On June 3, 1977, Ann Druyan remained still while medical sensors captured the electrical activity of her heart, brain, eyes, and muscles. She was creating a physiological representation for the Voyager Golden Record, the communiqu\u00e9 from Earth that would soon embark aboard two spacecraft. Just two days prior, she and Carl Sagan had confessed their love for one another.<\/p>\n

Druyan utilized the recording session to think intentionally. She traversed the history of Earth, the progression of life, and the emergence of human civilization. Then she reflected on love and on Sagan. The signals from her body were transformed into sound and condensed into approximately a minute on the record.<\/p>\n

The emotional narrative is genuine, but it requires one scientific clarification. The recording does not serve as a decipherable replicate of Druyan\u2019s thoughts. Instead, it consists of a series of physiological measurements. We understand the significance of that minute because Druyan later provided the narrative.<\/p>\n

Two days between the call and the electrodes<\/h2>\n

Druyan was the creative director for the Golden Record project. Sagan, an astronomer at Cornell University, held the position of executive director. In early June, the team was racing against time to complete the disc before the Voyager launches later that summer.<\/p>\n

In a personal account shared with Radiolab<\/a>, Druyan reflected on searching for a Chinese composition the team wished to include. Upon discovering a suitable recording, she called Sagan. When he returned the call, their discussion quickly progressed far beyond the music. They professed their love and opted to marry, having never kissed nor engaged in a personal conversation of that nature before.<\/p>\n

The call occurred on June 1. The physiological recording was set for June 3. This close timeline is pivotal to the narrative: the session had already been arranged, but Druyan approached it with an emotional state that had evolved in the preceding 48 hours.<\/p>\n

She and Sagan wed in 1981 and remained together until his passing in December 1996. Their relationship did not originate from the Golden Record, but it developed within the fervent collaboration necessary to create it.<\/p>\n

What \u201cAnn\u2019s heartbeat\u201d actually holds<\/h2>\n

The common shorthand makes the recording seem more straightforward than it actually was. In a later Science Friday interview<\/a>, Druyan described an hour-long session that captured an electrocardiogram, or EKG, in addition to an electroencephalogram, or EEG, eye movement, and other bodily signals. These measurements were transformed into audio and significantly compressed for the disc.<\/p>\n

An EKG gauges voltage fluctuations associated with the heart\u2019s electrical process. This can generate the recognizable rhythm that listeners connect with a heartbeat. An EEG measures varying electrical activity at the scalp, reflecting the collective behavior of large groups of neurons. Eye and muscle sensors contribute additional changing patterns.<\/p>\n

None of these devices transcribes a person\u2019s thoughts. An EEG can illustrate rhythms and general states, but does not provide a linguistic record of what someone is thinking. There is no decoding tool on the Golden Record that translates Druyan\u2019s brain activity back into her reflections on evolution, history, or Sagan.<\/p>\n

Druyan has occasionally envisioned that a sufficiently advanced future listener might derive more from the signals than individuals can today. That is a conjecture, not a verified characteristic of the recording. The scientifically valid assertion is narrower: the disc contains physical traces generated by her body while she was contemplating those thoughts. The thoughts themselves endure through her account.<\/p>\n

The record encompassed more than a single love story<\/h2>\n

The Golden Record was crafted as a concise introduction to Earth. NASA\u2019s catalog of its contents<\/a> details spoken greetings, music from various traditions, natural sounds, human activities, and encoded images. The physiological recording is situated within a sequence of sounds that also features footsteps, laughter, and a mother with a child.<\/p>\n

It was also a collaborative endeavor. NASA credits Sagan as executive director, Frank Drake as technical director, Druyan as creative director, Timothy Ferris as producer, Jon Lomberg as designer, and Linda Salzman Sagan as the organizer of the greetings. Hundreds of voices, performers, photographers, scientists, and rights holders contributed to the<\/p>\n","protected":false},"excerpt":{"rendered":"
