, a young human woman who becomes Louis's lover, also join the crew. On the puppeteer home world, they are told that the expedition's goal is to investigate the Ringworld, a gigantic artificial ring, to see if it poses any threat. The Ringworld is about one million miles (1.6 million km) wide and approximately the diameter of Earth's orbit (which makes it about 584.3 million miles or 940.4 million km in circumference), encircling a sunlike star. It rotates to provide artificial gravity 99.2% as strong as Earth's from

in which they travelled to the puppeteer home world; it is orders of magnitude faster than any possessed by humans or Kzinti. When they reach the vicinity of the Ringworld, they are unable to contact anyone, and their ship, the ''Lying Bastard'', is disabled by the Ringworld's automated meteoroid-defense system. The severely damaged vessel collides with a strand of shadow-square wire and crash-lands near a huge mountain, "Fist-of-God". As the fusion drive is destroyed, they are unable to launch back into space where they could use the undamaged faster-than-light hyperdrive to return home. They set out to find a way to get the ''Lying Bastard'' off the Ringworld. Using their flycycles (similar to antigravity

s), they try to reach the rim of the ring, where they hope to find some technology that will help them. It will take them months to cross the vast distance. When Teela develops "Plateau trance" (a kind of highway hypnosis), they are forced to land. On the ground, they encounter apparently primitive human natives who live in the crumbling ruins of a once-advanced city and think that the crew are the engineers who created the ring, and whom they revere as gods.

(the misuse of certain technologies). They continue their journey, during which Nessus reveals some Puppeteer secrets: they have conducted experiments on both humans (breeding for luck via Birthright Lotteries: all of Teela's ancestors for six generations were born from winning the lottery) and Kzinti (breeding for reduced aggression via the Man-Kzin wars, which the Kzinti always lost). Speaker's outrage forces Nessus to flee and follow them from a safe distance. In a floating building over the ruins of a city, they find a map of the Ringworld and videos of its past civilization. While flying through a giant storm caused by air escaping through a hole in the Ring floor due to a meteoroid impact, Teela becomes separated from the others. While Louis and Speaker search for her, their flycycles are caught by an automated police trap designed to catch traffic offenders. They are trapped in the basement of a floating police station. Nessus enters the station to try to help them. In the station, they meet Halrloprillalar Hotrufan ("Prill"), a former crew member of a trading spaceship that collected plants and animals that couldn't adapt to the Ringworld. When her ship returned to the Ringworld the last time, they found that civilization had collapsed. The crew managed to enter the Ringworld, but some of them were killed and others suffered brain damage when the device that let them pass through the Ringworld floor failed. From her account, they learn that a mold was brought back from one of the original planets of the engineers by a spaceship like Prill's; it broke down the superconductors vital to the Ringworld civilization, dooming it. Teela reaches the police station, accompanied by her new lover, a native "hero" called Seeker who helped her survive. Based on an insight gained from studying an ancient Ringworld map, Louis comes up with a plan to get home. Teela chooses to remain on the Ringworld with Seeker. Louis, formerly skeptical about breeding for luck, now wonders if the entire mission was caused by Teela's luck, to unite her with her true love and help her mature. The party collects one end of the shadow-square wire that was snapped when the ship crashed. They travel back to their crashed ship in the floating police station, dragging the wire behind them. Louis threads it through the ship to tether it to the police station. He then takes the police station up to the summit of "Fist-of-God", the enormous mountain near their crash site. The mountain had not appeared on the Ringworld map, leading Louis to conclude that it is in fact the result of a meteoroid impact with the underside of the ring, which pushed the "mountain" up from the ring's floor and broke through. The top of the mountain, above the atmosphere, is therefore just a hole in the Ringworld floor. Louis drives the police station over the edge, dragging the ''Lying Bastard'' along with it. The Ringworld spins very quickly, so once the ship drops through the hole and clears the ring, they can use the ship's hyperdrive to get home. The book concludes with Louis and Speaker discussing returning to the Ringworld.


Reception

found ''Ringworld'' to be "excellent and entertaining ... woven together very skillfully and proceed ngat a pretty smooth pace." While praising the novel generally, he faulted Niven for relying on inconsistencies regarding evolution in his extrapolations to support his fictional premises. Sam Jordison described ''Ringworld'' as "arguably one of the most influential science fiction novels of the past 50 years.


Concepts reused

In addition to the two aliens, Niven includes a number of concepts from his other Known Space stories: * The puppeteers' General Products hulls, which are impervious to any known force except

Errors

The opening chapter of the original paperback edition of ''Ringworld'' featured Louis Wu teleporting eastward around the Earth in order to extend his birthday. Moving in this direction would, in fact, make local time later rather than earlier, so that Wu would soon arrive in the early morning of the next calendar day. Niven was "endlessly teased" about this error, which he corrected in subsequent printings to show Wu teleporting westward. In his dedication to ''The Ringworld Engineers'', Niven wrote, "If you own a first paperback edition of ''Ringworld'', it's the one with the mistakes in it. It's worth money." After the publication of ''Ringworld'', many fans identified numerous engineering problems in the Ringworld as described in the novel. One major one was that the Ringworld, being a rigid structure, was not actually in orbit around the star it encircled and would eventually drift, ultimately colliding with its sun and disintegrating. This led MIT students attending the 1971
