La última pregunta, una obra maestra de la ciencia ficción, es, tal y como afirmó su autor en repetidas ocasiones, por encima de toda duda, mi favorita entre todas las historias que he escrito en mi carrera. ¿Es posible revertir el inevitable final del Universo, o el mundo debe acabar de todas formas? es la pregunta que desde un día del siglo XXI, hasta generaciones y generaciones posteriores en el tiempo, hacen los humanos a los ordenadores.

Watch out - the Earth just fell into a dark sun's orbit! Or maybe you'd rather visit a theme park called Hell? These are just two of the strange and unnerving tales you'll find in this collection of great science fiction and fantasy stories.

The industrialist's son, Red, has found two strange animals, and he enlists Slim in a plan to turn the animals into a circus act.

Faced with determining the fate of the galaxy, Golan Trevize hesitantly chose to hand over the rule of the galaxy to planet Gaia. Two mysteries now remain: who has erased the records of Earth – and why?

But nothing could prepare them for the secrets which await them on Earth. Secrets which predate history as they know it, and will change its significance forever.

Desde hace doce mil años, la humanidad prospera en una galaxia gobernada por el Imperio desde la majestuosa ciudad de Trántor. Todos creen que la estabilidad durará para siempre hasta que Hari Seldon predice, mediante su revolucionaria teoría de la psicohistoria, un futuro de ruina y destrucción. Desterrado al planeta Terminus, Seldon establecerá una colonia con las mentes más brillantes del Imperio, una Fundación que esconde la clave para cambiar el destino de la galaxia.

In a time before the Foundations, psychohistory’s creator Hari Seldon is made to stand before the Emperor of the crumbling Galactic Empire to present how his scientific theory of predicting the future might be applied to the real world. However, Hari refuses to deploy his theory for political gain, setting off instead with reporter Chetter Hummin in quest of a place to safely apply his theory: Earth, the original home of humanity. All records of Earth have been lost to time. Hari will therefore have to look back into the past, in order to seal the future of humanity for ever.

Un clásico entre los clásicos de la ciencia ficción. Esta historia, que apareció por primera vez en 1976, fue mi exposición más clarividente del desarrollo de los robots. Trataba del deseo de un robot de convertirse en hombre y la forma en que realizaba este deseo, paso a paso. No tenía intención de escribir esta historia cuando la empecé, se escribió sola, y se trazó y entrelazó en la máquina de escribir. Acabó siendo la tercera de mis historias favoritas, entre todas las escritas.

Guiada por su fundador, el gran psicohistoriador Hari Seldon, la Fundación ha logrado sobrevivir a la amenaza de barbarie de sus planetas vecinos. Pero ahora debe enfrentarse al Imperio, que, pese a su decadencia, sigue siendo la fuerza más poderosa de la galaxia. Y nadie ha podido prever el nacimiento de una extraordinaria criatura llamada el Mulo, una inteligencia mutante dotada de poderes paranormales capaces de convertir al humano más combativo en un dócil esclavo.

When the technology for twisting to other probability patterns was developed, a grateful Earth solved its overcrowding by sending people to live on Earths where plants and animals never got started. Each family could have its own planet, because there was an infinite number of such alt-Earths available, and the computers never assigned the same one twice. Trouble was - someone else had the same idea!

Andrew Harlan’s job is to range through past and present centuries monitoring and even altering Time’s myriad cause-and-effect relationships. As a Technician with the Allwhen Council, he initiates Reality Changes that may affect the lives of as many as fifty billion people – and a million or more of them may be so drastically affected as to be considered new individuals. Above all, therefore, a Technician must be dispassionate. An emotional make-up is a distinct handicap. Then Harlan meets Noÿs and falls victim to a phenomenon older than Time itself – love.

What would a child of the future envision a classroom of the 20th century to look like? This is a question that is explored in a rare piece of science fiction from master writer Isaac Asimov. Listen in to two children of the 22nd century as they explore their first-ever book. Everything they know comes on a screen and they're not sure what to do with a book. While written decades ago it's uncanny to hear the similarities to our present.

A research spaceship from Earth lands on Saybrook's Planet to investigate a report by an earlier colony ship. The colony ship's captain, Saybrook, had reported that the planet's abundant plant and animal life was all part of a single organism with a unified consciousness. That organism was able to induce pregnancy in all the colony ship's female animals, and all the offspring born had green patches of fur instead of eyes, a sign that they were part of the planetary organism.
