In the 1980s, the United States published a large-scale album called "The Greatest Adventure of Mankind", which collected the moon photos taken by the 7- 17 spacecraft in the American Apollo moon landing program. A man named Kono; When studying these photos, Kanenki's people found that one photo taken by apollo 8 on the back of the moon was obviously different from other photos. Kanenki framed the suspicious place in the photo and enlarged it. There is something unnatural in the crater of the moon. Can this prove that the moon is hollow?
Let's put aside the hypothesis that the moon is hollow, take a look at the actual situation of the moon and see what conclusions we can draw.
Before man landed on the moon, scientists speculated that the density of moon rocks might be slightly less than that of earth rocks. However, the density of rocks on the surface of the moon brought back by the Apollo moon landing program is much higher than that of the earth. The measured data show that the density of rocks on the surface of the moon is 3.2-3.4 grams per cubic centimeter, while the density of rocks on the earth is 2.7-2.8 grams per cubic centimeter. The lower the moon goes, the higher the density is. The astronauts who landed on the moon for the first time had a hard time planting an American flag in the soil. They took turns shoveling the earth, but they could only insert the flagpole a few centimeters. Several astronauts went to the moon with electric drills, but they could only hit 75 centimeters at most. If they are on the earth, they can hit 360 cm easily. It is obvious that the density of the moon is amazing.
According to this phenomenon, the center of the moon should be a core made of dense matter. In this way, the total mass of the moon will be much larger than that calculated now, and correspondingly, its gravitational intensity will be greater. Considering that the distance between the surface of the moon and the center of the moon is much closer than that between the surface and the center of the earth, and its total mass, the gravity will be much greater than we thought. However, I didn't expect the gravity of the moon to be only 1/6 of the surface gravity, as if the gravity of the moon had nothing to do with its density and mass. What does this mean? This only shows that the moon is a huge hollow sphere.
1969, Armstrong and Aldrin placed a "passive seismograph January earthquake reconnaissance and measuring instrument" on the surface of the moon for the first time, and this instrument was also placed in several subsequent moon landing activities. These instruments work automatically and can send the measured data back to the earth, so that human beings can directly grasp the vibration of the moon. However, when the moon first shook, scientists looked at each other.
When Apollo 13 spacecraft entered the lunar orbit, the astronauts used radio remote control to make the third stage rocket of the spacecraft hit the moon, and its energy was equivalent to the explosion effect of 1 1 ton TNT. The location was chosen at a distance of 40 kilometers from the lunar seismograph 12 placed on Apollo/kloc-0. Strangely, however, this man-made lunar earthquake lasted for 3 hours, and the depth of the lunar earthquake reached 35-40 kilometers. It was not until 3 hours and 20 minutes later that the moon quake gradually disappeared. Seismologists at NASA are surprised that they can't give a scientific explanation for how long the moon earthquake lasted.
Scientists are not satisfied with this conclusion. They used Apollo 14 S-4B rocket to hit the moon, which triggered a three-hour lunar earthquake with a depth of 35-40 kilometers again. After that, the Apollo 15 rocket was used to carry out the lunar shock, and the shock wave spread to the stormy waves 1 100 kilometers away, and even reached the lunar seismograph on the Flemish Plateau. If an earthquake is made on the earth in the same way, the shock wave can only travel 100 km, and there will be no continuous 1 hour vibration.
Let's do a little experiment. If we hit two suspended metal balls, a solid ball and a hollow ball with equal force. The solid ball will make a "buzzing" sound, and the vibration will soon stop, while the hollow ball will not. After its "bang", the shock wave will oscillate along the shell for a long time. The problems faced by scientists are similar. According to several artificial lunar earthquakes, the internal structure of the moon must be different from that of the earth, otherwise similar vibrations would not occur. From the characteristics of the moon's vibration, it is very similar to the vibration of a hollow sphere, otherwise, a small impact will never cause vibration for several hours. Therefore, in the face of this fact, even the most conservative scientists believe that although it is impossible to conclude that the interior of the moon is completely empty, it can at least prove that there are some holes in the interior of the moon.
However, the final conclusion can not be drawn from the above tests, because the shear wave of the moon earthquake alone can not fully explain the problem, and the distance of the lunar seismograph placed on the moon by human beings is too close (because the moon always has its back to the earth, it is impossible to put the lunar seismograph on its back, and even if it is placed, the signal can not be transmitted back to the earth), so the longitudinal wave of the moon can not be measured. If the moon is really hollow, then the longitudinal wave will not pass through the center of the moon, but the transverse wave will oscillate repeatedly on the lunar shell. Scientists hope that a big meteorite will hit the moon. It is proved that the interior of the moon is hollow by measuring the time difference between the vertical seismic wave and the horizontal seismic wave of the moon. Fortunately, this extremely low probability event really happened.
1972 13 in may, a large meteorite hit the surface of the moon, and its energy was equivalent to the power of 200 tons of TNT explosives. Scientists involved in the Apollo program named this meteorite "colossus". The huge lunar earthquake triggered by the colossus did spread to the interior of the moon. If the moon is a solid sphere, this vibration should be repeated several times. However, the facts once again disappointed scientists. After the vibration caused by the colossus was introduced into the interior of the moon, it was like a mud cow entering the sea, and there was no news. There is only one possibility: the longitudinal wave of vibration is introduced into the interior of the moon and then "eaten" by the huge space.
The above research shows that the moon is probably a hollow sphere. What we all know clearly is that according to the theory of the formation of the universe, the naturally formed planet will never be a hollow ball, otherwise, the great pressure will crush it. Dr Sagan believes that "naturally formed satellites should not have internal holes", which is also the general consensus of scientists.
There is a huge space under the 35-40 km shell of the moon. How tempting is this conclusion? What's in it? Are there intelligent creatures like us? What do they live on? Do they farm, too? Why are they there? Do they have electric lights?
If the interior of the moon is really hollow, then all scientific explanations will be useless, and we can only admit the hypothesis of "moon-spaceship".
