Why use lengthy exposition in science fiction?

Answer 1

Exposition is usually used to establish the setting within which the story takes place. In other types of fiction the setting is usually well known. For example, in a Western, the potential threat from "Injuns," the negative feelings of some whites ("the only good one is a dead one") , the function of the town marshal and the salloon keeper, the character of the cowboy, etc., are understood by all readers and require no explanation. In Science Fiction, the setting is less familiar or not familiar at all and must be more clearly explained. While better works integrate much of this into presentation of the story, some rely on more legnthy exposition (description/explanation by author/narrator directly to reader) to serve this function. Older works of science fiction were especially noteworthy for their extended use of exposition, both at the beginning and later, in part because more of the authors were learning to write, and in part because much of the readership were technically oriented young boys and tollerated, or even preferred, this style.

Answer 2

Long expositions in science fiction can help to establish the setting, explain complex technology or concepts, and provide important context for the story. They can help readers understand the world the author has created and immerse themselves in the narrative. However, excessive exposition can slow down the pace of the story and alienate readers who prefer a more action-driven plot.
