Typical science fiction is based on reasonable or unreasonable speculation. It describes the role of exploring, discovering, understanding and testing things in a certain time and space in a scientific way (observation, hypothesis and experiment) through projection, reasoning, analogy, hypothesis and demonstration, and usually reflects people's position in the universe and the relationship between people and the universe in reality.
"Scientific form" can also be used in the name of fantasy, such as describing a magician observing, analyzing and experimenting with scientific and technological products such as airplanes in a magical way of thinking. In science fiction works, there can also be knights who regard the train as a dragon and spears and gladiators as the bridge of the car, but if this idea is used too much, readers will be aesthetically tired.
The birth of science fiction literature;
Science fiction literature was basically born after the industrial revolution. People obviously feel that the development of science and technology has changed the mode of social production and their own way of life, and promoted social change.
Therefore, people will inevitably think of the future technology and its influence on human beings. Anxiety and longing make people think, so most science fiction novels will describe the future, and most of them will introduce inferences in reality and unfinished scientific and technological achievements. Among them, works containing scientific knowledge provide readers with knowledge, stimulate positive scientific thinking and bring new ideas.
