Earth is a prison theoryThe Earth Prison Theory was a hypothesis. The hypothesis was that Earth might be a prison in the universe, created by aliens or extraterrestrial intelligent civilizations. The purpose was to imprison souls who had committed crimes in the universe and hope that they would learn to repent on Earth. The person who proposed this hypothesis was the American ecology non-authority, Alice Silver. He proposed the theory that " humans did not come from Earth " based on the many ecological characteristics of humans that were not adapted to the Earth, such as the Earth's gravity making people feel uncomfortable and the inability to continue to be exposed to the sun. He believed that human ancestors were actually exiled to Earth from other planets. Earth's gravity and the lack of oxygen in outer space caused humans to remain on Earth, like a giant prison. In addition, some people believed that the buildings of civilization on Earth, such as the pyramids, might be related to the Earth Prison Theory. However, there was currently no evidence to support the hypothesis that " humans did not come from Earth " and the Earth Prison Theory proposed by Alice Silver. These views could only be explored after the advancement of human technology in the future.
Earth Cage TheoryThe Earth Cage Theory contained many different perspectives. One view was that the Earth's natural environment had many restrictions on humans. For example, humans were relatively fragile, weaker than bears, slower than cheetahs, and had no sharp claws. Falling from a height of one or two meters could kill them, and most people would drown. Earth had gravity. Although this allowed humans to survive stably, it also greatly increased the difficulty of humans escaping Earth. Space exploration consumed a large amount of Earth's resources and might affect their own food and clothing. At present, only Earth was suitable for human survival. Once they left Earth and without external research and development equipment, it would be difficult for humans to survive.
There was also a hypothesis that the Earth might be a cage for alien civilizations. The ancestors of humans might have been aliens. They landed on Earth after encountering problems during flight and were trapped here, unable to return to their hometown. In this sense, humans were aliens. There were also American ecologists who suggested that Earth might be a prison in the universe, built and supervised by a highly intelligent civilization. The moon might be used to monitor humans, and humans seemed to be incompatible with the Earth's environment. From a biological point of view, humans needed to use many tools to adapt to different environments on Earth. Human lifespan was also limited by factors such as the number of cell divisions. These were all seen as evidence that Earth might be a cage. There was also a view that the solar system was a cage because the solar system was wrapped in a mysterious giant bubble. There might be a bigger " cage " outside the universe.
The hollow earth theory was confirmedMost scientists believed that the Earth was a solid celestial body, and the theory of a hollow core was considered pseudoscience. There was no evidence to prove that the Earth was hollow. Although there were phenomena such as the discovery of mysterious caves in Vietnam and the discovery of mysterious caves in Antarctica that led people to speculate about the hollow Earth theory, these were not enough to prove the hollow Earth theory.

Can the Wandering Earth Theory be realized?From a scientific point of view, some of the settings in Wandering Earth were difficult to achieve.
In the original novel and the movie, the reason for the Earth's wandering was that scientists had observed the accelerated evolution of the sun's core, which would erupt in a short period of time and engulf the Earth and other solar system planets. However, the current understanding of the evolution of a single star with the mass of the Sun was quite clear. Theoretically and observably, it was not supported that the Sun would undergo the kind of changes in the movies in the next few hundred years.
Regarding the propulsion of the Earth, whether it was based on the original description or the movie, the thrust generated by the planetary engine could not shake the Earth. Before the propulsion succeeded, the Earth might have been destroyed by the geological disaster it brought. The planetary engine could not make the Earth leave the solar system.
Therefore, from the perspective of realistic scientific theory, the Wandering Earth theory was difficult to realize, but as a setting in science fiction, it was full of imagination and science fiction elements.

The reason why we object to the flat earth theoryThe flat earth theory believed that the earth was a flat or flat structure. However, modern science had proved that the earth was nearly spherical through various evidence, which was also the reason for opposing the flat earth theory.
First of all, looking at the curvature of the horizon, when people observed the horizon, they would find that ships or other objects gradually disappeared on the other side of the horizon as the distance increased. If the Earth was flat, objects should always be visible. However, the actual situation was that when the observation point was raised, the horizon would curve, which implied the curvature of the Earth, which contradicted the theory that the Earth was flat.
Secondly, his sailing experience also provided evidence. During the voyage, navigators and explorers discovered that ships gradually disappeared when they left the coastline and gradually appeared when they approached again. This phenomenon could be explained as the ship disappeared behind the curved surface of the Earth and reappeared in front of the curved surface, rather than the flat surface theory that the Earth was flat.
Furthermore, through astronomical observations of the movement of other planets and satellites, as well as an understanding of the gravitational interaction between planets, scientists constructed more accurate models of the universe. These models showed that the Earth was actually an oval, not a flat structure in the flat earth theory.
Finally, the development of aviation and space exploration allowed humans to directly observe the shape of the Earth. The pictures taken from space showed that the Earth was a sphere with protruding poles and spherical curvatures, which did not conform to the flat earth theory.

Literature theory, creation theory, noumenon theory, reception theory, what else?Literature theory includes creation theory, noumenon theory, and acceptance theory. The specific differences are as follows:
Creation theory refers to the theory of the basic principles and methods of literary creation. It paid attention to the process of producing literary works, the psychology of creation, and the methods of creation.
Ontology is the theory of existence, noumenon, and essence in philosophy. In literary theory, noumenon usually refers to the theory of literature itself and its existence. It explored the essential features of literature such as language, structure, theme, and style.
3. The theory of reception refers to the theory of literary acceptance and readers 'response. It focuses on the readers 'reaction and acceptance of literary works in the process of communication, and probes into the value and significance of literature.
In addition, there were also some theories related to literary theory such as aesthetic theory, cultural theory, ideology theory, etc. They discussed literary phenomena from different perspectives, which had a profound impact on the development of literary theory.
