Ansible

Last updated April 03, 2024

An ansible is a category of fictional devices or technology capable of near-instantaneous or faster-than-light communication. It can send and receive messages to and from a corresponding device over any distance or obstacle whatsoever with no delay, even between star systems. As a name for such a device, the word "ansible" first appeared in a 1966 novel by Ursula K. Le Guin. Since that time, the term has been broadly used in the works of numerous science fiction authors, across a variety of settings and continuities.^[1] A related term is ultrawave.^[2]^[3]

Coinage by Ursula Le Guin

Ursula K. Le Guin coined the word "ansible" in her 1966 novel Rocannon's World .^[1]^[4] The word was a contraction of "answerable", as the device would allow its users to receive answers to their messages in a reasonable amount of time, even over interstellar distances.^[5]

The ansible was the basis for creating a specific kind of interstellar civilization –one where communications between far-flung stars are instantaneous, but humans can only travel at relativistic speeds. Under these conditions, a full-fledged galactic empire is not possible, but there is a looser interstellar organization, in which several of Le Guin's protagonists are involved.

Although Le Guin invented the name "ansible" for this type of device (fleshed out with specific details in her fictional works), the broader concept of instantaneous or faster-than-light communication had previously existed in science fiction. Similar communication functions were included in a device called an interocitor in the 1952 novel This Island Earth by Raymond F. Jones, and the 1955 film based on that novel. Also in the "Dirac Communicator" which first appeared in James Blish's short story "Beep" (1954) and was later expanded into the novel The Quincunx of Time (1973).^[6] Robert A. Heinlein in Time for the Stars (1958) employed instantaneous telepathic communication between identical twin pairs over interstellar distances, and like Le Guin, provided a technical explanation based on a non-Einsteinian principle of simultaneity.

In Le Guin's works

In her subsequent works, Le Guin continued to develop the concept of the ansible:

In The Left Hand of Darkness (1969), Le Guin writes that the ansible "doesn't involve radio waves, or any form of energy. The principle it works on, the constant of simultaneity, is analogous in some ways to gravity ... One point has to be fixed, on a planet of certain mass, but the other end is portable."
In The Word for World Is Forest (1972), Le Guin explains that in order for communication to work with any pair of ansibles, at least one "must be on a large-mass body, the other can be anywhere in the cosmos".
In The Dispossessed (1974), Le Guin tells of the development of the theory leading up to the ansible.^[7]

Any ansible may be used to communicate through any other, by setting its coordinates to those of the receiving ansible. They have a limited bandwidth, which only allows for at most a few hundred characters of text to be communicated in any transaction of a dialog session, and are attached to a keyboard and small display to perform text messaging.

Use by later authors

Since Le Guin's conception of the ansible, the name of the device has been borrowed by numerous authors. While Le Guin's ansible was said to communicate "instantaneously",^[7] the name has also been adopted for devices capable of communication at finite speeds that are faster than light. David Langford publishes the science fiction fanzine and newsletter Ansible (magazine)

Orson Scott Card's works

Orson Scott Card, in his 1977 novelette and 1985 novel Ender's Game and its sequels, used the term "ansible" as an unofficial name for the Philotic Parallax Instantaneous Communicator, a machine capable of communicating across infinite distances with no time delay.^[8] In Ender's Game, Colonel Graff states that "somebody dredged the name ansible out of an old book somewhere".^[8] In an answer on the question-and-answer website Quora, Card explained why he chose to reuse the word "ansible" for an FTL communication device instead of developing a new in-universe name for one: "In an ftl universe, you have several levels. I've you can travel hyperfast, but no radio signal can outstrip your ship. Therefore you have to carry the mail with you. It's like the way things were between Europe and America before the laying of the successful transatlantic cable. But once it was laid, messages could be sent long before a ship could make the passage. That is like the ansible universe in which Ursula K. LeGuin‘s early Hainish novels. Since I needed to use exactly that rule set, why not use the word — an excellent word — which I apply in the same way we all say “robot,” an invented word that has entered the language. Thus I paid tribute to the writer from whose works I learned the word."^[9]

In the universe of the Ender's Game series, the ansible's functions involved a fictional subatomic particle, the philote.^[10] The two quarks inside a pi meson can be separated by an arbitrary distance, while remaining connected by "philotic rays".^[10] This concept is similar to quantum teleportation due to entanglement; however, in reality, quark confinement prevents quarks from being separated by any observable distance.

