Twenty thousand years into the future, an experiment in quantum physics has had a catastrophic result, creating an enormous, rapidly expanding vacuum that devours everything it comes in contact with. Now humans must confront this deadly expansion. Tchicaya, aboard a starship trawling the border of the vacuum, has allied himself with the Yielders-- those determined to study the vacuum while allowing it to grow unchecked. But when his fiery first love, Mariama, reenters his life on the side of the Preservationists-- those working to halt and destroy the vacuum-- Tchicaya finds himself struggling with an inner turmoil he has known since childhood. However, in the center of the vacuum, something is developing that neither Tchicaya and the Yielders nor Mariama and the Preservationists could ever have imagined possible: life.

Camille is desperate to escape her home on colonized asteroid Vesta, journeying through space in a small cocoon pod covertly and precariously attached to a cargo ship. Anna is a newly appointed port director on asteroid Ceres, intrigued by the causes that have led so-called riders like Camille to show up at her post in search of asylum. Conditions on Vesta are quickly deteriorating—for one group of people in particular. The original founders agreed to split profits equally, but the Sivadier syndicate contributed intellectual property rather than more valued tangible goods. Now the rest of the populace wants payback. As Camille travels closer to Ceres, it seems ever more likely that Vesta will demand the other asteroid stop harboring its fugitives. With The Four Thousand, the Eight Hundred, acclaimed author Greg Egan offers up a stellar, novella-length example of hard science fiction, as human and involving as it is insightful and philosophical.

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."

It causes riots and religions. It has people dancing in the streets and leaping off skyscrapers. And it's all because of the impenetrable gray shield that slid into place around the solar system on the night of November 15, 2034. Some see the bubble as the revenge of an insane God. Some see it as justice. Some even see it as protection. But one thing is for certain -- now there is the universe, and the earth. And never the twain shall meet. Or so it seems. Until a bio-enhanced PI named Nick Stavrianos takes on a job for an anonymous client: find a girl named Laura who disappeared from a mental institution by the most direct possible method -- walking through the walls.

The long-awaited new novel from Greg Egan! Hugo Award-winning author Egan returns to the field with Incandescence, a new novel of hard SF. The Amalgam spans nearly the entire galaxy, and is composed of innumerable beings from a wild variety of races, some human or near it, some entirely other. The one place that they cannot go is the bulge, the bright, hot center of the galaxy. There dwell the Aloof, who for millions of years have deflected any and all attempts to communicate with or visit them. So when Rakesh is offered an opportunity to travel within their sphere, in search of a lost race, he cannot turn it down. Roi is a member of that lost race, which is not only lost to the Amalgam, but lost to itself. In their world, there is but toil, and history and science are luxuries that they can ill afford. Rakesh's journey will take him across millennia and light years. Roi's will take her across vistas of learning and discovery just as vast.

The story of a man with a vision - immortality : for those who can afford it is found in cyberspace. Permutation city is the tale of a man with a vision - how to create immortality - and how that vision becomes something way beyond his control. Encompassing the lives and struggles of an artificial life junkie desperate to save her dying mother, a billionaire banker scarred by a terrible crime, the lovers for whom, in their timeless virtual world, love is not enough - and much more - Permutation city is filled with the sense of wonder.

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.

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.

Far in the distant, post-human future, the Cater-Zimmermann community set out to refute the theory that the universe is created exclusively for mankind by cloning themselves a thousand times over and sending each copy to a different star within the galaxy. One of the copies of Cater-Zimmermann, Paolo Venetti, arrives at Orpheus; a water-world inhabited by floating mats that perform as a Turing machine.

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 that the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilisation 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 travellers will have a chance to discover the science their planet urgently needs, and bring it back in time to avert disaster.

When a detective, a new mother, is assigned to the case of a horrific triple murder, it appears to be a self-contained domestic tragedy, a terrible event but something that doesn't affect the rest of the community. But it slowly becomes clear that something much darker may be at play, something that spreads out from the scene of the crime to corrode the closest relationships of everyone it touches, in Greg Egan's The Nearest, a Tor.com Original.At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

By the end of the 30th century humanity has the capability to travel the universe, to journey beyond earth and beyond the confines of the vulnerable human frame. The descendants of centuries of scientific, cultural and physical development divide into three: fleshers — true Homo sapiens; Gleisner robots — embodying human minds within machines that interact with the physical world; and polises — supercomputers teeming with intelligent software, containing the direct copies of billions of human personalities now existing only in the virtual reality of the polis. Diaspora is the story of Yatima — a polis being created from random mutations of the Konishi polis base mind seed — and of humankind, Of an astrophysical accident that spurs the thousandfold cloning of the polises. Of the discovery of an alien race and of a kink in time that means humanity — whatever form it takes — will never again be threatened by acts of God.

Welcome to Tvibura and Tviburi, the richly imagined twin planets that stand at the center of Greg Egan’s extraordinary new novella.

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.

Hard science fiction’s grand master delivers the stunning conclusion to his Orthogonal trilogy. In a universe where the laws of physics and the speed of light are completely alien to our own, the travelers on the ship Peerless have completed a generations-long struggle to develop advanced technology in a desperate attempt to save their home world. But as tensions mount over the risks of turning the ship around and starting the long voyage home, a new complication arises: the prospect of constructing a messaging system that will give the Peerless news of its own future. While some see this as a guarantee of safety and a chance to learn of their mission’s ultimate success, others are convinced that the knowledge will be oppressive or worse—that the system could be abused. The conflict over this proposed communication system tears the travelers’ society apart, culminating in terrible violence. To save the Peerless and its mission, two rivals must travel to a world where time runs in reverse. Continuing the epic multiple generation-spanning scope of The Clockwork Rocket and The Eternal Flame, Greg Egan’s Orthogonal series has continuously pushed the boundaries of scientific fiction without ever losing track of the lives of the individuals carrying out this grand mission. The Arrows of Time brings this fascinating space opera to a close.

Investigative reporter Andrew Worth turns down a documentary on a mysterious new mental illness -- "Distress, " or acute clinical anxiety syndrome, for another assignment. He's on his way to the artifical island of Stateless, where the world's top physicists are gathering to decide on a new TOE, or Theory of Everything, to replace Einstein's outmoded legacy.Chief among the scientists is the brilliant African Nobel laureate, Violet Mosala, the focus of Worth's story, who is the subject of mysterious death threats. Worth begins his own investigation, but it takes on even more urgency when he finds that Distress, the mental plague now affecting millions, is linked somehow to the approaching "Aleph Moment" when the TOE is finalized. The countdown has begun for a disaster that will reach all the way back to the Big Bang. And beyond...
