It pushed Earth through the greatest technological evolution ever known, while warning that time travel is forbidden, and transgressors will be eliminated.Distant descendants of this ultra high-tech Earth live in parochial simplicity on the far-flung worlds of the New Republic. Their way of life is threatened by the arrival of an alien information plague known as the Festival. As forbidden technologies are literally dropped from the sky, suppressed political factions descend into revolutionary turmoil.A battle fleet is sent from Earth to destroy the Festival, but Spaceship engineer Martin Springfield and U.N. diplomat Rachel Mansour have been assigned rather different tasks. Their orders are to diffuse the crisis or to sabotage the New Republic's war-fleet, whatever the cost, before the Eschaton takes hostile action on a galactic scale.

    Not hiding, not turned black, but gone. On September 28th, Edward Shaw, a geologist working in Death valley, finds a mysterious new cinder cone in very well-mapped area As more unexplained phenomena spring up around the globeL: a granite mountain appearing in Australia, sounds emanating from the Earth's core, flashes of light among the asteroids, it becomes clear to some that the end is approaching, and there is nothing that can be done. In The Forge of God, award-winning author Greg Bear describes the final days of the world on both a massive, scientific scale and in the everyday, emotional context of individual human lives. Facing the destruction of all they know, some people turn to God, others to their families, and a few turn to saviors promising escape from a planet tearing itself apart. Will they make it in time? And who gets left behind to experience the last moments of beauty and chaos on Earth?

    The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!

    Gerald Livingston is an orbital garbage collector. For a hundred years, people have been abandoning things in space, and someone has to clean it up. But there’s something spinning a little bit higher than he expects, something that isn’t on the decades’ old orbital maps. An hour after he grabs it and brings it in, rumors fill Earth’s infomesh about an “alien artifact.” Thrown into the maelstrom of worldwide shared experience, the Artifact is a game-changer. A message in a bottle; an alien capsule that wants to communicate. The world reacts as humans always do: with fear and hope and selfishness and love and violence. And insatiable curiosity.

    In this first collaboration by science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths…and it's on a direct path heading for the same system as the human ship.A landing party is sent to investigate the Bowl, but when the explorers are separated--one group captured by the gigantic structure's alien inhabitants, the other pursued across its strange and dangerous landscape--the mystery of the Bowl's origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.

    Since the ringed planet carries no life, scientists deduce the mysterious ship to be a visitor from another star.The world's frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteriods. Now the conquerors are descending on the American heartland, demanding servile surrender--or death for all humans.

    They can't contact the aliens in any way or understand their language. All they can do is watch.Then, without warning, a military cordon is imposed on the Blind Lake site. All communication with the outside world is cut off. Food and other vital supplies are delivered by remote control. No one knows why.The scientists, nevertheless, go on with their research. Among them are Nerissa Iverson and the man she recently divorced, Raymond Scutter. They continue to work together despite the difficult conditions and the bitterness between them. Ray believes their efforts are doomed; that culture is arbitrary, and the aliens will forever be an enigma.Nerissa believes there is a commonality of sentient thought, and that our failure to understand is our own ignorance, not a fact of nature. The behavior of the alien she has been tracking seems to be developing an elusive narrative logic--and she comes to feel that the alien is somehow, impossibly, aware of the project's observers.But her time is running out. Ray is turning hostile, stalking her. The military cordon is tightening. Understanding had better come soon...

    Their charter was for a Class III uninhabited planet, which Zarathustra was, and it meant they owned the planet lock stock and barrel. They exploited it, developed it and reaped the huge profits from it without interference from the Colonial Government. Then Jack Holloway, a sunstone prospector, appeared on the scene with his family of Fuzzies and the passionate conviction that they were not cute animals but little people.

    Humanity has made it to the stars. Fassin Taak, a Slow Seer at the Court of the Nasqueron Dwellers, will be fortunate if he makes it to the end of the year. The Nasqueron Dwellers inhabit a gas giant on the outskirts of the galaxy, in a system awaiting its wormhole connection to the rest of civilization. In the meantime, they are dismissed as decadents living in a state of highly developed barbarism, hoarding data without order, hunting their own young & fighting pointless formal wars. Seconded to a military-religious order he's barely heard of—part of the baroque hierarchy of the Mercatoria, the latest galactic hegemony— Taak has to travel again amongst the Dwellers. He is in search of a secret hidden for half a billion years. But with each day that passes a war draws closer—a war threatening to overwhelm everything & everyone he's ever known.

