Start the clock
Pick a sprint, press start and keep going until it stops. Momentum beats polish on a first draft.
Make it yours
Three ways to take this prompt somewhere nobody else will.
- Shrink the stakes to one family, one street, one night.
- Choose one ordinary object and show how this world changed it.
- Start in the middle of the strangest moment, and explain nothing for a page.
Writing science fiction
Change one thing about the world. Follow it all the way.
Science fiction asks what happens to people when science, technology or contact with something new changes the rules. The spaceships are optional; the question is the point. The best of it says as much about today as it does about the future.
What readers expect
- An idea that drives the plot
- Technology or science with consequences
- Futures, other worlds or alternate presents
- Big questions about being human
A tip before you start
Show how your big change reshapes ordinary life: what people eat, fear and joke about. Scenery alone isn't world-building.
