Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

En ce début de treizième millénaire, l'Empire n'a jamais été aussi puissant, aussi étendu à travers toute la galaxie. C'est dans sa capitale, Trantor, que l'éminent savant Hari Seldon invente la psychohistoire, une science nouvelle permettant de prédire l'avenir. Grâce à elle, Seldon prévoit l'effondrement de l'Empire d'ici cinq siècles, suivi d'une ère de ténèbres de trente mille ans. Réduire cette période à mille ans est peut-être possible, à condition de mener à terme son projet : la Fondation.

Thousands of years ago, Earth's terraforming program took to the stars. On the world they called Nod, scientists discovered alien life - but it was their mission to overwrite it with the memory of Earth. Then humanity's great empire fell, and the program's decisions were lost to time. Aeons later, humanity and its new spider allies detected fragmentary radio signals between the stars. They dispatched an exploration vessel, hoping to find cousins from old Earth. But those ancient terraformers woke something on Nod better left undisturbed. And it's been waiting for them.

In the vein of classic authors such as Robert Heinlein, Isaac Asimov, and Arthur C. Clarke, Nathan Arkwright is a seminal author of the 20th century. At the end of his life he becomes reclusive and cantankerous, refusing to appear before or interact with his legion of fans. Little does anyone know, Nathan is putting into motion his true timeless legacy. Convinced that humanity cannot survive on Earth, his Arkwright Foundation dedicates itself to creating a colony on an earthlike planet several light-years distant.

When Chen’s parents are incinerated before his eyes by a blast of ball lightning, he devotes his life to cracking the secret of the mysterious natural phenomenon. His search takes him to stormy mountaintops, an experimental military weapons lab, and an old Soviet science station. The more he learns, the more he comes to realize that ball lightning is just the tip of a new frontier in particle physics. Although Chen’s quest provides a purpose for his life, his reasons for chasing his elusive quarry come into conflict with soldiers and scientists who have motives of their own.

For generations the solar system--Mars, the moon, the asteroid belt--was humanity's great frontier. Until now. The alien artefact working through its program under the clouds of Venus has emerged to build a massive structure outside the orbit of Uranus: a gate that leads into a starless dark. Jim Holden and the crew of the Rocinante are part of a vast flotilla of scientific and military ships going out to examine the artefact. But behind the scenes, a complex plot is unfolding, with the destruction of Holden at its core.

In the midst of an interstellar war, Yun Tianming found himself on the front lines. Riddled with cancer, he chose to end his life, only to find himself flash frozen and launched into space where the Trisolaran First Fleet awaited. Captured and tortured beyond endurance for decades, Yun eventually succumbed to helping the aliens subjugate humanity in order to save Earth from complete destruction.

When it comes to artificial intelligence, we’re no longer in a “what if?” reality. We’re squarely in a “now what?” world. From books to financial markets, from healthcare to research, the age of artificial intelligence has arrived. We’re in for a ride, and it’s anything but smooth. What will the world look like as we share it with the genie we let out of its digital bottle? How will AI evolve? Perhaps, even more important, how will we?

WB and Feral have survived the attack on SPARK, but the terrorists are not through.

Flying below the radar kept them safe before, but increased notoriety works against the two as everyone from the FBI to gang members know who they are. Now, local bureaucrats, terrorists, and even fans intrude on the gamers’ lives.

In the near future, the nano-drug Nexus can link mind to mind. There are some who want to improve it. There are some who want to eradicate it. And there are others who just want to exploit it. When a young scientist is caught improving Nexus, he’s thrust over his head into a world of danger and international espionage, with far more at stake than anyone realizes.

In his mother’s last letter, she wrote, “Find me. Save me.” And Will Kwan had heard those words before. He’d heard them in a video game. Solar Prime Augmented Reality Park, or SPARK, is a theme park for gamers: a sprawling virtual reality complex with quests and games that appeal to all ages. But beneath the surface, SPARK harbors many a secret. When sixteen-year-old Will has to escape the foster system, SPARK is his destination. “Find me. Save me.” What had his mother meant?

The 21st century will see great changes for humanity. True Artificial Intelligence comes into existence, and in its wake the world is ripped apart and reborn.

Now, in 2049, the “longevity plague” has engulfed the world. There are half a billion super-centenarians worldwide who should be dead but live on. They’re called Lingerers, or the Undead, or Lifers.

In 1638, in the first age of modern astronomy, as the starts opened up to us, the scientists of the time found themselves bound into fantastical visions based on their new knowledge. This was perhaps the first 'hard' sci fi, at least based on the cutting edge of knowledge from the time. Drawing on contemporary theories of Copernicus, Kepler, Galileo, and Gilbert, the inhabitants of the Moon in this story are a tall Christian people encountered by a roguish hero who must learn of their lands, and gains items that allow the control of light, heat, and gravity.
