An article by a German astronomer reports that radio astronomers today discuss as a distinct possibility inter-planetary conversation between earth-bound men and creatures on other planets; he "demonstrates" with intricate mathematical logic that planets suitable for life may be fairly common among the stars, and that there are "perhaps ten civilized communities within 1,000 light years of the earth," and "there may well be creatures intelligent enough on some of those planets to transmit radio messages across the enormous distances of interstellar space."
