New Releases by Greg Egan

Collected together here for the first time are twelve stories by the incomparable Greg Egan, one of the most exciting writers of science fiction working today. In these dozen glimpses into the future Egan continues to explore the essence of what it is to be human, and the nature of what - and who - we are, in stories that range from parables of contemporary human conflict and ambition to far-future tales of our immortal descendants. Return to the universe of the meta-civilisation known as the Amalgam, which Egan explored in his critically acclaimed novel Incandescence: ''Riding the Crocodile'', which recounts an epic endeavour a million years from now to bridge the divide between the Amalgam and the reclusive Aloof; ''Glory'', set in the same future, in which two archaeologists strive to decipher the artefacts of an ancient civilisation, and ''Hot Rock'', where an obscure, sunless world conceals mind-spinning technological marvels, bitter factional struggles, and a many-layered secret history. This superb collection also includes the title story, the Hugo Award-winning ''Oceanic'': a boy is inducted into a religion that becomes the centre of his life, but as an adult he must face evidence that casts a new light on his faith.

A million years from now, the galaxy is divided between the vast, cooperative meta-civilisation known as the Amalgam, and the silent occupiers of the galactic core known as the Aloof. The Aloof have long rejected all attempts by the Amalgam to enter their territory, but have permitted travellers to take a perilous ride as unencrypted data in their communications network, providing a short-cut across the galaxy''s central bulge. When Rakesh encounters a traveller, Lahl, who claims she was woken by the Aloof on such a journey and shown a meteor full of traces of DNA, he accepts her challenge to try to find the uncharted world deep in the Aloof''s territory from which the meteor originated. Roi and Zak live inside the Splinter, a world of rock that swims in a sea of light they call the Incandescence. Living on the margins of a rigidly organised society, they seek to decipher the subtle clues that can reveal the true nature of the Splinter. In fact, the Splinter is orbiting a black hole, which is about to capture a neighbouring star, wreaking havoc. As the signs of danger grow, Roi, Zak, and a growing band of recruits struggle to understand and take control of their fate. Meanwhile, Rakesh is gradually uncovering their remote history, and his search for the lost DNA world ultimately leads him to a civilisation trapped in cultural stagnation, and startling revelations about the true nature and motives of the Aloof.

A representative sampling of Hugo winner Egan''s distinctive hard science fiction drawing from previously uncollected stories.

Features five science fiction stories dealing with the abuse of mathematical or physical concepts and the dire consequences on humanity''s future.

Une belle nuit, il y a trente-trois ans, les étoiles ont disparu. La Terre et avec elle l''humanité se retrouvent isolées dans une Bulle cosmique centrée sur le soleil, placées en quarantaine. Pourquoi ? Par qui ? Les hypothèses dégénèrent en cultes religieux insolites et souvent malsains. Et dans le même temps, l''humanité a appris à vivre dans les mondes virtuels. Ou bien est-ce tout l''univers qui serait devenu virtuel ? La clé du mystère serait-elle détenue par Laura Andrews, trente-trois ans, l''âge exact de la Bulle ? Mais Laura a disparu. Et les Possibles se déchaînent. Un roman quantique, éblouissant, par la grande révélation de ces dernières années, Greg Egan, écrivain australien, dont certains prétendent, puisque personne ne l''a jamais rencontré, qu''il serait un programme informatique, le premier auteur artificiel.

For twenty thousand years, every observable phenomenon in the universe has been successfully explained by the Sarumpaet Rules: the laws governing the dynamics of the quantum graphs that underlie all the constituents of matter and the geometric structure of spacetime. Now Cass has stumbled on a set of quantum graphs that might comprise the fundamental particles of an entirely different kind of physics, and she has travelled three hundred and seventy light years to Mimosa Station, a remote experimental facility, in the hope of bringing this tantalising alternative to life. The “novo-vacuum” is predicted to begin decaying the instant it’s created, but even a short-lived, microscopic speck could shed light on the origins of the universe, and test the Sarumpaet Rules more rigorously than ever before. Cass’s experiment turns out to be more successful than anticipated: the novo-vacuum is more stable than the ordinary vacuum around it, and a region in which the new physics holds sway proceeds to expand out from Mimosa at half the speed of light. Six hundred years later, more than two thousand inhabited systems have been lost to the novo-vacuum. On the Rindler, a ship that has matched velocities with the encroaching border, people have come from throughout inhabited space to study the phenomenon. Most are Preservationists, hunting for a way to turn back the tide, but a few belong to another faction: Yielders, who believe that the challenge of adapting to survive on the far side of the border would reinvigorate a civilisation that has grown stale and insular. Tchicaya has come to the Rindler to join the Yielders, but when Mariama — a childhood friend whose example inspired him to abandon his own home world and traditions for a life of travel — arrives soon after, he is shocked to discover that she plans to help the Preservationists find a way to destroy the novo-vacuum. As a theoretical breakthrough leads to a sequence of experiments that begins to reveal the true richness of the world behind the border, tensions between the opposing factions grow. When a splinter group responds to these revelations with violent, unilateral action, Tchicaya and Mariama are forced into an uneasy alliance, and travel together through the border, balancing old and new loyalties against the fate of two incomparably different universes.

