"If you had to pick, would you rather be deaf or blind?" I find this question a very hard one, because both sound and sight are fantastic gifts of life. But more specifically, what is it in our ability to see and hear things that makes it so fantastic? What sounds and sights is human kind proud of?
In 1977, NASA launched the twin Voyager spacecraft, two relatively small contraptions, each going into a different direction, that initially were designed to explore our solar system. By now they are in the on the borders of our solar system (heliosheath in nerd-talk), and at over 50,000 km/h the Voyager 1 and 2 are looking for extraterrestial life. On board of these spacecrafts there is a "Golden Record", an LP with the sounds and pictures of Earth. Dozens of experts and scientists worked together to create the content of this Golden Record, so in finding out what human kind is proud of on our planet it may be a good idea to run that record.
Firstly other life forms would have to be able to play the record, which is why the cover of the Golden Record has a description of how to do it:
Not exactly an IKEA-style description of how to put your dinner table together...Anyway, assuming extraterrestial life gets it, they will hear the following:
Sounds:
Greetings from Earth: From an Akkadian (one of our oldest languages) "May all be very well", to an Amoian (a Chinese dialect) "Friends of space, how are you all? Have you eaten yet? Come visit us if you have time."
Music from Earth: the usual Bach, Beethoven and Mozart, but also Senegal percussion and Azerbaijan bagpipes, tribal chants and Peruvian wedding songs, Mexican Mariachi and Indian raga. Sounds like an amazing blend - I wonder what the Martians will think.
Sounds from Earth: volcanoes, earthquakes, thunder, mud pots, wind, rain, crickets, frogs, birds, hyenas, elephants, chimpanzees, wild dog, footsteps, heartbeat, laughter, fire, sheep, a blacksmith, sawing, tractor, morse code, ships, horse and cart, train, bus, automobile, F-111's, rocket lift-off, kiss, mother and child, pulsar...mind you, the record was made over 3 decades ago, but it's still a pretty solid mix :)
Sights:
Scenes from Earth: the most extreme range of pictures have been put on this record. Mathematical formulas, continental drifts, a nursing mother, people licking eating and drinking, a page of a book, sunset with birds, pictures of different peoples, string quartet, animals, famous buildings and sights, anatomical pictures, etc etc.
I'm still not sure what my final answer would be when asked the question I posed in the first paragraph of this post. Maybe that's because I've been so lucky to have been born with both and take it for granted too often. Maybe we should ask the aliens that managed to play the Golden Record what they were most flabbergasted about...because I assume they will be...
