The sublight colony starship Leonora Christine, powered by a Bussard Ramjet, is damaged while passing through a small nebula. The decelerator mechanism is disabled and cannot be repaired unless a region of empty space is reached. The crew elects to continue accelerating in order to find a refuge. Due to the effects time dilation as the ship claws ever closer to the speed of light, ship time and outside time become increasingly disconnected. As the months and years pass on board, eons pass outside.
Tau Zero is an acknowledged science fiction classic. Some parts have not aged too well, in particular the 1960s social mores and optimistic view of the human races’ collective rationality. Some of the content also feels a bit like padding, most likely because it started out as a short story. However it remains a well executed hard science fiction story which manages to bring home the insignificance of individuals, and even of humanity itself, when confronted with the almost unimaginable vastness of time and space.
Genesis is set entirely within the four-hour examination for Academy admission of one Anaximander. The Academy rules the society of the future, and Anax is one of the very few chosen for examination. The examination focuses on her chosen subject, the life of Adam Forde, who committed a peculiar act of rebellion, and received an even more peculiar sentence for his crime.
The story is quite short, a novelette in fact, and is told through the examination dialogue and recreation of historical record. Society has devolved into war and plague, civilization destroyed but for one remote and isolated pocket. This pocket must defend itself against the plagues ravaging the outside, and rebuild into a new society. The second part of the book deals with the nature of consciousness, with surprising results.
The novel is explicitly a reflection and discussion on humanity, on what it means to be human, to be a thinking being. Mr. Beckett cleverly uses Anax’s examination and the history of society and Adam Forde to explore the subject from a philosophical viewpoint without making it tedious philosophical discourse. A very interesting read.
