An excerpt from a book would give extraterrestrials a glimpse of our written language, but deciding on a book and then a single page within that book was a massive task. For inspiration, Lomberg perused rare books, including a first-folio Shakespeare, an elaborate edition of Chaucer from the Renaissance and a centuries-old copy of Euclid’s Elements (on geometry), at the Cornell University Library. Ultimately, he took MIT astrophysicist Philip Morrison’s suggestion: a page from Sir Isaac Newton’s System of the World, where the means of launching an object into orbit is described for the very first time.
Greeting from Nick Sagan
To keep with the spirit of the project, says Ferris, the wordings of the 55 greetings were left up to the speakers of the languages. In Burmese, the message was a simple, “Are you well?” In Indonesian, it was, “Good night ladies and gentlemen. Goodbye and see you next time.” A woman speaking the Chinese dialect of Amoy uttered a welcoming, “Friends of space, how are you all? Have you eaten yet? Come visit us if you have time.” It is interesting to note that the final greeting, in English, came from then-6-year-old Nick Sagan, son of Carl and Linda Salzman Sagan. He said, “Hello from the children of planet Earth.”
Biologist Roger Payne provided a whale song (“the most beautiful whale greeting,” he said, and “the one that should last forever”) captured with hydrophones off the coast of Bermuda in 1970. Thinking that perhaps the whale song might make more sense to aliens than to humans, Ferris wanted to include more than a slice and so mixed some of the song behind the greetings in different languages. “That strikes some people as hilarious, but from a bandwidth standpoint, it worked quite well,” says Ferris. “It doesn’t interfere with the greetings, and if you are interested in the whale song, you can extract it.”
Reportedly, the trickiest sound to record was a kiss. Some were too quiet, others too loud, and at least one was too disingenuous for the team’s liking. Music producer Jimmy Iovine kissed his arm. In the end, the kiss that landed on the record was actually one that Ferris planted on Ann Druyan’s cheek.
Druyan had the idea to record a person’s brain waves, so that should extraterrestrials millions of years into the future have the technology, they could decode the individual’s thoughts. She was the guinea pig. In an hour-long session hooked to an EEG at New York University Medical Center, Druyan meditated on a series of prepared thoughts. In Murmurs of Earth, she admits that “a couple of irrepressible facts of my own life” slipped in. She and Carl Sagan had gotten engaged just days before, so a love story may very well be documented in her neurological signs. Compressed into a minute-long segment, the brain waves sound, writes Druyan, like a “string of exploding firecrackers.”
