Topic description:
Hard sci-fi is a branch of science fiction built strictly on real scientific laws and theories. Technological and physical plausibility matter greatly; speculation goes only as far as scientific frameworks allow. In these stories details have stakes: how a theory or device works can be central to the plot. Readers and viewers get not only adventure but a logically constructed imagined future.
