Albert Einstein’s theory of special relativity says time is relative, and one’s perception of time varies based on how quickly one is moving. Since general relativity and special relativity are theories, their applications are less concrete than the uses for technology in some science fiction on this list. We use special relativity to explain why astronauts living in space are moving more quickly — and aging more slowly — than people on Earth. Special relativity is important to the plot of Robert A. Heinlein’s 1956 novel Time for the Stars. Heinlein also uses the Twin Paradox as a plot device.
The Twin Paradox is a thought experiment that is only made possible because of the theory of special relativity. Imagine two identical twins. One remains on Earth, while the other travels to a star six light years away using a rocket that travels at six times the speed of light. Before the traveling twin leaves Earth, both twins reset their watches to zero. When the traveling twin reaches the star, her watch says eight years have passed. When the twin on Earth reads her watch, she will find 16 years have passed by the time the traveling twin reaches the star. From the perspective of the twin on Earth, the traveling twin’s rocket takes 10 years to reach the star. The light that will show the traveling twin at the star will take an additional six years to return to Earth, making the trip to the star take 16 years. To the traveler, whose rocket moves at six times the speed of light, the star she is traveling to, which seems six light years away to her twin sister on Earth, is only 4.8 light years away. It takes another 4.8 years for light to travel from Earth to her rocket, so she perceives the trip as taking roughly eight years.
Robert A. Heinlein is respected as a gifted science fiction writer. He was named the first Science Fiction Writers Grand Master in 1974. He also pursued graduate degrees in physics and mathematics at UCLA. Because of his scientific knowledge, his explanations of special relativity and the Twin Paradox are mostly correct. He applies the theories correctly, with one minor inaccuracy. In his novel, the traveling twin and the twin on Earth are communicating in real time via intercom. Once the traveling twin is moving at the speed of light, he hears the twin on Earth as though he is speaking more slowly. By contrast, the twin on Earth hears the traveling twin as though he is speaking more quickly. In fact, each twin would only be conscious of his own perception of time.
9. The Martian Chronicles by Ray Bradbury
Concept: Colonizing Mars
In Ray Bradbury’s 1950 collection of vignettes, humans have successfully colonized Mars. Bradbury explores which impulses, noble and ignoble, humans obey regardless of which planet they’re inhabiting. As of 2019, NASA is still planning to send astronauts to Mars. The topographical features that led Bradbury and other science fiction writers to imagine it might be possible to colonize Mars by the mid-20th century, though, have been revealed to be misleading.
By 1960, astronomer Carl Sagan had discovered that Mars is consistently freezing due to its lack of atmosphere, and the canals on Mars were not, as had previously been hypothesized, former waterways.
8. Jurassic Park by Michael Crichton
Concept: Reanimating Dinosaurs
Unlike the saddled dinosaurs calmly coexisting with humans in the Creation Museum’s exhibits, the destructive dinosaurs in Michael Crichton’s 1990 novel are a cautionary tale for humans. A course of action made possible by scientific advancement isn’t necessarily a wise one. However, despite the intricately detailed scientific plot of the novel, resurrecting dinosaurs isn’t possible.
The science of paleontology dates from the 19th century, and dinosaur footprints and fossils have consistently been recognized as historically important. To resurrect dinosaurs, though, paleontologists would need viable dinosaur DNA in order to reassemble dinosaurs’ genetic codes. Dinosaurs dominated the Earth roughly 66 million years ago. Even if their DNA was found, it would be too decayed to be useful in reassembling a genetic code. That’s good news for anyone getting tired of holding onto their butt.
