Sci-fi writing prompts challenge you to imagine what the future could look like and explore the consequences of technology, space travel, and scientific discovery. Science fiction has always been a genre that asks big questions about humanity.

The best science fiction stories are built on a simple formula: take one thing about the world and change it, then explore what happens. A sci-fi writing prompt does exactly this by handing you that changed element.

At GhostWhoTalks, our sci-fi writing prompts range from near-future scenarios grounded in current technology to far-future space operas set across galaxies. You will find prompts about time travel paradoxes, first contact with alien civilizations, dystopian societies, and cyberpunk cities.

When approaching a sci-fi prompt, resist the urge to explain all the technology at once. The most effective technique is to show your futuristic world through the eyes of a character who takes it for granted.

Consider the human element in every prompt you choose. The technology is the setting, but the story is about people. What does your character want? How does the sci-fi element make their problem harder or more interesting?

If you are new to writing science fiction, start with a prompt that is close to the present day. Stories set five or ten years in the future require less worldbuilding and let you focus on character and plot.
