●Moonquakes: Earthquakes that occur on the moon. Since ancient times, the moon has inspired many beautiful imaginations of mankind. Chang'e flies to the moon and the Jade Rabbit makes medicine. Although it is "cold at high places", there is also "a different world." Such a beautiful legend seems to tell people that the beautiful jade plate in the sky is "lonely" and "empty". So, what does the moon look like? How is a lunar eclipse formed?

The discovery of hollow spheres

Before humans landed on the moon, people always believed that the moon was a dead world. Since the Apollo 11 spacecraft first landed on the moon in 1969, people have learned that the moon is not peaceful, but an extremely active world. Moreover, nearly a thousand moonquakes occur on the moon every year. According to the long-term records of moonseismometers, the intensity of moonquakes is not large compared with earthquakes. Generally, the energy of moonquakes is only equivalent to a magnitude 1 to 2 earthquake. The largest moonquake recorded so far was only magnitude 4.8. What is strange is that a small earthquake of the same magnitude can only last about 1 minute on the earth, but it will last about an hour on the moon, and sometimes it will subside after several days. Many scientists believe that there is only one explanation for this strange phenomenon - the moon is hollow.

In 1949, Dr. Wilkins of the Royal Astronomical Society of the United Kingdom predicted that the moon is likely to be hollow, and its internal cavities must be interconnected. Those huge circular caves are the gateways for alien spacecraft to enter and exit the moon. In his book "Our Moon", he calculated that the volume of the lunar cavity is about 58 million cubic kilometers. But Wilkins's astonishing insights did not attract enough attention from the world at the time.

Human beings detected the phenomenon of life on the moon for the first time, and took photos that were suspected to contain signs of water and life. Since then, humans have conducted new explorations of the surface of the moon, and also inspired the theory that the moon is hollow.

Almost all naturally formed celestial bodies in the universe are solid, and only man-made celestial bodies, satellites, and spacecraft may be hollow. One obvious difference between solid and hollow objects is the different sounds they make when struck by foreign objects: solid ones are dull and short, while hollow ones are crisp and long. If conditions permit, the sound of the hollow object may even echo melodiously, making it pleasant to the ear. Of course, moonquakes are not the only evidence that the moon is hollow. The density of lunar rocks can also explain the problem. Generally speaking, the moon formed almost at the same time as the earth, and its internal structure should be close to that of the earth, with a lunar crust, a lunar mantle and a lunar core.

According to conventional reasoning, the density of the moon seems to be the same as that of the earth, showing a pattern of getting higher toward the inner layer. If the density of the moon is higher than that of the earth, then the moon's mass may be greater than the same volume of earth's soil, and vice versa. However, the actual data is contrary to people's assumptions. It has been determined that the density of rock specimens retrieved from different locations on the moon is 3.3 grams cubic centimeters, which is 15% to 20% higher than the density of surface rocks. It stands to reason that the average density of the moon should be greater than that of the earth. But the moon's gravity is only 1/6 of the earth's, which is suspicious. According to calculations based on celestial mechanics data, the moon's mass is about 40% lighter than the same volume of earth's soil. Since the surface of the moon is heavier but the mass of the entire moon is lighter, there is only one reasonable explanation for this phenomenon. There is a huge cavity inside the moon. Numerous experiments in the field of astrophysics have confirmed that a naturally formed sphere cannot be hollow. In other words, a hollow moon will not form naturally.

Many astrophysicists insist that the moon is likely to be the product of aliens, and that the moon itself is an incomparably large "hollow spacecraft." The operating parameters of the moon are also wonderful. For example, the diameter of the moon is 1/400 of the diameter of the sun, and the distance from the moon to the earth is also exactly 1/400 of the distance from the earth to the sun; the orbital plane of the moon around the earth and around the sun Exactly coincident, the size of the moon and the sun during a total solar eclipse are exactly the same; as a satellite, the size and mass of the moon are simply too large, and such a huge planet will be attracted by the earth, which is only 4 times its diameter; many moons The sea is as flat as a pool table, and it is difficult to say that this strange topography is entirely natural.

Some people believe that it takes 28 days for the moon to orbit the earth once and 28 days for one rotation. This means that one side of the moon always faces the earth and the other side always faces away from humans, which is also very strange.

There is a lot of sophisticated analysis and strange talk. This may just confirm the famous saying: "The more we know about the moon, the more we realize how complex a celestial body it is.
