PS: Contains a lot of popular science knowledge, but do not order.

Li Hao returned to his office, and he found Ma Yiming, the general manager of the Space Exploration Company, waiting at the door of his office.

He saw Ma Yiming and asked, "Manager Ma, if there is anything that can be reported through the cloud intelligence platform, why did you block me directly at the door of the office." ”

"Mr. Li, I have a big plan to report to you.

This plan was not prepared in advance, and I am afraid that this plan will affect the established development of the company, so I will report to you. Ma Yiming replied respectfully.

Li Hao invited Ma Yiming to his office, and when he was done, he saw Ma Yiming holding a thick folder in his hand.

Li Hao asked curiously: "Now our company is paperless, and documents are rarely used except for contracts. ”

Ma Yiming opened the folder, and inside was a stack of photos, which was a photocopy of the document. You can see that the paper of the document has been yellowed, and the document is written in English.

He introduced to Li Hao: "When Mr. Li talked to me before, I found that Mr. Li was very interested in the moon.

The most in-depth study of the moon right now is the United States. Whether they landed on the moon or not, there is still some debate internationally. But their spacecraft landed on the moon, there is no doubt about it.

This is my selection of the Apollo project team's research data on the moon, as well as the new scientific discoveries on the moon. ”

Li Hao has always been concerned about the moon because his glasses must be irradiated by moonlight. to enter the library of an alien civilization. He had been trying to find out the cause of this phenomenon.

Li Hao took Ma Yiming, sorted out the documents, and he looked at the information recorded in the documents.

Only one side of the Moon is facing the Earth. The Moon's rotation is anomalously axial, with the Moon rotating at a speed of 16.56 kilometers per hour, far exceeding the speed expected of other similar planets.

Moreover, the time of one rotation of the moon is exactly the same as the time of one revolution.

So we can only see one side of the moon on Earth forever, but not the other side of the moon. At the same time, the Moon has no magnetic field.

The gravitational pull of the Earth on the Moon is much smaller than the gravitational pull of the Sun on the Moon. The gravitational pull of the Sun on the Moon is 2.54 times greater than that of the Earth. But the moon still moves steadily around the earth.

Analysis of the surface composition of the Moon has shown that it is not a native object of the solar system.

According to gravitational theory, if the Moon is an alien star, as soon as it enters the solar system, it will first be attracted by the gravitational pull of the huge Jupiter, and it will never run to the edge of the earth.

It is impossible for the Moon to be close to the Earth, not to collide head-on with the Earth, and to orbit the Earth, according to the existing scientific theories, but the Moon is in the sky. The application of scientific theory and reality to the moon has produced a great contradiction.

The orbit of the Moon turned out to be round, and it was close to a perfect circle. And all natural satellites have elliptical orbits.

Except for the Moon. If you think about it, in reality only the orbits of artificial satellites are close to perfect circles.

The Moon is much less dense than planets of the same size, and some of our astronomers have speculated that the interior of the Moon may be empty. This speculation was confirmed in 1969.

At 4:15 a.m. Central Standard Time on November 20, 1969, Apollo 12 conducted an impact experiment on the lunar surface, causing a moonquake.

The moonquake lasted more than 55 minutes. The vibration gradually increases from small to large, and then the amplitude gradually decreases. The tremor was described by scientists as: "It was like ringing a church bell." The shock wave only travels from the epicenter to the perimeter of the moon's surface, but not to the interior of the moon, as it occurs on a completely hollow metal sphere. ”

We did this kind of moonquake experiment a few times later. In the report "Apollo 16 and the Lunar Surface", NASA said that moonquake studies showed that there is a hard layer about 64 kilometers thick inside the lunar crust.

The conduction velocity of vibrations in the interior of the Moon coincides with the conduction velocity of vibrations in metal, leading scientists to speculate that there is a hollow metal shell in the middle of the moon, and that the shell is covered with a loose layer of rocks 16 to 32 kilometers thick.

We also found other corroborating evidence, which came from craters on the surface of the moon.

The study found that if a meteorite with a diameter of several kilometers hits the planet at a speed of 4,800 kilometers per hour, its crater should be 4-5 times deeper than its diameter, as is the case with craters on Earth.

But the crater on the moon is very shallow, the deepest Gargin crater is only 6.4 kilometers, but its diameter is 299 kilometers, and its depth is only 12% of the diameter.

The only explanation for this is that at a depth of about 6 kilometers down the surface of the moon, there is a very hard structure of material that makes meteorites impenetrable.

Then this hard material structure should be a shell made of special metal.

After Li Hao finished reading the expert summary of the Apollo program, he suddenly found that his understanding of the moon was very unfamiliar.

After reading this information, his first thought was that the moon was a product of an alien civilization. He linked up with his glasses, could it be an object left behind by the long-eared man.

He continued to look at the recent exploration of the moon by scientists.

The information on this piece of paper is an excerpt from a review of an astronomer's paper. He mainly argues that the Moon is a large hollow sphere.

Astronomical research has shown that cosmic celestial bodies have magnetic fields that originate from the physical cores of stars. The strength of the Earth's magnetic field is between 0.35-0.7 Oersted.

From the natural remanence of the meteorite, it is inferred that the magnetic field strength of other celestial bodies is 0.59 oost.

That is, all natural celestial magnetic fields, like the Earth, are solid.

However, according to the lunar rock samples recovered by the American Apollo spacecraft and direct measurements of the magnetic field on the lunar surface, the strength of the Moon's magnetic field is less than one thousandth of that of the Earth, which is almost equivalent to no magnetic field. Through this inference, it is indirectly proved that the interior of the moon is empty.

The density of the Moon is small, at 3.33 grams per cubic centimeter, while the density of the Earth is 5.5 grams per cubic centimeter.

This difference is also due to the fact that the interior of the moon is empty. Although the density of the Moon is much lower than that of the Earth, the density of the rocks on its surface is significantly higher than that of the Earth.

Analysis of the lunar rocks brought back by Apollo 11 and 12 revealed that the moon rocks weighed only half the weight of the Earth's rocks. A celestial body with the same gravity environment as the Moon, only the Moon has such a hard shell. This again shows that the interior of the moon is empty.

Astronomical observations show that the faults and fissures on the lunar surface are intersecting in two directions: "northeast, south, west" and "northwest, southeast".

Such directional lattice-like faults and fissures are found throughout the Moon. This is a phenomenon that cannot exist for a natural astral body.

This phenomenon suggests that the interior of the Moon is made up of the same material. and fracture or fusion.

These binding zones are physically different from those of materials, and over the long history of cosmic dust accumulation on this shell has formed this layer of dust on the surface of the moon as seen by people.

The resulting lattice-like fractures and fissures are similar to the accumulation of dust on a soccer ball.

After Li Hao finished reading the entire information, he sighed and said, "I haven't noticed that the moon is so different from other celestial bodies before. ”