7. Frankenstein by Mary Shelley
Concept: Reanimating Humans
Defibrillators can be used to revive someone who has gone into sudden cardiac arrest. However, it’s impossible to revive someone who has already been hanged, like the scientist Victor Frankenstein does in Mary Shelley’s 1818 novel. During the 19th century, there was scientific research that seemed to support the possibility that corpses could be revived through the use of electricity. In 1781, a surgeon, Luigi Galvani, dissected a frog while standing near a static electricity machine. When an assistant touched a nerve in the frog’s leg with a scalpel, the frog’s leg spasmed. Galvani built a bronze and iron arc, and he attached the frog’s leg and the static electricity machine to it. The frog’s leg twitched whenever it touched the metal. Galvani formed a hypothesis: he believed the frog possessed what Galvani called animal electricity. The bimetallic arc conducted the animal electricity to the frog’s nerve, making its leg twitch. The plot of Shelley’s novel is an exploration of what might be possible if humans, too, possessed animal electricity.
After reading Galvani’s work, physicist Alessandro Volta replicated Galvani’s experiment. He observed the same result, but he reached a very different conclusion. His hypothesis, which we now know to be accurate, was that the metal was acting as a conductor for the electric current from the static electricity machine. When the current touched the frog’s leg, the frog’s leg twitched.
6. Never Let You Go by Kazuo Ishiguro
Concept: Human Cloning
Jodi Picoult’s 2003 book My Sister’s Keeper explores the question of whether it’s morally defensible to expect one sibling to become an organ donor for another. In Kazuo Ishiguro’s 2005 novel, organ donation is a social requirement. Human clones are created solely to become organ donors. There are many science fiction novels featuring human clones. While the question of how humans determine quality of life will always be a valid one, human cloning isn’t currently possible. Further, there is no way to guarantee that a clone will be as healthy as the animal from whose cells the clone was created.
In 1996, Dolly, a sheep, became the first successfully cloned mammal. The average lifespan of a sheep is 12 years, but Dolly was euthanized in 2002. At six-and-a-half years old, she had already developed a progressive lung disease. She also had shorter telomeres than other sheep of a comparable age. Telomeres are pieces of DNA that protect the ends of chromosomes. Since telomeres shorten as cells divide, they are considered an indication of an animal’s age. Based on Dolly’s lung disease and the length of her telomeres, scientists speculate that she was actually born six years old, the same age as that of the sheep from which she was cloned.
5. Babylon Babies by Maurice Dantec
Concept: Designer Babies
In Maurice Dantec’s 1999 novel, a woman is carrying genetically modified twins whose birth might forever change the human race. Unlike most of the scientific advancements on this list, this one isn’t currently impossible. In 2018, Chinese researcher Jiankui He created the first babies with artificially increased resistance to HIV. Afterward, the embryos were implanted in the mother’s uterus, and the babies were born healthy.
Technically, these weren’t designer babies, because their parents weren’t selecting particular genes. However, the same gene editing techniques could be used to create designer babies. Gene editing in embryos is permitted in Japan, the United Kingdom, the United States, China, and Sweden. Gene editing is scientifically possible, but there’s not international consensus regarding whether it’s ethical. Consistent gene editing could allow certain countries to practice genocide or produce physically and intellectually enhanced soldiers that would give them an advantage during international conflicts.
4. The Dispossessed by Ursula K. Le Guin
Ursula K. Le Guin’s 1979 novel The Dispossessed isn’t the only science fiction novel depicting a utopian future for humankind. Though no author who has imagined the future as a utopia is right (so far), Le Guin’s utopia is unique for two reasons. First, her world has an anarchic planet, Anarres, that’s rich in resources. It’s a colony of an arid planet, Urras. Even in a utopia, inhabitants of Anarres are deprived of their own natural resources. Second, the novel’s protagonist, Shevek, fares better than his real world model. Shevek was modeled on a family friend of Le Guin’s, J. Robert Oppenheimer.
Shevek makes the citizens of Anarres question both the limits of their personal autonomy and the consequences of exercising it. By contrast, Oppenheimer’s expertise made the first atomic explosion possible in 1945. Unfortunately, he was stripped of his job title, chairman of the General Advisory Committee of the Atomic Energy Commission, when he opposed the United States’ development of a hydrogen bomb. Asking the American government to critique its own use of personal autonomy cost Oppenheimer his professional reputation.
