Ancient China: the theory of covering the sky (mainstream understanding: the sky is round, and it covers the earth like a hemispherical cover), the theory of muddy sky (Zhang Heng in Han Dynasty thought that the sky was like a chicken, and the earth was as yellow as it was), and the theory of Michelle Ye (Teacher Miao Meng in Jin Dynasty thought that the sun, the moon and the stars naturally floated in the void, and there would be life when walking on it).
Ancient India: Irregular circle (Buddhist scripture: Arahant Analu knows the southern part of the mainland like the back of his hand), said the floating turtle (the earth is carried by four elephants, and there is a turtle and a big snake below. )
Ancient Greece: floating island theory (the earth floats on the water), spherical celestial bodies (ptolemaic system)
Ancient Egypt: People believed that the goddess of the earth supported the earth in the underworld.
In addition, there is a saying that Hercules holds up and whales hold up.
These understandings more or less reflect the objective facts: for example, the floating island theory is consistent with plate drift, which can explain the earthquake phenomenon well; Huntington's theory is very similar to ptolemaic system's, which holds that there is a hard celestial sphere orbiting the earth; Michelle Ye said that the stars hang in the dark space and the universe is infinite; Ptolemaic system, whose constellation system can well explain the relative position of the earth and stars in the universe.
In fact, the ancient sages in China were all very powerful, but unfortunately they were superior and were often laughed at and suppressed.
Worrying about the sky is obviously a subconscious concept of gravity, but it is ridiculed as much ado about nothing.
If conditions permit, that person reaches the North Pole, then continues to find that the direction is south, continues to reach the South Pole, and finds that the direction is north, and finally returns to the starting point to complete the round-the-world trip, proving that the earth is round.
I can disagree with you, but I will defend to the death your right to express your opinion. Unfortunately, under China's autocratic Confucianism, dissidents are excluded, despised and suppressed.