In the deep future mankind is barely distinguishable from machine intelligences, rarely embodied outside of virtual environments. It is time, using the very building blocks of time and space, to engineer the universe itself. Time to enter a new quantum realm of marvels and terrors. The new novel from one of the worlds most respected and acclaimed writers marks a dramatic move into a new arena ¿ that of the wide screen SF epic ala Baxter, Banks, Hamilton and Macleod. Novels such as this have proved to be the engine house for both the major sales and the best ideas of modern SF. That the genre¿s primary ideas man and one of its finest prose stylists should direct his energies to this sort of canvas promises much. This will be Greg Egan¿s breakout book.

Etre une copie de soi-même, est-ce continuer à être soi-même ? C''est la question que se pose Paul Durham tandis qu''il multiplie ses doubles informatiques. Et il fait une découverte bouleversante : c''est qu''un univers virtuel conçu d''une certaine façon n''a plus besoin d''un support matériel pour exister. L''univers réel peut disparaître, le virtuel poursuivra son expansion. Eternellement. Paul Durham se demande avec quels êtres peupler sa Création. La Cité des permutants est probablement le livre le plus novateur de ces dix dernières années. Greg Egan, Australien, est l''étoile qui monte au firmament de la science-fiction mondiale.

Welcome to Teranesia, the island of butterflies, where evolution has stopped making sense. Prabir Suresh lives in paradise, a nine-year-old boy with an island all his own: to name, to explore, and to populate with imaginary creatures stranger than any exotic tropical wildlife. Teranesia is his kingdom, shared only with his biologist parents and baby sister Madhusree. The evolutionary puzzle of the island’s butterflies that brought his family to the remote South Moluccas barely touches Prabir; his own life revolves around the beaches, the jungle, and the schooling and friendships made possible by the net. When civil war breaks out across Indonesia, this paradise comes to a violent end. The mystery of the butterflies remains unsolved, but nearly twenty years later reports begin to appear of strange new species of plants and animals being found throughout the region — species separated from their known cousins by recent, dramatic mutations that seem far too useful to have arisen by chance from pollution, disease, or any other random catastrophe. Madhusree is now a biology student, proud of her parents’ unacknowledged work, and with no memories of the trauma of the war to discourage her, she decides to join a multinational expedition being mounted to investigate the new phenomenon. Unable to cast off his fears for her safety, Prabir reluctantly follows her. But travel between the scattered islands is difficult, and Madhusree has covered her tracks. In the hope of finding her, Prabir joins up with an independent scientist, Martha Grant, who has come to search for both clues to the mystery and whatever commercial benefits it might bring to her sponsor. As Prabir and Martha begin to untangle the secret of Teranesia, Prabir is forced to confront his past, and to face the painful realities that have shaped his life.

Luminous is a collection of ten stories: “Chaff” “Mitochondrial Eve” “Luminous” “Mister Volition” “Cocoon” “Transition Dreams” “Silver Fire” “Reasons to Be Cheerful” “Our Lady of Chernobyl” “The Planck Dive”

In 2975, the orphan Yatima is grown from a randomly mutated digital mind seed in the conceptory of Konishi polis. Yatima explores the Coalition of Polises, the network of computers where most life in the solar system now resides, and joins a friend, Inoshiro, to borrow an abandoned robot body and meet a thriving community of “fleshers” in the enclave of Atlanta. Twenty-one years later, news arrives from a lunar observatory: gravitational waves from Lac G-1, a nearby pair of neutron stars, show that the Earth is about to be bathed in a gamma-ray flash created by the stars’ collision — an event that was not expected to take place for seven million years. Yatima and Inoshiro return to Atlanta to try to warn the fleshers, but meet suspicion and disbelief. Some lives are saved, but the Earth is ravaged. In the aftermath of the disaster, the survivors resolve to discover the cause of the neutron stars’ premature collision, and they launch a thousand polises into interstellar space in search of answers. This diaspora eventually reaches a planet subtly transformed to encode a message from an older group of travellers: a greater danger than Lac G-1 is imminent, and the only escape route leads beyond the visible universe.

Andrew Worth is a science journalist with optic nerve taps and a gut full of memory chips. Burnt out after completing a documentary on controversial developments in biotechnology, he turns down a chance to report on a baffling new mental disorder known as Distress and instead takes an assignment covering the Einstein Centenary Conference on the artificial island of Stateless. There, a young South African physicist, Violet Mosala, is expected to unveil her candidate for a Theory of Everything. But the assignment is not the tropical respite Worth was expecting. While the politics surrounding the creation of Stateless grows more turbulent, and ignorance cults stage protests against the gathering scientists, a secretive group known as the Anthrocosmologists, with some very strange ideas about the Theory of Everything, begin to enact their own agenda.

Paul Durham keeps making Copies of himself: software simulations of his own brain and body which can be run in virtual reality, albeit seventeen times more slowly than real time. He wants them to be his guinea pigs for a set of experiments about the nature of artificial intelligence, time, and causality, but they keep changing their mind and baling out on him, shutting themselves down. Maria Deluca is an Autoverse addict; she’s unemployed and running out of money, but she can’t stop wasting her time playing around with the cellular automaton known as the Autoverse, a virtual world that follows a simple set of mathematical rules as its “laws of physics”. Paul makes Maria a very strange offer: he asks her to design a seed for an entire virtual biosphere able to exist inside the Autoverse, modelled right down to the molecular level. The job will pay well, and will allow her to indulge her obsession. There has to be a catch, though, because such a seed would be useless without a simulation of the Autoverse large enough to allow the resulting biosphere to grow and flourish — a feat far beyond the capacity of all the computers in the world.
