Contact (Literature)

A romance written by Carl Sagan, it tells the story of our first contact with extraterrestrial intelligence... but in a manner much more realistic than the usual portrayal with UFOs and impossibly quick interstellar travel.

Ellie Arroway, a radioastronomer working in Arecibo, New Mexico, discovers a steady and clear signal coming from a point in space that corresponds to the distant star Vega. The signal is confirmed to be legitimate, and soon a worldwide effort is made to receive the message whole(due to the impossibility of monitoring the same spot in the sky as the Earth revolves) and then to decipher it, while religious and political uproar rises all around.

Was adapted into a film Contact in 1997. Not to be confused with the unrelated game Contact or the trope First Contact.

This work contains examples of:

 * Aliens Speaking English: Averted, at least in the most common sense. The idea that a different civilization, with different history and technological level, would be transmitting in binary in the same fashion as we do, though, is a very close call.
 * Aliens Steal Cable: The first signal sent to us is a repetition of the first of Earth's radio transmissions to reach space(which was what alerted them of our presence): Adolf Hitler at the overture of the Berlin Olympics. Fortunately, it's only used as a vessel for a coded message.
 * Alternative Number System: Apparently someone likes base 11.
 * Arc Words: Each chapter is named after a concept that's important to the events described in the chapter. Maybe the most important: "palimpsest" (a message written under another message in a roll of parchment).
 * Epigraph: Every chapter.
 * Faster-Than-Light Travel: An actually plausible version of this, at that.
 * First Contact: Aborded realistically. There are no little green men coming in impossibly quick metallic ships, but a radio signal just like the ones we do send into space as well.
 * First Contact Math: The reason the signal is considered a signal of intelligence is because it transmits a long series of prime numbers. As it turns out, it was only a way to attract our attention, as the message is hidden underneath it(and the really important message is hidden underneath the original message).
 * They also use prime numbers to codify images and video(each number codifies the coordinates of a black point as a product of primes).
 * A Form You Are Comfortable With: Near the end of the novel,
 * He Also Did: Carl Sagan, astronomer and famous for the scientific documentary Cosmos, as well as essays and books of scientific and skeptical nature, writing a novel might sound alien for some. Indeed, it's possible to notice common points in this book which are later repeated(or are repeated from) his other works.
 * Heroic Bastard: finds out in the very last chapter that . This subplot is completely absent from The Movie.
 * Higher-Tech Species: The First Contact aliens.
 * Portal Network
 * Precision F-Strike: Ellie tends to say "Holy Toledo!" when other people are around. After receiving the signal, she retreats briefly to her office, closes the door, and whispers "Holy shit!"
 * Precursors: The unknown aliens who built the wormhole network.
 * Religion Is Right: A subtle variation of this trope occurs at the end of the novel. Ellie discovers
 * Sufficiently Advanced Alien: The First Contact aliens, the Precursors, and  The journey is to an artificial world where the aliens are researching physical constants looking for messages written into reality itself -- a church the size of a planet. And once they return, the main character is able to find one of these messages herself. Thus, Sufficiently Advanced Science is indistinguishable from religion.
 * Technology Marches On: At one point Ellie channel-surfs and finds a station offering onetime access to a downloadable fantasy RPG game; if you liked it, you could order the full game on a floppy disk.
 * Sci-Fi Writers Have No Sense of Scale: Naturally averted. He's a scientist, after all.
