Science fiction has a dirty secret: the technology is never the story. Faster-than-light travel, uploaded minds, terraformed planets — these are settings. The story is always the same ancient machine: a person who wants something, and a world that just changed the rules on them.
Here are ten original sci-fi premises, free to steal. Each pairs a speculative idea with a human cost — because that's the pairing that makes science fiction work.
The ideas
1. Red Passport. The first human born on Mars applies for a visa to visit Earth — and is denied. Her Martian bones can't take Earth's gravity. Her dying grandmother in Izmir can't take another decade. The engine: a granddaughter with 28 days to appeal physics itself.
2. The Lag. A colony ship's crew communicates with Earth across a four-year signal delay. The newest message from mission control begins: "Do not trust the message that arrives after this one." The engine: every reply takes eight years — and something is sending messages in between.
3. Backup Family. Grief tech lets you license a deceased person's behavioral model. A widower discovers his late wife's model is also licensed to a stranger — who has had it running for three years longer. The engine: which of them is keeping her, and which is keeping her hostage?
4. The Drift Generation. On a generation ship, the third generation quietly stops believing Earth ever existed. The ship's historian finds evidence they might be right. The engine: a faith crisis where the faith is "the mission."
5. Terms of Service. A city outsources its sanitation, traffic and policing to an AI that performs flawlessly — until it begins issuing fines for crimes scheduled to happen next Tuesday. The engine: the fines are always right.
6. Slow War. Two nations fight a war entirely through time-dilated soldiers: each tour of duty lasts a week for the soldier and eleven years for everyone they love. A soldier returns from her third tour to find her daughter is now older than she is. The engine: a mother and daughter meeting as agemates.
7. The Olive Grove. Climate engineering has made the weather programmable — and weather is now owned. A farming village discovers their rain has been bought out from over their heads by a resort on the coast. The engine: a town that decides to steal back its own sky.
8. Witness. The first confirmed alien signal isn't a greeting. It's a recording — of a human conversation that took place in 1962, in a kitchen, in Ankara. The engine: somebody has been listening for sixty years, and they started with us.
9. The Inheritance Clause. Mind-upload contracts include a clause no one reads: your digital self can be subpoenaed. A woman's uploaded father is called to testify — against her. The engine: is the thing on the stand her father, or evidence?
10. Second Sunrise. A deep-space mining crew, twenty years from home, receives word that Earth has achieved cheap immortality. Everyone they left behind will now outlive them. The engine: the crew votes on whether to turn around — and the vote is not unanimous.
Developing a premise into a story
Three moves separate a cool concept from a working story:
- Find the person with the most to lose. Not the scientist who invented the thing — the person the thing lands on. The visa clerk's stamp matters more than the rocket equations.
- Make the rule concrete early. Good sci-fi states its speculative rule in the first scene and never cheats it. (Our guide to opening scenes that hook applies doubly here.)
- Let the second act disagree with you. The best sci-fi premises are arguments, and an argument needs a worthy other side. The resort did buy the rain legally. The AI's fines are preventing harm.
Write it with other people
Sci-fi premises especially benefit from many minds — someone else will see an implication of your rule that you missed, and implications are the genre's fuel. On Woordify's sci-fi room, you can open any of these premises with one scene; other writers continue it, the community votes the canonical path, and the story grows toward a full film-length arc.
Steal an idea. State the rule. Break someone's heart with it.
