La época es el siglo XXI. Los personajes son cincuenta especialistas: hombres y mujeres elegidos tras un largo y cuidadoso proceso de selección destinado a incorporar sólo personal particularmente entrenado en el viaje espacial y excepcionalmente apto para desarrollar con éxito una nueva colonia. La nave es la Leonora Christine, la más reciente de su clase. Y todos los esfuerzos están puestos al servicio de una única misión: viajar a través del espacio interestelar hasta un lejano planeta donde debe establecerse una colonia terrestre.Sin embargo dos años después de su partida, la Leonora Christine colisiona con una nube de desechos del espacio, se avería y la ruta se altera. Todos se ven irremediablemente sin fin hacia lo desconocido.

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. Nominated for Hugo Award for Best Novel in 1971.

Maestro della fantascienza spaziale, autore di celebri saghe come quella del mercante van Rijn e della Lega Palesotecnica, Anderson è festeggiato in questo volume con tre celebri avventure “indipendenti” che non appartengono a cicli ma ce lo mostrano in tre diverse sfaccettature della sua poliedrica carriera; Quoziente 1000 è una straordinaria avventura del pensiero che parte da un’ipotesi affascinante: che accadrebbe se all’improvviso il quoziente intellettuale di tutta l’umanità aumentasse di dieci o venti volte? Quali orizzonti si schiuderebbero alla nostra conoscenza e alla nostra immaginazione? Le amazzoni è la storia di un pianeta dove le donne sono molto, ma molto bellicose; Tau zero, infine, racconta con grande verosimiglianza un viaggio nello spazio a bordo di un’astronave relativistica e dell’incidente che trasforma quest’avventura in un incubo dove spazio, tempo e dimensione cessano di avere ogni significato a noi noto.