    A Fire upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale.Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence.Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle. A rescue mission, not entirely composed of humans, must rescue the children-and a secret that may save the rest of interstellar civilization.

    On the remote planet End of Nothing, a colony of advanced robots has established project Vatican-17: the building of an infallible computerized pope whose accumulated wisdom will eventually create a truly universal religion. Gathering data for the omnivorous Pope are the Listeners, humans with ESP whose agile minds probe thru time & space. Also hanging about, on the fringes of the utopian settlement, is reclusive, anachronistic Thomas Decker & his invisible companion, Whisperer, a childlike alien of awesome latent powers. Best of all in this cast of charmers are some wonderfully Simakian robots: a beguilingly crusty electronic Pope & his splendidly idiosyncratic robot Cardinals. A lovely place--but then Listener Mary appears to have discovered Heaven (literally); the resulting rancorous dispute (Decker is murdered by a robot, there's a movement to canonize the now-insane Mary) threatens to tear Vatican-17 apart; & the conclusion--involving some secretive, puissant autochthones, trips to weird worlds, a Decker clone & a trio of peevish, megalomaniac aliens--is carried thru with just the right blend of wackiness & humility. Thoroughly enjoyable: one of the best ever from an sf grandmaster whose form has been decidedly variable in recent years.--Kirkus

    Bella Lind and the crew of her nuclearpowered ship, the Rockhopper, push ice. They mine comets. But when Janus, one of Saturn's ice moons, inexplicably leaves its natural orbit and heads out of the solar system at high speed, Bella is ordered to shadow it for the few vital days before it falls forever out of reach. In accepting this mission she sets her ship and her crew on a collision course with destiny-for Janus has many surprises in store, and not all of them are welcome...

    A spaceship from Earth accidentally crossed through a hole in space-time to a universe where the force of gravity is one billion times as strong as the gravity we know. Somehow the crew survived, aided by the fact that they emerged into a cloud of gas surrounding a black hole, which provided a breathable atmosphere. Five hundred years later, their descendants still struggle for existence, divided into two main groups. The Miners live on the Belt, a ramshackle ring of dwellings orbiting the core of a dead star, which they excavate for raw materials. These can be traded for food from the Raft, a structure built from the wreckage of the ship, on which a small group of scientists preserve the ancient knowledge which makes survival possible. Rees is a Miner whose curiosity about his world makes him stow away on a flying tree—just one of the many strange local lifeforms—carrying trade between the Belt and the Raft.

    This remote world is mostly ocean, and it is a rare visitor who ventures beyond the safety of the island Dome. Outside it, only the native Hoopers dare risk the voracious appetites of the planet's wildlife. But somewhere out there is Spatterjay Hoop -- and Keech will not rest until he brings this legendary renegade to justice for hideous crimes committed centuries ago during the Prador Wars.While Keech is discovering that Hoop is now a monster -- his body and head living apart from each other -- Janer is bewildered by a place where the native inhabitants just will not die and angry when he finally learns the Hive mind's intentions for him. Meanwhile, Erlin thinks she has plenty of time to find the answers she seeks, but could not be more wrong. For one of the most brutal of the alien Prador is about to pay the planet a surreptitious visit, intent on exterminating all remaining witnesses to his wartime atrocities. As the visitors' paths converge, major hell is about to erupt in a chaotic waterscape where minor hell is already a remorseless fact of everyday life . . . and death.

    Sarah Halifax decoded the first-ever radio transmission received from aliens. Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too... if she lives long enough. A wealthy industrialist offers to pay for Sarah to have a rollback—a hugely expensive experimental rejuvenation procedure. She accepts on condition that Don, her husband of sixty years, gets a rollback, too. The process works for Don, making him physically twenty-five again. But in a tragic twist, the rollback fails for Sarah, leaving her in her eighties. While Don tries to deal with his newfound youth and the suddenly vast age gap between him and his wife, Sarah struggles to do again what she’d done once before: figure out what a signal from the stars contains.
