What science fiction is

A term you'll meet in literary genre.

Science fiction is the genre that imagines the consequences of science, technology, and change — extrapolating from what we know to what might be. At its best it isn't about gadgets at all; it uses the future, space, or the impossible as a lens for examining the present.

The "what if" engine

Science fiction runs on a single question: what if? What if we could live forever, travel faster than light, build a thinking machine, meet a truly alien mind? The genre takes one such premise, treats it with rigour, and follows its human consequences. The novelist Robert Heinlein and others built whole works from exactly this disciplined speculation.

Hard vs. soft

"Hard" science fiction prizes scientific plausibility — the physics has to work. "Soft" science fiction cares more about people and society, using the sciences of psychology, anthropology, and politics. Ursula K. Le Guin and Octavia Butler wrote profound soft SF; the distinction marks emphasis, not quality.

A mirror for the present

The future in science fiction is almost always a comment on now. Orwell's 1984 and Huxley's Brave New World warn about their own centuries; Le Guin's invented societies test ideas about gender and power. The estrangement of an unfamiliar world lets readers see their own assumptions from the outside.

How to read it

Identify the central "novum" — the one new thing the world adds (a technology, a discovery, a social change) — and then watch what the story claims follows from it. Science fiction's real argument is always there: in the consequences it chooses to imagine.
