Chapter 4

An apparent train of interstellar communication signals of unknown origin and destination has been observed. Since interception was made by biological sensors, a biological-type signal transmission must be assumed. Test experiments were conducted in an electromagnetic deep-fringe area, the equipment itself being impervious to electromagnetic radiation. Follow-up tests revealed no equipment defects. Because interstellar listening experiments are not conducted on a routine basis, the suggestion is advanced that verification tests should be conducted elsewhere, possibly on a global scale. The phenomenon is too important to be ignorant.

[L. George] Lawrence’s most important conclusion, that biological-type sensors are needed in order to intercept biological signals, applies particularly to communications from outer space. As he puts it: “Standard electronics are next to worthless here, since ‘bio-signals’ apparently reside outside of the known electromagnetic spectrum.”

Pointing out that in our own galaxy alone there are some 200 billion stars, Lawrence says that if one assumed each of them to have at least five companion planets, a total of one trillion might consequently be available for study. Even if only one planet in a thousand has intelligent life this would amount to one billion in our galaxy alone. Multiplied by the ten billion galaxies believed to comprise the observable universe, then there may be 10,000,000,000,000,000,000 planets capable of sending some kind of signal to Earth.
