Lesson 43-4     Are there strangers in space?

Fortunately, thereis a 'uniquely rational way' for us to communicate with other intelligentbeings, as Walter Sullivan has put it in his excellent book, We Are not Alone.This depends on the precise radio frequency of the 21-cm wavelength, or 1420megacycles per second. It is the natural frequency of emission of the hydrogenatoms in space and was discovered by us in 1951; it must be known to any kindof radio astronomer in the universe.

Once the existenceof this wave-length had been discovered, it was not long before its use as theuniquely recognizable broadcasting frequency for interstellar communication wassuggested. Without something of this kind, searching for intelligences on otherplanets would be like trying to meet a friend in London without a pre-arrangedrendezvous and absurdly wandering the streets in the hope of a chanceencounter.
