They may have monitored the rapid changes in atmospheric temperature caused by those greenhouse gas increases. They may have observed the rapid increase in Earth’s greenhouse gas levels over the past several centuries, coincident with the development of an industrialized civilization. Perhaps there are watchers out in the void, guardians of the galaxy, possessors of technologies we cannot even imagine. That communication problem requires our urgent attention.
WHO RECORDED FOR THE GOLDEN RECORDS ABOARD VOYAGERS 1 AND 2 HOW TO
Four decades after launching Voyager, we still have not figured out how to communicate thoughtfully with others in this country who are not like us. The golden record was an attempt to communicate with distant alien civilizations. Cover for the golden "Sounds of Earth" records aboard Voyager 1 and 2, depicting how to play the record and some basic information about our home planet. This willful ignorance is jeopardizing our planetary life-support system.
Powerful politicians are ignoring and devaluing scientific understanding, and are incorrectly dismissing human-caused climate change as a hoax. It is less clear in 21st century America. Now, forty years after launching the bottle, the beauty and power of science is still clear to most of the rest of the world. “That will tell you where we live.”Īs Carl Sagan put it, we released a “bottle into the cosmic ocean." Science was our way of helping any finders read the message in the bottle. “Look at Earth with respect to these 14 pulsars”, the record said. The record makers wrote down our home address by locating the solar system relative to prominent cosmic landmarks. The assumption was that advanced civilizations all spoke the language of mathematics, atomic physics, chemistry, and astronomy. The producers of the record had to encode the sounds and images of Earth in a way that made this information understandable by potentially very different forms of intelligence. It was also about the beauty and power of science. The golden record was about who we are, and the planet we call our home.
We wanted to make a good impression on any potential listeners out there. Encodings of our brain waves, and images of our science and culture. Recordings of human laughter, and the haunting sounds of whale song. Voyager carried a golden record-a sampler of the greatest hits of life on Earth (it's twin, Voyager 2, had an identical record). On September 5, 1977, almost exactly 40 years ago, the Voyager 1 probe was launched into the darkness of space.
