built? And who made it?

Na Linwan pondered for a moment and continued to explain: I can answer you. The Moon is much less dense compared to planets of the same size. It's different from other planets, and I think it must be empty inside. The reason is that the gravitational pull of the Earth on the Moon is much smaller than the gravitational pull of the Sun on the Moon, but the Moon is not attracted by the Sun, but remains in the orbit of the Earth. If the Moon is a natural star in the universe, then as soon as it enters the solar system, it will be attracted to Jupiter or other stars, and will not run to the side of the Earth. Therefore, there is only one conclusion, the Moon is not a naturally formed planet, but an artificial celestial body. To this day, I believe that there is a mysterious force in the universe that controls the moon. Perhaps one day of the year, the moon will be taken back by this mysterious force. It's like the earthlings taking back the satellites. Today, scientists have observed that the moon is fleeing the Earth at a speed of 2.4 kilometers per second. It seems that there is a mysterious power calling the moon home.

So who paid so much money to build the moon moon, and what is its purpose? Yang Momo was still puzzled, frowned and asked: Uncle, the construction of the moon is really incredible! It's a little scary to say that.

However, this is not meaningless construction, nor is it incredible, but significant! Na Linwan asked Yang Momo sternly: You answer me, what is the purpose of the earthlings to build satellites?

This is a lot, national defense, science and technology, communications, agriculture, industry, etc., are now inseparable from satellites. Yang Momo replied without thinking: Network satellites have brought everything today! Without network satellites, we would not have been able to come to the moon.

That's right! Na Linwan said with great interest: The moon also has the value of a man-made satellite that is even more than a thousand times more than that of the earthlings, and it is a space station, a transit station, and a space base set up by aliens in the universe. The network system on the moon is the most mysterious, complete and perfect network system in the universe, and any spacecraft must visit the moon. Because here you can get maintenance, repair, and replenishment of energy. The moon is a beacon in the vast universe, like a beacon on the ocean. Also, why do I say that the moon is the caring mother of life on earth, you can see from some photos that for billions of years, the moon has been hit by aliens and asteroids, and it is full of holes and scars, why? That's because the Moon is the best shield for the Earth! As a younger sister, she is dutifully guarding the earth sister in obscurity, even if she is covered in bruises, she has no complaints! Without the Moon, I am convinced that even if the Earth existed, there would be no life. Pain on the moon, happiness on earth!

That uncle, you are too wise, your thinking is different from ordinary people! Yang Momo was still confused and asked: You said that the moon is hollow, how can you prove it?

In addition to the gravitational attraction I just mentioned, sound can also prove that the Moon is hollow. Na Linwan unreservedly explained: This involves another discipline. We all know that seismologists usually use seismic waves to study the properties of the Earth's interior. Similarly, astronomers and scientists have been inspired by seismic waves to study the properties of the Moon's interior with lunar seismic waves. When astronauts landed on the moon, they used the lunar surface as a base, and they set up high-sensitivity seismographs to send moonquake data back to Earth. Don't underestimate such a seismograph, its high sensitivity performance is even able to record the footsteps of astronauts on the lunar surface. The astronauts hit the surface of the moon with the ascent of the lunar module, and a moonquake followed. During the tests of a highly sensitive seismograph, the moon shook for up to 55 minutes. The vibration changed from small to large, and it was as long as 8 minutes when the vibration intensity was at its highest. Then the amplitude gradually decreases until it disappears. This process actually took almost an hour, and listened to it under special amplified voice control, and the aftermath lingered and endured. What does this mean? Scientists were amazed and surprised. They said it was like ringing a huge hanging bell. Their study showed that lunar seismic waves only propagate from the epicenter to the periphery of the moon's surface, but not to the interior of the moon. It's like a sound wave struck on a completely hollow metal sphere. No matter how much it hits and knocks on the earth, it is absolutely impossible to make a sound. This is ample proof that the Moon is hollow.
