The universe shifts and changes: suddenly you understand, you get it, and are filled with wonder. That moment of understanding drives the greatest science-fiction stories and lies at the heart of Engineering Infinity. Whether it's coming up hard against the speed of light - and, with it, the enormity of the universe - realizing that terraforming a distant world is harder and more dangerous than you'd ever thought, or simply realizing that a hitchhiker on a starship consumes fuel and oxygen with tragic results, it's hard science-fiction where a sense of discovery is most often found and where science-fiction's true heart lies. This exciting and innovative science-fiction anthology collects together stories by some of the biggest names in the field, including Gwyneth Jones, Stephen Baxter and Charles Stross.
