Writing science fiction: the core questions
Science fiction is the literature of consequences — of asking 'what if' and following the implications wherever they lead. The best SF prompts are the ones with built-in consequences: not just a technology or a world-state, but a situation where something has changed and the story is about what that change means for people.
The prompts here span three registers, which correspond roughly to different reading experiences. Intimate near-future fiction stays close to human scale — one person, one changed circumstance, maximum emotional stakes. Space opera goes big — galactic conflicts, alien civilisations, epic scope. Hard SF earns its premises through scientific rigour.
The speculative element and character
The most common mistake in SF is making the speculative element the subject of the story rather than the context for a human story. The technology or the alien world or the changed future is the setting — what happens inside that setting to characters the reader cares about is the story.
Use the world-building and technology prompts to construct your setting, then use the character prompts to find the person whose story this is. The intersection of a specific person and a specific world is where science fiction comes alive.
