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.

Seth is a surveyor, along with his friend Theo, a leech-like creature running through his skull who tells Seth what lies to his left and right. Theo, in turn, relies on Seth for mobility, and for ordinary vision looking forwards and backwards. Like everyone else in their world, they are symbionts, depending on each other to survive. In the universe containing Seth''s world, light cannot travel in all directions: there is a “dark cone” to the north and south. Seth can only face to the east (or the west, if he tips his head backwards). If he starts to turn to the north or south, his body stretches out across the landscape, and to rotate as far as north-north-east is every bit as impossible as accelerating to the speed of light. Every living thing in Seth’s world is in a state of perpetual migration as they follow the sun’s shifting orbit and the narrow habitable zone it creates. Cities are being constantly disassembled at one edge and rebuilt at the other, with surveyors mapping safe routes ahead. But when Seth and Theo join an expedition to the edge of the habitable zone, they discover a terrifying threat: a fissure in the surface of the world, so deep and wide that no one can perceive its limits. As the habitable zone continues to move, the migration will soon be blocked by this unbridgeable void, and the expedition has only one option to save its city from annihilation: descend into the unknown.

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”

Greg Egan''s Perihelion Summer is a story of people struggling to adapt to a suddenly alien environment, and the friendships and alliances they forge as they try to find their way in a world where the old maps have lost their meaning. Taraxippus is coming: a black hole one tenth the mass of the sun is about to enter the solar system. Matt and his friends are taking no chances. They board a mobile aquaculture rig, the Mandjet, self-sustaining in food, power and fresh water, and decide to sit out the encounter off-shore. As Taraxippus draws nearer, new observations throw the original predictions for its trajectory into doubt, and by the time it leaves the solar system, the conditions of life across the globe will be changed forever. Praise for Perihelion Summer "Egan here doubles down on climate change with his typically rigorous exploration of a cosmic accident''s effect on Earth and all its people. His characters are sharp and funny and their courageous response to the massive challenge they face works as a spur to cause us to think—why couldn''t we do as well with our own great challenge? This is what the best science fiction can do that no other genre can, and we need it now more than ever. Bravo!" — Kim Stanley Robinson At the Publisher''s request, this title is being sold without Digital Rights Management Software (DRM) applied.

Greg Egan is arguably Australia''s greatest living science fiction writer. In a career spanning more than thirty years, he has produced a steady stream of novels and stories that address a wide range of scientific and philosophical concerns: artificial intelligence, higher mathematics, science vs religion, the nature of consciousness, and the impact of technology on the human personality. All these ideas and more find their way into this generous and illuminating collection, the clear product of a man who is both a master storyteller and a rigorous, exploratory thinker. The Best of Greg Egan contains twenty stories and novellas arranged in chronological order, and each of them is a brilliantly conceived, painstakingly developed gem. The book opens with "Learning to be Me," about a society in which the organic human brain can be replaced by a miraculous piece of technology called "the jewel," a "mock brain" that confers, among other things, a kind of immortality on its recipients. "Bit Players""€"the opening movement in a trio of tales that continues with "3-adica" and "Instantiation""€"posits a world in which cheaply generated software beings are exploited for the basest commercial purposes. (Other sets of interconnected stories"€"all of them reprinted here"€"include the mathematically-themed "Luminous" and "Dark Integers," and a pair of stories centered on the complex marriage of a physicist and a mathematician: "Singleton" and "Oracle.") "Reasons to be Cheerful," concerns a young boy whose brain tumor has an unexpected effect on his life, moods, and view of the world. "Axiomatic" tells the story of a society in which "implants" can be used to alter the human personality, with potentially lethal results. And the Hugo Award-winning novella "Oceanic" is a powerful account of a boy whose deeply held religious beliefs are undermined by what he comes to learn about the laws of the physical world. This book really does represent the best of Greg Egan.

In Yalda''s universe, light has no universal speed and its creation generates energy. On Yalda''s world, plants make food by emitting their own light into the dark night sky. As a child, Yalda witnesses one of a series of strange meteors, the Hurtlers, that are entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent danger — and the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilization has yet achieved! Only one solution seems tenable: if a spacecraft can be sent on a journey at sufficiently high speed, its trip will last many generations for those on board, but it will return after just a few years have passed at home. The travelers will have a chance to discover the science their planet urgently needs, and bring it back in time to avert disaster.

Immortality, but at what price, in what form, and how could you be you?

