The Earth was an irregular sphere with a slightly flat pole and a slightly bulging equator. There was no so-called " end ". The Earth was a closed three-dimensional space. No matter which direction one traveled along the Earth's surface, they would eventually return to the starting point. There was no such thing as a circle at the end.
The Earth was an irregular sphere with a slightly flat pole and a slightly bulging equator. There was no such thing as an end. In some artistic creations, imaginations, or specific context," the end of the earth " might be given a special meaning. For example, in the comic " The End of the Earth," it was the background concept of the protagonist's adventure during the interstellar crisis. In the historical events of Spain and Portugal dividing the Earth, the so-called " end of the earth " was also an exaggerated expression to describe their division of the unknown regions of the world. But from a scientific point of view, the Earth had no end.
In " Earth's End," Planet Pebble was a planet ruled by dinosaurs, and the Divine Dragon was the overlord of Planet Pebble. It had a high status and great power in the parallel world it lived in, but there was not much detail about the Divine Dragon.
On Earth, the sky and the ground that we can see overlap with each other. This is because of the existence of the atmosphere, which forms a spherical encirclement that wraps the Earth in it. Therefore, we usually think of the earth as a spherical object. However, when photos were taken from space, due to the lack of an atmosphere, they usually showed the outline of the Earth instead of a complete sphere. This is due to the lack of atmospheric refraction and scattering of light in space, so the light can directly pass through the surface of the Earth and form an outline in the photo. Although the Earth is not exactly spherical in shape, we can see the outline of the Earth in pictures taken in space, rather than a complete sphere.
The lyrics of " Round Earth Song " were: " Earth, earth, the blue planet we live on, friends and family, everyone, this is my home, oh oh; Earth, earth, the blue planet we live on, friends and family, everyone, this is my home, oh oh; There are so many animals in the sea and in the sky. We go around the sun and it shines. The song was from the album "Our Planet OST Part 2", and the lyrics and composition were written by.
The Earth was not flat, but an irregular sphere with a slightly flat pole and a slightly bulging equator. Ancient people had a saying that the sky was round and the earth was square based on their intuition because of the small range of activity. However, with the development of science, many pieces of evidence showed that the earth was spherical. For example, through the phenomenon of ship navigation, aristotle proved that the earth was round. Magellan's round-the-world voyage and the invention of the telescope by galileo also proved that the earth was round. Modern measurement technology further confirmed that the earth was an irregular sphere. Its equator radius was 6378 kilometers, and its polar radius was 6357 kilometers. The difference between the two was 21 kilometers, with an average radius of 6371 kilometers, a maximum circumference of about 40,000 kilometers, and a surface area of about 510 million square kilometers.
This described the phenomenon of the earth revolving around the sun. The Earth revolved around the Sun in a fixed orbit. Its orbit was an oval orbit with an average radius of about 150 million kilometers. The center of the revolution was the common center of mass between the Earth and the Sun. The direction of the revolution was from west to east, and the revolution period was one year. Because the orbit was oval, the distance between the Earth and the Sun changed during the revolution. The closest position to the Sun (perihelion) was generally in early January after the winter solstice, and the farthest position from the Sun (aphelion) was generally in early July after the summer solstice. The plane on which the Earth revolved was called the ecliptic plane. When the Earth revolved, its axis tilted and its direction did not change, causing the amount of sunlight and heat obtained at different times and places to be different, resulting in the change of the four seasons. According to the amount of sunlight and heat obtained by different places, the Earth's surface was divided into five zones: the tropical zone, the northern temperature zone, the southern temperature zone, the northern frigid zone, and the southern frigid zone. During the Earth's revolution, there were two cycles, the tropical year and the stellar year. The difference of one year between the two was called precession.
The Earth was not a perfect sphere, but an irregular sphere with a slightly flat pole and a slightly bulging equator. In ancient times, people were limited by the scope of their activities, so there was a saying that the sky was round and the earth was square. Pythagoras of ancient Greece believed that the Earth was round. Later on, through the phenomenon of ships sailing into the ocean (no matter how the direction of travel changed, the first thing that disappeared from the observer's field of vision was the hull), he proved that the Earth was round. Magellan's round-the-world voyage, and the invention of the telescope by Galilei also further proved that the Earth was round. With the development of measurement technology, satellites measured that the Earth's equator radius was 6378 kilometers, and the polar radius was 6357 kilometers. The difference between the two was 21 kilometers. It was clear that the Earth was an irregular sphere with a slightly flat pole and a slightly bulging equator. Its flattening was 1/298. Although the Earth was not a perfect sphere, from a macro perspective, it could be said that the Earth was round. In addition, global warming caused the melting of the Arctic and Antarctic ice sheets on a large scale. This phenomenon was changing the shape of the Earth, but the Earth was still in the shape of an irregular sphere with slightly flat poles and slightly bulging equator.
He recommended a few novels. "I Raise an Earth", a sci-fi interstellar civilization novel created by Yue Yubai. The main character was Earth, birthday 06/05, Gemini. It was a story about interstellar dust, the sprouting of life on Earth, and the development of civilization. The book list had a comment on the emotional drama, but the creative writing was good. "Digging the Earth", a supernatural urban novel written by Fu Bao. The protagonist, Zhou Yun, explored the unsolved mysteries of the earth in search of treasures. The book list commented that the plot was good, but the author liked to be a eunuch. The style of the novel was more refreshing. "Two-week Female Empress: Something's Wrong with the Plot!" It was a light novel written by Strawberry. Li Yunsheng transmigrated to become the chief assistant and fought with the empress. The plot was interesting but the setting was messy. "Infinite Awakening from Uncle Nine's World" was a sci-fi novel written by cumin kebabs. It was about the male protagonist, Wang Fan, in the reincarnation space. "Earth No. 7 Strategy" was a science fiction space novel created by Yun Mou. The encounter of the seventh on Earth was very funny, but it was just a ten-thousand-year-old pit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
"The sky is round and the earth is square, and there are nine laws" was a common starting phrase for Taoist spells. Its complete description was as follows: " The sky is round and the earth is square, and there are nine laws. I write now, ten thousand ghosts are hidden "and so on, followed by some sentences with Taoist magic meaning, such as" Second than the ancestral sword, mobilize the heavenly soldiers." Three strokes of the fierce god died, what ghost dare to see, what evil dare to bear. It was reflected in Taoist rituals or legends. It might be used in ritual situations such as exorcism and inviting gods to descend.
