The word «science» came to us from the ancient Greek language and in translation means «the art of imagination». Fantastic is a genre in which the presence of something unreal and fantastic is allowed, but this should always be a reasonable explanation, fiction should be mundane. For example, a description of the future in which state power with the help of new inventions suppresses human feelings is fantastic, since here everything can be given an explanation, that is, give answers to questions: how this happened? Why it happened? and t.D. Often science fiction relies on science.
