Sample text

Its wave-length (21 cm) gives a unit of distance, its frequency (1420 megaHertz, or 1420 million cycles per second) a unit of time. Using just the two on-off symbols of binary code, these units can spell out numbers of any size. Sagan < previous page page_26 next page > < previous page page_27 next page > Page 27 decided to specify the probe’s origin. Since our Sun has no special traits to mark it out from a billion others, Sagan focused on stellar rarities known as pulsars, super-dense stars that spin at astonishing rates, averaging about twice per second (with the fastest known pulsar spinning 625 times a second).

All messages decay with time and distance. A CD may last longer than a whisper or a smoke-signal, but on geological time-scales even CDs evaporate. It takes a continuous input of energy – like the building of CD cabinets and the application of cleaning devices – to keep channels of communication open and free of ‘noise’. Then there is the code, the form in which the message is couched. Words were out, because all linguistic links would have gone. CDs might encode enough information (though Sebeok’s advice predated computerized CDs) – but who would bet on the survival of electric power, let alone computers, let alone compatible ones?

As an English example, imagine six little images: Easy, especially if you know a little English literature. But try going on with ‘that is the question’. No common image can stand for the sound of ‘that’, because there are no one-syllable nouns that begin with a voiced ‘th’. If you want to continue the game, you have to improvise. You might, for instance, devise a literary version of charades, using a sign for ‘vat’ and another, a so-called determinative, for ‘sounds like’ or ‘rhymes with’. Cuneiform was well suited to record Sumerian, because it was built on a skeleton of syllables and four vowels, modified by prefixes and suffixes.
