Tau Zero (SF Collector's Edition) (Gollancz SF Collector's Edition)

Poul Anderson's Tau Zero is an outstanding work of science fiction, in part because it combines two qualities that are often at odds in this genre: an interest in the emotional lives of its characters and a fascination with all things technological and scientific. In Tau Zero these components are not merely fused; they work together with a remarkable synergy that makes the novel much more than just a deep space adventure story.The novel centers on a ten-year interstellar voyage aboard the spaceship Leonora Christine, and it opens with members of the crew preparing for their departure from earth. It is an especially moving departure because they know that while they are aboard the ship and traveling close to the speed of light, time will be passing much more quickly back home. As a result, by the time they return everyone they know will have long since died. From practically the very first page, therefore, Tau Zero sets the scientific realities of space travel in dramatic tension with the no-less-real emotional and psychological states of the travelers. This is a dynamic Anderson explores with great success over the course of the novel as fifty crewmembers settle in for the long journey together. They are a highly-trained team of scientists and researchers, but they are also a community of individuals, each trying to make a life for him or herself in space.This is the background within which the action of the novel takes place. Anderson carefully depicts the network of relationships linking these people before the real plot begins to unfold. The voyage soon takes a unexpected and disastrous turn for the worse. The ship passes through a small, uncharted, cloudlike nebula that makes it impossible for the crew to decelerate the ship. The only hope, in fact, is for the ship to speed up. But acceleration towards the speed of light means that time outside the spaceship passes even more quickly, and the crew finds itself hurtling deeper into space and further into the future. Anderson's experience as a physicist is evidenced in the knowledgeable way he discusses the technical details of space and time travel, although his explanations never become burdensome or tedious. More to the point, the painstaking care with which he has drawn the characters ensures that the action is both imaginatively compelling and emotionally meaningful. It is a combination that is unfortunately all too rare in science fiction. Fifty men and women set out in the twenty-third century from Earth aboard an interstellar craft to travel to a planet some thirty light-years away. The ship will approach the speed of light and so (as Einstein predicted) subjective time on board will slow and so the journey of several decades will be of much shorter duration for the crew. But the ship's deceleration system is irreparably damaged when it hits a cloud of interstellar dust and acceleration continues toward light speed, tau zero. Soon the ship is speeding through galaxies and eons are passing on board the ship in the blink of an eye .. For the crew of the Leonora Christine, travelling close to the speed of light on a 30-light-year journey, subjective time slows down. Then buffeting by an interstellar dust cloud damages the ship's deceleration system and it achieves light speed, tau zero itself.
