Do you see it?”The question was rather unnecessary. Beta was almost at zenith, itsruddy light flooding the landscape to an unusual orange as the brilliantrays of setting Gamma died. Beta was at aphelion. It was small; smaller thanTheremon had ever seen it before, and for the moment it was undisputed rulerof Lagash’s sky.Lagash’s own sun, Alpha, the one about which it revolved, was at theantipodes, as were the two distant companion pairs. The red dwarf Beta — Alpha’s immediate companion — was alone, grimly alone.Aton’s upturned face flushed redly in the sunlight. “In just under fourhours,” he said, “civilization, as we know it, comes to an end. It will doso because, as you see, Beta is the only sun in the sky.” He smiled grimly.“Print that! There’ll be no one to read it.

    It is part of Asimov's Robot series, and was the second of Asimov's positronic robot stories to see publication.Powell and Donovan are assigned to a space station which supplies energy via microwave beams to the planets. The robots that control the energy beams are in turn co-ordinated by QT1, known to Powell and Donovan as Cutie, an advanced model with highly developed reasoning ability. Using these abilities, Cutie decides that space, stars and the planets beyond the station don't really exist, and that the humans that visit the station are unimportant, short-lived and expendable. QT1 makes the lesser robots disciples of a new religion, which considers the power source of the ship to be "Master."

    Here are smart, savvy tales of space adventure, time travel, weird science, mysterious phenomena, apocalypse and dystopia, tales that reflect the concerns of their day, yet eerily foreshadow our own. There's Successful Operation, a Twilight Zone-ish gem in which a dictator gets his just desserts...Let There Be Light, about two inventors who triumph over political corruption...and On the Slopes of Vesuvius, in which a Bomb-fearing barkeep sees his worst fears realized. -And He Built A Crooked House- tells of an architect whose innovative home design leads straight into a funhouse fourth dimension. Solution Unsatisfactory gives us a chilling alternate end to WWII, while -All You Zombies- paints a time-twisty picture of the ultimate causality paradox. All these and more, including three previously uncollected stories, Beyond Doubt, My Object All Sublime and Pied Piper, display Heinlein's creative genius to full extent.