Card's version of the ansible was also featured in the video game Advent Rising , for which Card helped write the story, and in the movie Ender's Game , which was based on the book.^[11]

Other writers

Numerous other writers have included faster-than-light communication devices in their fictional works. Notable examples include:

Christopher Rowley, in his 1986 novel Starhammer, describes the Deep Link, an instantaneous interstellar communicator. Most commonly used for messaging, it is capable of voice and video conversations as well, although the latter only at great expense.^[12]
Vernor Vinge, in the 1988 short story "The Blabber"^[13]
Elizabeth Moon, in the 1995 novel Winning Colors^[14]
Jason Jones, in the 1995 computer game Marathon 2: Durandal ^[15]
L.A. Graf, in the 1996 Star Trek: Deep Space Nine novel Time's Enemy^[16]
The New Jedi Order, 1999, featured enemies, the Yuuzhan Vong, use organic communication devices known as villips, which can transmit over infinite distances thanks to telepathic connections formed while being harvested in groups
Philip Pullman, in the 2000 novel The Amber Spyglass , part of the His Dark Materials trilogy
Neal Asher, in his Polity series of novels including Gridlinked (2001), in which the runcible, named in homage to the ansible, is an interstellar wormhole generator/teleporter
Dan Simmons, in the 2003 novel Ilium ^[17]
Liu Cixin, in the 2008 trilogy Remembrance of Earth's Past
Kim Stanley Robinson, in the 2012 novel 2312 ^[18]
Becky Chambers, in her Wayfarer novels, including the 2014 novel The Long Way to a Small, Angry Planet , and 2016 novel A Closed and Common Orbit
L.J Cohen in the 2014 novel Derelict
Neon Yang, in the 2017 novella Waiting on a Bright Moon^[19]

<i>The Dispossessed</i> 1974 science fiction novel by Ursula K. Le Guin

The Dispossessed is a 1974 utopian science fiction novel by American writer Ursula K. Le Guin, one of her seven Hainish Cycle novels. It is one of a small number of books to win all three Hugo, Locus and Nebula Awards for Best Novel. It achieved a degree of literary recognition unusual for science fiction due to its exploration of themes such as anarchism and revolutionary societies, capitalism, utopia, individualism, and collectivism.

The Hainish Cycle consists of a number of science fiction novels and stories by Ursula K. Le Guin. It is set in a future history in which civilizations of human beings on planets orbiting a number of nearby stars, including Terra ("Earth"), are contacting each other for the first time and establishing diplomatic relations, and setting up a confederacy under the guidance of the oldest of the human worlds, peaceful Hain. In this history, human beings did not evolve on Earth but were the result of interstellar colonies planted by Hain long ago, which was followed by a long period when interstellar travel ceased. Some of the races have new genetic traits, a result of ancient Hainish experiments in genetic engineering, including people who can dream while awake, and a world of hermaphroditic people who only come into active sexuality once a month, not knowing which sex will manifest in them. In keeping with Le Guin's style, she uses varied social and environmental settings to explore the anthropological and sociological outcomes of human evolution in those diverse environments.

<i>Enders Game</i> 1985 novel by Orson Scott Card

Ender's Game is a 1985 military science fiction novel by American author Orson Scott Card. Set at an unspecified date in Earth's future, the novel presents an imperiled humankind after two conflicts with an insectoid alien species they dub "the buggers". In preparation for an anticipated third invasion, Earth's international military force recruits young children, including the novel's protagonist, Andrew "Ender" Wiggin, to be trained as elite officers. The children learn military strategy and leadership by playing increasingly difficult war games, including some in zero gravity, where Ender's tactical genius is revealed.

Galactic empires are a science fiction setting trope, in which most or all of the habitable planets in the setting's galaxy are ruled by a single centralized political entity. Galactic empires most frequently appear in works in the sub-genres of science fantasy and space opera, although they may appear in other sub-genres as well. Works featuring galactic empires may have them as the story's focus, chronicling the empire's growth and/or decline. Alternatively, they may merely serve as a backdrop against which the events of the story play out.

"The Dowry of Angyar" is a science fiction short story by American writer Ursula K. Le Guin, first published in 1964. It is the first work of the Hainish Cycle. The story is set on a fictional planet of the star Fomalhaut, and follows a highborn woman as she tries to track down a family heirloom. It was framed by commentary from ethnologists studying the intelligent life-forms of the Fomalhaut system. The story drew from Norse mythology, including the legend of the Brísingamen, and explored the concept of time dilation. "The Dowry of Angyar" drew comments for its stylistic devices, while a review praised Le Guin's writing as "crystalline prose". It was later used as the prologue to Le Guin's 1966 novel Rocannon's World. In later publications, including in the 1975 anthology The Wind's Twelve Quarters, the story was given the title "Semley's Necklace".
