Hard Science Fiction: 16 Examples of Hard Science Fiction

Hard science fiction is a subgenre of science fiction writing that emphasizes scientific accuracy and precise technical detail as part of its world-building. When these science fiction stories touch on real-world topics like space travel, earth science, computer advancements, and artificial intelligence, they do so with an eye toward accuracy. Hard science fiction also goes by shortened names like “hard sci-fi” and “hard SF.” Prominent awards in the hard science fiction space include the Hugo Award, the Arthur C. Clarke Award, the Nebula Award, and the Jupiter Award.

Hard sci-fi contrasts with another type of science fiction writing that can be called soft science fiction. Soft sci-fi novels and movies deal with topics that do not comport with science as we understand it. For instance, the recreation of dinosaurs in Jurassic Park and its sequels does not fully overlap with scientific reality, although the book's explanation of DNA technology is largely accurate. Other scientifically unfeasible topics like time travel or faster-than-light spaceships similarly qualify a book as soft sci-fi.

There is no shortage of science fiction novels, short stories, movies, and TV shows that lean into hard science as part of their world-building. Explore some of the influential hard science fiction books of the past few decades.

1. 1. Foundation by Isaac Asimov (1951): This book, which kicked off a long series by Asimov, takes place in a distant future but is anchored by concepts in real-world mathematics, holographs, and psychology.
2. 2. The Sentinel by Arthur C. Clarke (1951): Clarke adapted his short story into the Stanley Kubrick-directed cinematic space opera 2001: A Space Odyssey. Between the initial short story and the movie, Clarke deals with topics of evolution, space travel, starships, artificial intelligence, and the first contact with alien life forms.
3. 3. Mission of Gravity by Hal Clement (1953): This early standard of hard science fiction novels takes place on a disk-shaped planet called Mesklin where human life cannot survive, but human-made probes can encounter aliens. As Clement describes this alien new world, he grounds his science in proven truths about chemistry and physics.
4. 4. The Andromeda Strain by Michael Crichton (1969): Crichton is best known for Jurassic Park, but in his first book, he tackled the subject of pandemic viruses.
5. 5. Tau Zero by Poul Anderson (1970): This hard science fiction novel is a thrill ride in both the figurative and literal sense, as it imagines a near-light-speed vehicle that careens out of control. While most physicists strongly doubt a future where humans could travel anywhere near the speed of light, Anderson does anchor a great deal of the novel in real-world physics.
6. 6. Ringworld by Larry Niven (1973): Niven's novel is about aliens and massive artificial worlds, but it is based on the hard science of Newtonian physics and Mendelian biology.
7. 7. Rendezvous with Rama by Arthur C. Clarke (1973): Clarke followed up his work on 2001: A Space Odyssey by penning this tale where a strange spaceship called Rama enters the solar system. The book is packed with scientifically accurate descriptions of mechanics and astrophysics.
8. 8. Dragon's Egg by Robert L. Forward (1980): This hard sci-fi book drew rave reviews from genre masters Isaac Asimov and Arthur C. Clarke for its tale of neutron stars and extraterrestrial life.
9. 9. Neuromancer by William Gibson (1984): Gibson’s dystopian novel, which bears some resemblance to Blade Runner (which came out two years prior), deals with computer science cyberpunk culture and the rise of artificial intelligence.
10. 10. Red Mars by Kim Stanley Robinson (1992): This novel, which kicks off Robinson's Mars trilogy, deals with the colonization of Mars in a world where Earth has become uninhabitable. Robinson starts with a foundation of real-world astrophysics and geopolitics and then builds from there.
11. 11. A Fire Upon the Deep by Vernor Vinge (1992): This dystopian novel about future wars with alien races bases its science on real-life military technology, artificial intelligence, astrophysics, and cognitive science.
12. 12. Starfish by Peter Watts (1999): This hard science fiction novel takes place under the sea. It deals with marine biology and bioengineering but also psychology and mental illness, topics that set it apart from many other hard sci-fi works.
13. 13. Revelation Space by Alastair Reynolds (2000): Reynolds holds a Ph.D. in astronomy and he uses it to great effect in this interstellar thriller that combines the quiet dread of Arthur C. Clarke with the astronomical wonder of Carl Sagan.
14. 14. Schild's Ladder by Greg Egan (2002): Egan bases this novel on the work of real-life mathematician Alfred Schild and his contributions to differential geometry.
15. 15. The Three-Body Problem by Cixin Liu (2008): This novel by sci-fi author Cixin Liu takes its title from a real concept in orbital mechanics. It imagines a near future where the human race awaits an interstellar invasion from beyond our solar system. Its characters discover a planet that belongs to three different suns, and while this may not be scientifically possible, it is still grounded in elements of real-world physics.
16. 16. The Martian by Andy Weir (2012): Weir's debut novel, which was later the basis of a Hollywood blockbuster, involves an astronaut stranded on Mars. His survival techniques—and the techniques of his earthbound comrades trying to rescue him—are grounded in real-world scientific facts and discoveries.