But if you could carry on, if you could make choices about who you would be forever, how much of your past would you bring with you? Would you be tempted to maybe...edit? Adam isn’t all that he used to be, but he wants to be. At the Publisher''s request, this title is being sold without Digital Rights Management Software (DRM) applied.

“Taut, suspenseful, darkly powerful . . . Egan is on his way, and with considerable velocity!” —Gardener Dozois, editor, The Year''s Best SF In 2034, the stars went out. Riots and religions break out after an unknown agency surrounds the solar system with an impenetrable barrier, now leaving the universe in darkness. While some see this act as revenge from God, others see it as protection. The only thing known is that for now and forever, Earth and the universe shall never be connected again. Or so it seems. In 2067, PI Nick Stavrianos is hired to investigate the disappearance of Laura, a mentally disabled woman. The trail leads him to the Republic of New Hong Kong, where an organization known as the Ensemble has uncovered Laura’s secret and the only possible way she could have escaped from the institution: her ability to walk through walls. It’s up to Nick not only to find out what the Ensemble plans to do with Laura, but also—if he can—to get her before her powers transform the world. Will it be for good or bad? That’s the question Nick has to answer.

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.

Set in a near future Iran (where the theocracy has been overthrown, but where Muslim religion still dominates the culture), an Arab/Muslim focused MMORG gaming companies cutting edge AI software might hold the key achieving "uploaded consciousness." Martin is an Australian journalist who covered uprising and overthrow of the Iranian theocracy, and has since “gone native” with a Iranian wife and child. As tragedy strikes his multi-cultural family, Martin struggles to maintain his place in his adapted culture, and to provide for his child. Zendigi explores what it means to be human, and the lengths one will go to in order to provide for ones children. This emotional roller coaster explores a non-Western-European near future that both challenges ideas of global mono-culture and emphasizes the humanity we all share.

Nick Stavrianos avait huit ans quand les étoiles se sont éteintes – le 5 novembre 2034, il y a trente ans. Depuis, le Système solaire est confiné au sein d’une sphère titanesque le coupant du reste de l’univers : la Bulle. Après la sidération initiale, l’humanité, résiliente, a repris sa marche en avant malgré l’incommensurable artefact. Et si l’astronomie n’est plus désormais qu’un souvenir, la science a connu d’énormes avancées du côté des implants cérébraux. Aujourd’hui détective privé, Nick Stavrianos est missionné pour découvrir comment une femme, plongée dans un coma végétatif depuis des décennies, est parvenue à quitter sa chambre d’hôpital, fermée et surveillée, avant d’y revenir. Une énigme dont la réponse semble se trouver au cœur des rues sombres de la Nouvelle Hong Kong, enclave australienne devenue le paradis des entreprises de biotechs. C’est alors que Stavrianos est enlevé par l’Ensemble, une organisation dont il découvre bientôt qu’elle mène des recherches destinées à élucider le plus singulier des mystères, celui de la Bulle... et que lui-même pourrait bien avoir un rôle à jouer dans tout cela.

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.

Roi and Zak live inside the Splinter, a world of rock that swims in a sea of light they call the Incandescence. The Splinter is orbiting a black hole, which is about to capture a neighbouring star and wreak havoc. As danger grows, Roi, Zak and a band of recruits struggle to understand their world and take control of their fate.

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.

Greg Egan’s The Clockwork Rocket introduced readers to an exotic universe where the laws of physics are very different from our own, where the speed of light varies in ways Einstein would never allow, and where intelligent life has evolved in unique and fascinating ways. Now Egan continues his epic tale of alien beings embarked on a desperate voyage to save their world . . . . The generation ship Peerless is in search of advanced technology capable of sparing their home planet from imminent destruction. In theory, the ship is traveling fast enough that it can traverse the cosmos for generations–and still return home only a few years after they departed. But a critical fuel shortage threatens to cut their urgent voyage short, even as a population explosion stretches the ship’s life-support capacity to its limits. When the astronomer Tamara discovers the Object, a meteor whose trajectory will bring it within range of the Peerless, she sees a risky solution to the fuel crisis. Meanwhile, the biologist Carlo searches for a better way to control fertility, despite the traditions and prejudices of their society. As the scientists clash with the ship’s leaders, they find themselves caught up in two equally dangerous revolutions: one in the sexual roles of their species, the other in their very understanding of the nature of matter and energy. The Eternal Flame lights up the mind with dazzling new frontiers of physics and biology, as only Greg Egan could imagine them.

First published in Asimov''s Science Fiction, December 2015.

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.
