The Earth is called "Earth" only because it is a sphere in itself. The idea that the earth is spherical has become a common understanding of modern people, but you certainly don't know that there are still a group of people who firmly believe that the earth is flat, and even claim that the earth is round is just a lie. What's going on here? What evidence will the "horizon theory" give? If you want to know, let Xiaobian reveal the secret for you:

The survival and reproduction of human beings are inseparable from the earth, in this big home, all things follow the laws of nature and live together in harmony. I don't know when mankind began to notice the earth under their feet and the sky above their heads, because there was no aircraft and satellites to help at that time, people could only conclude from intuitive feelings that the earth was a square open ground, and the sky was a cauldron that was upside down on the earth, which was the famous "round place in the sky" theory.
The emergence of the "round place" theory is no accident, and this conclusion has been reached in the history of all the peoples of the world, such as Greece in the classical period, the Near East in the Iron Age, and the Gupta Dynasty in India, and even the Native Americans. This theory has always been very popular, it is in line with people's primary cognition, representing the exploration of heaven and earth by human civilization at that time.
However, in the course of civilization, there will always be some different voices. Around the 4th century BC, the ancient Greek mathematician and philosopher Pythagoras boldly proposed a theory that the earth was actually a sphere. To this end, Pythagoras also presented six pieces of evidence to challenge the "level theory".
1. When the ship gradually disappears on the horizon, the top of the sail will eventually disappear.
2. When a lunar eclipse occurs, the edges of the shadow projected by the Earth onto the Moon are curved.
3. There are changes in latitude, and the elevation angle of the sun also changes.
4. The elevation angle of the stars in the sky will change with latitude.
5. Natural matter tends to form raindrops or spheres, and the earth is no exception.
6. Travelers who go west from Greece will find elephants, and those who go east will also find elephants, indicating that the traveler circles the earth and returns to the same place. By 1519, the great Portuguese adventurer Magellan had completed the first round-the-world trip in human history, thus proving that the earth was round, completely negating the "level theory" that had been recognized for thousands of years. Until the modern period, as aircraft and satellites have successively ascended to the sky, people can intuitively see the whole picture of the earth in the photos of "God's perspective", and then truly understand and confirm the "circle of the earth".
The emergence of the "earth circle theory" can be consistent with many natural phenomena, such as "four seasons of the year" and "day and night cycle", both of which are the result of the "rotation" and "rotation" of the earth. From the perspective of modern people, in the face of many factual evidence, the "earth circle theory" is almost impeccable, and it can definitely be called a recognized truth. Today, however, there are still some people who firmly believe that the real shape of the earth is not a sphere, but a flattened quadrangular land, which is the current "horizon theory".
Serriol Schenton was a prominent supporter of the "horizon theory", and in 1956 he founded the "International Association for the Study of Leveling" in Dover, England, to attract some members who supported the theory. In 1957, the Soviet Union launched an artificial satellite into space, and Shenton expressed disdain for this historic artificial satellite, and sarcastically said, "Can a ship sail around the Isle of Wight prove that the earth is round?" Satellites are no different! ”。
Shenton believes that the earth is a flat disk, the north pole is located in the center of the disk, and the south pole is an insurmountable wall of ice surrounding the ground, all human activities, can not break through the south pole ice wall, so all the photos taken in space are fake, not at all convincing.
When Shenton died in 1971, its successor, Charles Johnson, took over the International Association for the Study of Leveling Theory. In order to fully collect evidence of the "level theory", Johnson and his wife once measured the curvature of the ocean water body and found that the water body did not show a curved shape, which then proved the correctness of the "level theory" theory. For a long time, the Johnsons and their spouses have spared no effort to promote the "horizon theory" theory, and even they have founded a simple tabloid, "Horizon Theory News", and denounced many of the accepted theories about the earth's information in the newspaper.
In the 21st century, the American Daniel once again openly put forward the correct viewpoint of the "level theory", and even he used the Internet to set up a forum dedicated to the study of the "level theory" for exchanges and discussions among supporters of the "level theory" from all walks of life. However, it is worth mentioning that Daniel's practice of "risking the world" has also attracted the criticism and ridicule of many netizens, but he himself has turned a blind eye to it.
There is still a long way to go on the road to science, and we should have an encouraging attitude toward any scientific doctrine, even if they are only the voices of a few people. But for the 100% wrong theory, but there is really no need to insist, science and technology is progressing, human knowledge theory is also constantly improving, we look forward to tomorrow, the next Magellan will appear, but also do not want some people to not open their minds, with the wrong theory to confuse the public, the result of driving science reversed, can only be in vain, doom.
