In a universe whose size is beyond human imagining, where our world floats like a dust mote in the void of night, men have grown inconceivably lonely. We scan the time scale and the mechanism of life itself for portents and signs of the invisible. We watch the stars, but the signs are uncertain. We uncover the bones of the past and seek for our origins. There is a path there, but it appears to wander.
Lights come and go in the night sky.
Men, troubled at last by the things they build, may toss in their sleep and dream bad dreams, or lie awake while the meteors whisper greely overhead. But nowhere in all space or on a thousand worlds will there be men to share our loneliness. Nevertheless, in the nature of life and in the principles of evolution we have had our answer. Of men elsewhere, and beyond, there will be none forever. Its progressive thought and its progressive technology make the transition through time, from generation to generation, a true migration into uncharted seas of adventure.
