What is science fiction
Typical science fiction is based on reasonable or unreasonable speculation. Through projection, inference, analogy, hypothesis and demonstration, it describes the role of exploring, discovering, understanding and testing things in a certain time and space in the form of science (observation, hypothesis, experiment), usually reflecting the status of people in the universe and the relationship between people and the universe in reality. "The form of science" can also be used in the name of fantasy, for example, to describe magicians observing, analyzing and experimenting with scientific and technological products such as airplanes in a magical way of thinking. In science fiction works, knights can also see trains as giant dragons, mantis with long spears as chariots, etc., but this idea will make readers tired. Science fiction literature was basically born after the Industrial Revolution. People clearly feel that the development of science and technology has changed the way of social production and their own way of life, and promoted social change. Therefore, people will inevitably think of the future science and technology and their impact on mankind. Anxiety and longing urge people to think, so most science fiction will describe the future, and most of them will introduce inference and unfinished technical achievements in reality. Among them, works containing scientific knowledge provide knowledge for readers, stimulate positive scientific thinking, and bring new ideas. Science fiction is not bound by traditional social thoughts and can freely explore various social concepts and scientific concepts. However, the reactions of characters, societies, civilizations and species in the book to various things will show the author's understanding of these things in a specific era background and scientific level. Some authors are willing to explore ways to solve practical contradictions, while others are willing to write pseudo history to reveal the relationship between social changes and people, and discuss the value of people, even human values. Readers who like science fiction literature will observe and examine human history and life according to the scientific methods and ways of thinking introduced in the book, and some of them will embark on the road of scientific research. For more than a hundred years, the development of science and technology has constantly turned science fiction into reality, further encouraging the bold creation of science fiction novelists and forming positive feedback. Science fiction dramatizes the requirements and ideals of a society with rich imagination. Although science fiction is an idea literature, few art forms can compete with science fiction in terms of deeply revealing the needs, expectations, fears, worries and troubles of an era, that is, accurately reflecting the limitations of the era. Readers can see the aspects of the times and another kind of life under the "If XXX", and thus be inspired. This inspiration can not only be the admiration for the beauty of the universe, guide the interest in science, but also be the impulse to create, and can also be a new understanding of human feelings and psychology. By reading the science fiction of a certain year, the reader can actually get a clearer social profile than that reflected by the "contemporary fiction" and non fiction inspection of that year. A very intuitive example is that when a large number of decadent literature was published in Europe during the Cold War, science fiction was talking about world war, the destruction and rebirth of mankind, the dawn of peace, the distant sky, the mechanization of human beings and the humanization of machines. By describing the possibility that the reader has not yet considered - a world of another form, a species different from ours, a form of civilization that has never existed before, and a different view of things - science fiction effectively comments on society and promotes social development, so as to enhance the reader's ability to respond to changes in the real world. Science fiction can not only enable people to prepare for the future, but also create or change ideas, so that people can create the future better. When people laugh at the failure of old science fiction predictions, they laugh not only at that time, but also at this time.
