The moon is maverick, very extraordinary
For the moon, astronomers have long looked dissatisfied. It is so big that it is disproportionate to the owner like the Earth, just like a big girl looking for a small boyfriend!
Because the owners of all other satellites in the solar system are large and dozens of times larger than the satellite, for example, the largest satellite in the solar system, Ganymede, is 1.5 times the diameter of the moon, but its owner, Jupiter, is 27 larger than it. Times. In comparison, the earth is only three times larger than the moon. This small difference makes people feel that the moon does not seem to be the satellite of the earth, but more like Pluto and its companion star, the moon and the earth are a double planetary system. .
To be honest, in the eyes of astronomers, small planets like the Earth should not have satellites at all. Mercury and Venus will have no satellites. Although Mars has satellites, Mars’ satellites are so small that they are caught by Mars. The big stone that comes.
Another area that is not pleasing to the moon is that the lunar orbit almost coincides with the ecliptic plane. The so-called ecliptic plane is the orbital plane of the Earth. The angle between the lunar orbit and the ecliptic plane is only 5 degrees, and all other satellites in the solar system are honestly rotating around the equator of the planet’s master, even Uranus lying and spinning. Its satellites are also in its equatorial plane. The moon is too maverick at this point, and it seems to make itself as planet-like as possible.
Another maverick thing about the moon is that when people look at it, they feel as big as the sun. We know that the closer the object is, the bigger it feels in the field of view. Although the diameter of the moon is only 1/400 of the sun, it is about 1/400 of the distance between the sun and the earth, which just makes it look in the field of view. It is about the size of a sun disk.
All these weird traits add up to make astronomers think that the moon is extraordinary, it must not be a general satellite!
The surface of the moon appears to be composed of rock and soil and should be about the same density as the Earth. However, the density of the moon is only 0.6 times that of the Earth. So after the two Soviet astronomers Wissen and Schebkov studied the moon seriously, they proposed an amazing view: the moon is a hollow artificial object, an unusually large spacecraft, probably from the distant solar system. Outside the earth’s orbit, the moon has lived a life of wisdom for a long time.
This is a point that is hard to agree with, but it seems that only this point of view can explain all the weird phenomena about the moon. But if you just rely on the above evidence, this view may not be convincing, let us look at the scientific data of various moons.
The moon composition is very unusual
The first is that the composition of the moon is very special.
With the help of spaceships and six round trips to the moon, humans collected more than 30,000 photos and several video tapes, and collected more than 4,000 grams of lunar rocks and soil. According to the composition analysis, the moonstone is interspersed with metals such as chromium, titanium, and zirconium, which are difficult to melt, tough and difficult to corrode. The alloys of these metals together have great heat and impact resistance. On Earth, this alloy can be used to make the inner wall of an electric furnace. If in aviation, this material is used to protect the spacecraft and prevent high temperature, cosmic rays and meteorites from colliding, it is the right material.
The soil on the earth is usually formed by weathering and fragmentation of rocks. The composition is not much different from the surrounding rocks, but on the moon, the composition of the rocks is generally very different from the composition of the surrounding soil – as if the soil is falling from elsewhere On the moon.
Some elements found on the moon, such as a scientific association in Houston, USA, found that the moon samples brought back by Apollo 12 and 14 contained uranium-236 and cesium-237, which were never in the nature of the earth. Found it.
According to the chronological analysis, many lunar rocks are older than earth rocks. The age of the earth is considered to be 4.5 billion years, and some moon rocks are more than 5 billion years old. The most accurate method is used to measure, and some moonstone ages even reach 7 billion years!
These indicate that the moon is likely to pass through in space, receiving material dust and gravel from different ages and different universes.
Moon vibration like a bell
The reaction when the moon was hit was also shocking.
For example, once the Apollo 12 astronauts returned to the orbit after returning to the orbital module, the shock caused by the impact of the lunar module on the moon lasted nearly an hour. The impact of the Apollo 13 propeller on the moon caused the moon to continue to vibrate for 3 hours and more than 20 minutes. Apollo 14 also hit the lunar ground under the remote control. NASA’s publication said that the moon is like a large spherical gong. It has been shaking for more than three hours and the vibration has reached about 40 kilometers. deep.
The vibration of the moon not only lasts for a long time, but the vibration mode is also very strange.
The amplitude of the shock wave is small at the beginning, gradually increases to the highest point, and then slowly decays for a considerable period of time. This type of seismic wave has never been transmitted on Earth. An earthquake on Earth lasts for a few minutes and starts with a very strong shock, and then decays quickly. On Earth, the vibration continues, and the amplitude increases first and then decreases. It usually appears on tough, elastic and hollow objects, such as bells, gongs, drums, etc.
The speed of vibration inside the moon is also strange. It will continue to grow with the depth of propagation. It will suddenly increase after a certain depth, which means that the density of matter there is also suddenly increased. In the depth of tens of kilometers, the wave propagation The speed is about 10 kilometers per second, and no rock can propagate seismic waves so quickly. So what material is that part made of? After testing, the sound velocity in the alloy of iron, titanium, tantalum, molybdenum and niobium is 10 km / sec. Is it composed of these metals under the surface of the lunar surface?
What is even more incredible is that the mode and period of the moonshine are very regular, and the time between each vibration is the same, just like the clock. Five days before the moon reaches the perigee (the position of the moon closest to the Earth), a monthly earthquake caused by the burst of the rock will appear, and the earthquake will appear once again three days before reaching the perigee. According to the explanation of the moon experts, the tidal force of the Earth on the moon will gradually accumulate until the friction between the moonstones is unbearable, and it will explode and slide against each other to cause vibration. However, on Earth, earthquakes are caused by factors that are considered to be extremely complicated and unpredictable. However, on the moon, the moon earthquake does not need to be predicted. Just like the moon has a strict timetable, the moon earthquake arrives on time.
These phenomena indicate that the possibility of hollow inside the moon is very high.
