The diameter of the sun is 400 times larger than that of the moon, and the distance is also 400 times. Is everything really a coincidence?

do you know? Compared with the sun, the moon is actually as small as a sesame seed, so what is their specific size? How much bigger is the sun than the moon?

The ancients often said that the sun and the moon shine together, comparing the sun to a lantern, while the description of the moon, the full moon is a silver plate, the half moon is a sickle, and it is a boat. From these descriptions of the sun and moon. It is not difficult for us to see that in our vision, the sun and the moon are the same size, which is the same size as a basketball.

The diameter of the sun is about 1.392 million kilometers. What is this concept? The diameter of the sun is equivalent to the diameter of 1.3 million earths, and the diameter of the moon is 3,476.28 kilometers, which is one forty-ninth of the earth. The diameter is one-fourth the diameter of the sun, that is, the diameter of the sun is 400 times the diameter of the moon. However, in our vision, there is no difference between the sun and the moon, so the ancients had to sigh "the sun and the moon are full of clouds in the west, the moon rises in the winter and the silver town; the sun is beautiful in the mountains and rivers, and the moon is full of lakes and seas."

In fact, the reason why we feel that the size of the moon is similar to that of the sun is related to our eyeballs. Our pupils can see things clearly by adjusting the interpupillary distance. Human eyes are similar to convex lenses, and the retina is equivalent to the image plane. When we see an object clearly, we must make its image fall on the retina. The angle of view at the center of the pupil of the human eye is the same as the opening angle, and the size of the angle of view determines the size of the object seen. The same object, the viewing angle far from the eye is small, and it looks small. A simple explanation is the concept of near big and far small. It is precisely because the sun is far away from us, and the moon is close to us, as if a single leaf is blinding the eye.

You know, the sun is about 150 million kilometers away from the earth, and the distance between the moon and the earth is about 380,000 kilometers. So the distance from the sun to the earth is exactly 400 times the distance from the moon to the earth. Although in the universe, the sun and the moon are of different levels, in the age of technological backwardness, people can only see believing.

As humans have landed on the moon, they have learned more and more about the moon. For example, the fact that the moon is hollow has subverted many people's cognition. What other well-known secrets does the moon have?

The moon has been a poetic celestial body since ancient times. It accompanies lonely people, gives hope and fantasy at night, and makes more and more relevant experts dare to explore it.

In the 1960s, the "Intrepid" lunar module of "Apollo 11" suddenly lost control and fell on the surface of the moon, and there was a seismograph more than 70 kilometers away from the crash site, which just recorded this last quarter of an hour. sound of impact. In theory, a solid moon should only take 3 to 5 minutes. At that time, the 15-minute "moon bell" showed that the moon was hollow. This coincidence also became the biggest discovery of the US and the Soviet Union when they landed on the moon. The most classic moonquake experiment. Because when a solid object is hit by other objects, two kinds of waves can be generated, a surface wave and a longitudinal wave. Longitudinal waves are penetrating and can travel from one point to another through the heart of an object, while surface waves travel on extremely shallow surfaces. In their experiments on the moon, only surface waves were obtained, but no longitudinal waves. It can be seen that the moon is hollow.

It is worth mentioning that when the astronauts landed on the moon and landed, they would hear the bell, which is the same as the church bell, which makes people have to think that the lunar outer shell is made of a special metal, and the whole moon is like a mouthful of super. big clock.

Plus, there's some coincidental data on the moon. The Moon's rotation period, the Moon's orbit coincides with its orbital period around the Earth. The rotation speed of the equatorial part of the earth is about 1600 kilometers per hour, while the equatorial part of the moon is less than 17 kilometers per hour. Although the rotation speed of the two is very different, they are still "adjusted" just right, and the moon faces the earth in the same hemisphere.

Regarding the moon, there are too many coincidental data. At present, only the moon is so unique among the celestial bodies that humans can observe. One has to wonder if this is just a coincidence? Also said who designed it according to some requirements?

Asimov once said, "The moon is just big enough to cause a solar eclipse, and small enough to still allow people to see the corona, and there is no astronomical reason to explain this phenomenon." There are also some coincidental data, coincidental The impact has to make people question "the moon shouldn't be there". After all, it is difficult for people to believe that such coincidences were formed naturally.

In the solar system, only the earth has such a huge satellite, and the satellites in other planetary belts are either small or not. The moon is similar to the earth, which makes people have to guess whether the creatures that appear on the earth will also have the moon among them. What about credit? Or are there creatures we haven't explored that are behind it all? We don't know this, after all, to the universe, our life is just a mayfly.
