What is Ringworld?

Ringworld is the Nebula and Hugo-Award winning the 1970 science fiction novel Larry Niven. It is considered a classic novel of the genre. In the years since the novel's release, the term "Ringworld" referred to his namesake in the novel: A huge circle -shaped colony equal to the length of the Earth's orbit. Its width was 1 million miles, 125 times wider than the country's average. Its perimeter is mentioned as 6 × 10 8 miles, because the area was about 300 million times larger than Earth. Artificial gravity was provided by rapid rotation of the circle. In the story, every planet in the Solar System was dismantled and used to construct Ringworld.

Ringworld is a perfect example of megaTRUPRUCTURE in sci -fi; An informally artificial construct exceeding a hundred kilometers in at least one dimension. Megastructures are not entirely sci -Fi - at least two already exist at the beginning of the 21st century - the Great Wall of China, at 3,947 miles (6 352 km) long and rice terrace of the Philippine Cordilleras, an agricultural complex with an area of ​​10,360Erection kilometers (4,000 square miles). In sci -fi, the word often refers to something suspended in the universe.

Starting physics numbers on the Ringworld structure has long been an interest in sci -fi geeks and extreme engineering enthusiasts. The novel states that 20 Jupiter's energy materials must be consumed to spin the ring fast enough to simulate 1 g gravity with centrifugal force. Calculations have found that this is correct. In order to prevent the ring from flying due to centrifugal force, the basic material with the tensile strength of the equality of the atomic nucleus would be required. In the novel, this material is called Scrith. The only known material with stroke equal to Scrith is neutronium that consists of neutron stars. If the neutronium could be created in a circle in some way, it would be likely to collapse to its own gravity.

Larry Niven said his ringworlD was a mediation step between the planet and the dyson sphere; The artificial ball completely closed the star. One could take hundreds of thousands of years if it could be built at all.

Most people discussing the Ringworld object consider it a fascinating thought experiment and interesting SCI -Fi. Scaled-down Ringworlds are listed in a series of computer game halo .