3. The Time Machine by H.G. Wells
Concept: Time Travel
H.G. Wells’ 1895 novella isn’t the only story involving time travel. However, Wells popularized the idea that humans could invent a machine that makes time travel possible. Technically, time travel exists. As previously mentioned, Einstein’s theory of special relativity says time is relative, and one’s perception of time varies based on how quickly one is moving. Astronauts living in space are moving more quickly than people on Earth. Therefore, an astronaut living in space for a year will age slightly less than people who are living on Earth during that year.
The Large Hadron Collider moves protons at almost the speed of light, essentially propelling them into the future. The kind of time travel that Wells writes about — the kind that’s controlled by humans and measured based on a Western European perception of time — isn’t possible. In 2015, Ali Razeghi, the managing director of Iran’s Center for Strategic Inventions, claimed he had invented a machine that could accurately predict five to eight years into a person’s future. His claim was debunked when he declined to release the design for his time machine.
2. The Xenu Files by L. Ron HubbarL.Rond
Concept: The Origin Of Humanity
Unlike most of the entries on this list, The Xenu Files isn’t a novel. L. Ron Hubbard was a writer of popular science fiction short stories, but he’s most famous for founding the Church of Scientology. Scientologists pay a minimum of a quarter of a million dollars to audit Scientology courses. Once they reach the level of Operating Thetan 3, they are permitted to read the religion’s origin myth. According to the 2015 HBO documentary Going Clear: Scientology and the Prison of Belief, the origin myth, which was handwritten between 1966 and 1967, is stored at the church’s Advanced Organization Building.
According to Hubbard, Xenu, the dictator of the Galactic Federation, needed to solve his planet’s overpopulation problem. He sent his own subjects to Earth, then called Teegeeack. There, they were strapped to atomic bombs and hurled into volcanoes. The spirits of Xenu’s subjects, called Thetans, cling to contemporary humans. The only way to rid oneself of Thetans is through the Scientologists’ practice of auditing. In auditing, someone talks about events from his or her previous lives while an auditor reads an e-meter (a lie detector). The person’s truthfulness, as determined by the auditor, shows how susceptible the person is to Thetans.
If these religious practices seem like they belong in a science fiction novel, perhaps that’s because science fiction readers were the original intended audience for Hubbard’s ideas. After failing to convince doctors, psychologists, and explorers to integrate his ideas into their professional practices, Hubbard appealed to the science fiction readers who were fans of his work. He and his editor, John W. Campbell, Jr., developed the system of dianetics, a term used to describe the methodology of Scientology. Hubbard’s first article about dianetics appeared in a 1950 issue of the magazine Astounding. Campbell, who owned the magazine, primarily published science fiction short stories, including Hubbard’s. Later, Hubbard used one of his science fiction short stories, “Masters of Sleep,” as a prolonged advertisement for dianetics. In his 2012 post for The Village Voice, Tony Ortega says Scientologists might be more susceptible to Hubbard’s origin story in The Xenu Files because many of them have vividly experienced past lives during auditing. For Hubbard’s early readers, the process was much simpler. They encountered information about dianetics in the same magazine that had published Hubbard’s science fiction.
1. The Blazing World by Margaret Cavendish, Duchess of Newcastle
Concept: The Future
Margaret Cavendish, Duchess of Newcastle, isn’t noteworthy because her book contains prescient predictions. The North Pole isn’t a portal to another planet. We haven’t discovered a planet that we can verify is lit by the brightest stars ever created. No human has been transported to another planet, then declared war against her own home planet (unless alien victors have compromised our collective memory of the event).
No, Cavendish isn’t noteworthy because of how she envisioned the future. She’s noteworthy because of when she did it. Written in 1666, The Blazing World is widely regarded as the first science fiction novel. A respected poet, playwright, biographer, and essayist in her own time, Cavendish also created a genre. As Bronwyn Lovell says in her 2016 article for The Conversation, “Science Fiction’s Woman Problem,” science fiction is still a male-dominated genre. Still, Cavendish ensured a future for female writers by creating a space for them.
