''Singularity Sky'' is a science fiction novel by author Charles Stross, published in 2003. It was nominated for the Hugo Award for Best Novel in 2004.〔〔 A sequel, ''Iron Sunrise'', was published that same year. Together the two are referred to as the Eschaton novels, after a near-godlike intelligence that exists in both. The novel follows the ill-fated military campaign by a repressive state, the New Republic, to retaliate for a perceived invasion of one of its colony worlds. In actuality, the planet has been visited by the Festival, a technologically advanced alien race that rewards its hosts for "entertaining" them by granting whatever the entertainer wishes, including the Festival's own technology. This causes extensive social, economic and political disruption to the colony, which was generally limited by the New Republic to technology equivalent to that found on Earth during the Industrial Revolution. Aboard the New Republic's flagship, an engineer and intelligence operative from Earth covertly attempt to prevent the use of a forbidden technology—and fall in love along the way. Themes of the novel include transhumanism (the impact of a sudden technological singularity on a repressive society) and the need for information to be free, which inspired a proposal to give every Afghan a free mobile phone to combat the Taliban. Its narrative encompasses space opera and elements of steampunk and science fantasy. Intertwined within are social and political satire, and Stross's trademark dark humour and subtle literary and cultural allusions. Stross wrote the novel during the late 1990s, his first attempt at the form. It was not his first novel to be published, but it was the first to be originally published in book form. Its original title, ''Festival of Fools'', was changed to avoid confusion with Richard Paul Russo's ''Ship of Fools''. ==Background== ''Singularity Sky'' takes place roughly in the early 23rd century, around 150 years after an event referred to by the characters as the Singularity. Shortly after the Earth's population topped 10 billion, computing technology began reaching the point where artificial intelligence could exceed that of humans through the use of closed timelike curves to send information to its past. Suddenly, one day, 90% of the population inexplicably disappeared. Messages left behind, both on computer networks and in monuments placed on the Earth and other planets of the inner solar system carry a short statement from the apparent perpetrator of this event: Earth collapses politically and economically in the wake of this population crash; the Internet Engineering Task Force eventually assumes the mantle of the United Nations, or at least its altruistic mission and charitable functions. Anarchism replaces nation-states; in the novel the UN is described as having 900 of the planet's 15,000 polities as members, and its membership is not limited to polities. A century later, the first interstellar missions, using quantum tunnelling-based jump drives to provide effective faster-than-light travel without violating causality, are launched. One that reaches Barnard's Star finds what happened to those who disappeared from Earth: they were sent to colonise other planets via wormholes that took them back one year in time for every light-year (ly) the star was from Earth. Gradually, it is learned, these colonies were scattered across a 6,000-ly area of the galaxy, all with the same message from the Eschaton etched onto a prominent monument somewhere. There is also evidence that the Eschaton has enforced the "or else" through drastic measures, such as inducing supernovae or impact events on the civilisation that attempted to create causality-violating technology. Earth and the colonies re-establish relations and trade. Some of the latter had regained the same, or higher, technological levels due in part to the "cornucopia machines", molecular assemblers that can recreate objects in predefined patterns or duplicate others, the Eschaton left them with. Transhumanist technologies that came into being before or during the Singularity, such as cybernetic implants, anti-aging and life extension treatments, are in wide use. Spaceships use antimatter, fusion and electron-sized black holes as propulsion. Some colonies, however, rejected or restricted use of advanced technology for social, cultural or political reasons, and instead of devolving into anarchism as Earth did, have replicated politically restrictive states from Earth's history. The novel takes place on two planets of one such polity, the New Republic. Its original settlers were predominantly from Eastern Europe, where many recalled the economic dislocation that followed the fall of communism there. The victorious side in an earlier civil war destroyed the sole remaining cornucopia machine, and imposed a socially and politically repressive feudalist regime that limits most technology to a level consistent with Europe at the end of the 19th century to guarantee everyone a place in society, with accompanying Victorian social mores. Despite this, there are still those who rebel and plan uprisings, along similar lines to those that happened in the historical Eastern Europe of that era. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Singularity Sky」の詳細全文を読む スポンサード リンク
