Editing Faster-than-light communication (section)

===Other devices===
Similar devices are present in the works of numerous others, such as [[Frank Herbert]]<ref name="star">{{cite book |last= Herbert |first= Frank |author-link= Frank Herbert |title= The Whipping Star |orig-year= 1970 |date= April 1970 |publisher= Worlds of If magazine}}</ref> and [[Philip Pullman]], who called his a ''lodestone resonator''.<ref name="amber">{{cite book |last= Pullman |first= Philip |author-link= Philip Pullman |title= The Amber Spyglass |orig-year= 2000 |edition= His Dark Materials, 3. mass pbk. |date= 2001-10-02 |publisher= [[Del Rey Books|Del Rey]] |location= New York |isbn= 0-345-41337-7 |page= [https://archive.org/details/amberspyglass00pull/page/156 156] |quote= Well, in our world there is a way of taking a common lodestone and entangling all its particles, and then splitting it in two so that both parts resonate together. |url= https://archive.org/details/amberspyglass00pull/page/156 }}</ref>

[[Anne McCaffrey]]'s ''[[Crystal Singer]]'' series posited an instantaneous communication device powered by rare "Black Crystal" from the planet Ballybran. Black Crystals cut from the same mineral deposit could be "tuned" to sympathetically vibrate with each other instantly, even when separated by interstellar distances, allowing instantaneous telephone-like voice and [[data communication]]. Similarly, in [[Gregory Keyes]]' series ''[[The Age of Unreason]]'', "aetherschreibers" use two-halves of a single "chime" to communicate, aided by scientific alchemy.<ref>{{cite book |last=Keyes|first=J. Gregory|title=The Shadows of God|date=4 March 2009|publisher=Random House LLC|isbn=9780307559609|url=https://books.google.com/books?id=V7M0bI6HqdoC&pg=PT192|quote=My aetherschreiber was lost when the Coweta captured us.}}</ref> While the speed of communication is important, so is the fact that the messages cannot be overheard except by listeners with a piece of the same original crystal.

[[Stephen R. Donaldson]], in his [[The Gap Cycle|Gap cycle]], proposed a similar system, ''Symbiotic Crystalline Resonance Transmission'', clearly ansible-type technology but very difficult to produce and limited to text messages.

In "[[With Folded Hands]]" (1947) and ''[[The Humanoids]]'' (1949), by [[Jack Williamson]], instant communication and power transfer through interstellar space is possible with ''rhodomagnetic energy''.

In [[Ivan Yefremov]]'s 1957 novel [[Andromeda (novel)|''Andromeda Nebula'']], a device for instant transfer of information and matter is made real by using "bipolar mathematics" to explore use of anti-gravitational shadow vectors through a zero field and the antispace, which enables them to make contact with the planet of Epsilon Tucanae.

In [[Edmond Hamilton]]'s ''The Star Kings'' (1949), the discovery of an unknown form of electromagnetic radiation called sub-spectrum rays moves faster than light. The fastest of these are those of the Minus-42nd Octave, which allows for real time telestereo communication with anyone within the galaxy.<ref>[https://amazingstories.com/2014/02/star-kings-future-history/ Star King's Future History – Amazing Stories].</ref>

In [[Cordwainer Smith]]'s [[Instrumentality of Mankind|Instrumentality]] novels and stories, interplanetary and [[interstellar communication]] is normally relayed from planet to planet, presumably at superluminal speed for each stage (at least between solar systems) but with a cumulative delay. For urgent communication there is the "instant message", which is effectively instantaneous but very expensive.<ref>Smith, Cordwainer. "On the Storm Planet" (February 1965), Chap. XII, pp. 148–149 in: {{cite book |editor1-last=Dozois |editor1-first=Gardner |editor1-link=Gardner Dozois |title=Modern Classic Short Novels of Science Fiction |date=28 October 2014 |publisher=[[St. Martin's Press]] |location=New York|pages=94–163|url=https://books.google.com/books?id=ub6FBAAAQBAJ&pg=PA148 |quote=The communicator was the kind they mount in planoforming ships right beside the pilot.

Casher, knowing the prices of this kind of communication, almost felt that he could see the arterial spurt of money go out of Henriada's budget as the machines reached across the galaxy, found Mizzer and came back with the answer.|isbn=9781466884472 }}</ref>

In [[Howard Tayler|Howard Taylor]]'s web comic series [[Schlock Mercenary]], superluminal communication is performed via the hypernet, a galaxy-spanning analogue to the [[Internet]]. Through the hypernet, communications and data are routed through nanoscopic wormholes, using conventional electromagnetic signals.
