Science fiction did not begin with rockets and robots. It began with a simple question asked well: what if? What if a comet grazed the earth, what if a man could stop time, what if science could raise the dead? The writers below asked those questions a century ago, and the best of their answers still land.
The twenty-two picks below built the genre. H. G. Wells wrote the template for most of modern science fiction in a few short years, Edgar Allan Poe was staging hoaxes and future-worlds before the word existed, Nathaniel Hawthorne ran early experiments with mad science, and Jack London told uneasy tales of invention gone wrong.

What Makes a Science Fiction Story Work
Good science fiction is not about gadgets. It is about what the gadget does to people, so a few things are worth watching for as you read. The strongest stories rest on one clear idea, a single what-if followed all the way down, and they earn their weight through human consequences, because the premise matters for how it changes a person, a city, or a species. They also balance rigor with restraint, making the science plausible enough to trust while the writer stops explaining before it gets dull.
H. G. Wells: The Architect of Modern Sci-Fi
Wells wrote the blueprints. Time travel, alien contact, invisibility, biotech gone wrong, most of it traces to these short stories.
The Star by H. G. Wells (1897). A rogue body enters the solar system and drags disaster across the earth as astronomers track its approach. Wells writes planetary catastrophe with cold, sweeping calm, then ends on a chilling shift in scale.
The Country of the Blind by H. G. Wells (1904). A mountaineer falls into a hidden valley whose people have been blind for generations, certain he will rule them because he can see. The proverb runs the other way here, and the ending is bleak and brilliant.
The Man Who Could Work Miracles by H. G. Wells (1898). An ordinary skeptic suddenly finds he can do anything by simply willing it. His imagination is far too small for the power, and one careless command nearly ends the world.
The New Accelerator by H. G. Wells (1901). A scientist invents a drug that speeds a person up thousands of times, so the world appears frozen around them. Two men test it and stroll through a stopped seaside afternoon, delighted and slightly appalled.
The Crystal Egg by H. G. Wells (1897). A dusty curio-shop crystal turns out to be a window onto the surface of Mars. The shopkeeper who can see through it becomes the only human watching another world watch back.
In the Abyss by H. G. Wells (1896). A man descends miles down in a steel sphere to the ocean floor and finds an intelligent civilization no one imagined. What they make of him, a god fallen from above, is the twist.
The Plattner Story by H. G. Wells (1896). A schoolteacher is blown into another dimension by an exploding green powder and returns with his body reversed, heart on the right side, as proof he really went somewhere.
The Stolen Bacillus by H. G. Wells (1894). An anarchist steals what he believes is a vial of live cholera to poison a city's water. The bacteriologist's chase across London, and the truth about the vial, make a tight comic thriller.
The Flowering of the Strange Orchid by H. G. Wells (1894). A mild collector buys an unknown orchid and nurses it to bloom. The plant, it turns out, feeds on blood, and it has decided on him.
The Diamond Maker by H. G. Wells (1894). A ragged man stops a stranger on a bridge to explain that he has learned to manufacture real diamonds, and cannot sell a single one without being taken for a thief. Genius is worthless without a way to prove it.
The Remarkable Case of Davidson's Eyes by H. G. Wells (1895). After an accident, a man goes blind to the room around him but sees, instead, a distant island on the far side of the world. The two places turn out to be strangely connected.
The Lord of the Dynamos by H. G. Wells (1894). A mistreated laborer at a London power station begins to worship the great electric dynamo as a god, and decides his cruel foreman would make a fitting sacrifice.
Edgar Allan Poe's Proto Science Fiction
Poe was writing science fiction before it had a name, mixing real physics with elaborate hoaxes and dark thought experiments.
The Facts in the Case of M. Valdemar by Edgar Allan Poe (1845). A dying man is hypnotized at the exact moment of death and held, speaking, on the threshold for months. Poe wrote it so convincingly that many first readers believed it was a real medical report.
The Unparalleled Adventure of One Hans Pfaall by Edgar Allan Poe (1835). A bankrupt bellows-mender builds a balloon and floats it all the way to the moon, with Poe piling on enough fake science to make the impossible journey feel almost documented.
The Balloon-Hoax by Edgar Allan Poe (1844). Poe published this account of the first Atlantic crossing by balloon as real news, and a stunned public bought it before the paper printed the retraction. Early science fiction as a practical joke on a whole city.
Mellonta Tauta by Edgar Allan Poe (1849). A letter written aboard a balloon in the year 2848 mocks the science and politics of Poe's own day from a thousand years in the future. One of the first stories to satirize the present by looking back from the future.
Nathaniel Hawthorne's Dangerous Science
Hawthorne got to the moral of modern science early: the danger is rarely the experiment, it is the man running it.
Rappaccini's Daughter by Nathaniel Hawthorne (1844). A scientist raises his daughter among poisonous plants until she herself is toxic to the touch. A young man who loves her tries to cure her, and the cure is deadlier than the disease.
The Artist of the Beautiful by Nathaniel Hawthorne (1844). A delicate watchmaker labors for years to build a mechanical butterfly that lives and flies. What a careless world does to his fragile creation is the real subject.
Jack London and the Machine Age
London brought a harder, more physical edge to the science story, with invention and experiment turning on their makers.
A Thousand Deaths by Jack London (1899). A castaway is rescued by his own estranged father, a scientist who proceeds to kill and revive him again and again as a laboratory experiment. The son's only escape is to out-science the father.
The Shadow and the Flash by Jack London (1903). Two brilliant rivals each crack invisibility by a different method, one perfectly black, one perfectly reflective, and their old jealousy drives the discovery to a lethal end.
The Red One by Jack London (1918). A dying naturalist in the jungles of Guadalcanal hears an unearthly sound and tracks it to a vast alien sphere worshiped by a local tribe. London's late, strange story of first contact at the edge of the world.
One Story That Saw the Robot Coming
Decades before the word robot existed, one story asked whether a machine could think, and what it might do about us.
Moxon's Master by Ambrose Bierce (1899). An inventor argues that his chess-playing machine is truly conscious. The reader learns just how right he was when the machine loses a game and reacts the way a proud, living thing would.
What These Stories Teach About Writing Science Fiction
Read enough of these and the same lessons keep surfacing, and they carry the most weight when you write your own science fiction. Build on one what-if and follow it honestly, even when the logic leads somewhere dark, and keep a person at the center, because the idea only matters through the human it changes. Give the science just enough detail to be believed and then get out of the way, and let the ending turn on a consequence rather than a gadget, because the best sci-fi twist is a truth and not a trick.

Frequently Asked Questions
Here are the most frequently asked questions about science fiction short stories.
What is a science fiction short story?
A science fiction short story builds a complete tale around a speculative idea rooted in science or technology: a new invention, a scientific discovery, contact with other worlds, or a changed future. The idea drives the plot and reveals something about people.
Where can I read these science fiction stories for free?
Every story on this list is in the public domain, so all of them are free and legal to read in full. The links here point mostly to Wikisource, and you can also find these authors on Project Gutenberg.
Who is the father of science fiction?
H. G. Wells is often called the father of science fiction, alongside Jules Verne. The short stories collected here show why: Wells wrote early, definitive versions of alien contact, time and dimension travel, invisibility, and biotechnology run amok.
What makes a good science fiction story?
One strong what-if, human consequences that make the idea matter, and just enough scientific rigor to earn the reader's trust. The gadget is never the point. What it does to people is.
How do I start writing science fiction?
Start with a single what-if and one character it affects, then follow the idea to its honest conclusion. Keep the explanation lean and the human stakes high. Reading widely in the form helps most, so work through the examples above.
