The Far Ends of Time and Earth — Isaac Asimov

Three classics that heralded the advent of a master of science fiction

PEBBLE IN THE SKY
Joseph Schwartz is hurled into the future by some mysterious effect of fissioning uranium. He emerges into a strange and eerie world -- a radioactive Earth in the Galactic Era 827. All the planets of the Galaxy are inhabited, and the people of Earth are outcasts. Schwartz finds himself caught up in a revolution of Earth militarists -- the one man whose telepathic powers can avert an impending cosmic disaster.

EARTH IS ROOM ENOUGH
Fifteen short stories and two pieces of comic cosmic verse that do not wander from our planet. They include an absorbing tale of the frightening possibilities of a machine that views the past. And the chilling story of the first superslow-motion film of an atomic explosion during which the unmistakable outline of...but just what appeared in the mushroom cloud is part of the story!

THE END OF ETERNITY
An awesome mirror-within-mirror tale of one man's adventures in the 482nd century...Love was forbidden to the Eternals, but Harlan was suddenly using all his knowledge and training to preserve his life with Noys -- a non-Eternal -- knowing that one fatal move could bring doom to Eternity. The ultimate tale of time travel in which one learns that perhaps Earth is not room enough.
