With the continuous progress of human society, our exploration of the earth and even space is also ongoing. So far, the pace of human exploration has never stopped. And the mystery of the world is not disappointing. No, the United States has found such a mysterious and strange phenomenon. Let’s take a look at the following!
In the early 1960s, an American spacecraft was on a mission in space. When the spacecraft passed over Africa, the astronauts observed a strange phenomenon in the space hundreds of kilometers away from the earth: a round object appeared on the earth, and it was staring at the space with round eyes.
When they saw the strange big eyes, they were shocked. From the images they took, the pupils of the big eyes were so lifelike that they made people think deeply.
This “eye” is divided into three layers: the most central circle, like a pupil, with slight cracks on one side; the most peripheral circle, like a pupil, is larger, which tightly surrounds the middle circle, like a round eye; the most peripheral circle, of course, is the eyelid. What’s more, there is a ring outside the big circle, just like an eye.
The astronauts immediately sent this picture to the researchers on the ground for them to find out. After receiving this picture, the ground crew was very shocked. After careful comparison, they finally confirmed that the giant eye was in Mauritania, southwest of the Sahara desert in Africa, the largest desert in the world.
To find out, the researchers decided to make a field trip to find out what happened and what secrets were hidden. After further exploration, we learned that the giant eye has a diameter of 48 kilometers and a height of about 400 meters. It looks very flat on the whole. It is surrounded by some low hills. In the distance, it is a piece of yellow sand. Because of its shape like eyes, also known as the “eye of the Sahara.”.
After a lot of exploration work, geologists believe that this “giant eye” is a natural phenomenon. This is due to the formation of both uplift and erosion. It turned out that there was a hard layer of rock under the Sahara yellow sand. Thousands of years ago, due to geological movement, the rocks under the desert were lifted up, exposing the top of the sand. Under the action of wind, sunlight and rain, a huge depression is gradually formed after the rock strata are exposed to the ground.
Because of the different rock structure, the degree of erosion is also different. Under the same natural conditions, the degree of erosion of hard rocks is relatively light, especially some Paleozoic quartzites with high hardness and not easy to be eroded remain basically unchanged. Moreover, the soft rock has been seriously eroded, forming huge holes. Coincidentally, the eroded rock just formed three concentric circles, so this strange “eye” appeared.
However, some people are still convinced that this mysterious “giant eye” is related to a lost civilization. Researchers believe that the “eye of the Sahara” is not only a city lost by the ancient Atlantis, but also a water city. The reason why it became a water city is that the formation of its geological structure must be related to water erosion.
But scientists can’t answer this question, because these things are beyond human understanding. But Xiaobian thinks that in the near future, this mysterious giant eye will be unveiled. Let’s see what it looks like.
