In a very distant future an alien spaceship will come across one of the Voyager spacecrafts. And when they do, they will find two things: a golden disc — a space-proof metal version of a normal vinyl record containing sounds, music and images from Earth — and a a record player.
When that happens, we will subject the aliens to the same torture that gadget companies have been imposing on us for decades: a user manual. It’s not hard to imagine that this reason alone will be enough to cause an interplanetary war.
When NASA started to work on the Voyagers, Carl Sagan and other scientists working in the project wanted to include a description of us and our planet, for anyone who could come across the spaceships, being alien or human. His words:
The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this ‘bottle’ into the cosmic ‘ocean’ says something very hopeful about life on this planet.
Sagan also publicly said that “the record is best seen as a time capsule or a symbolic statement more than a serious attempt to communicate with extraterrestrial life” but, knowing his views on the matter, I can’t help but think that he probably had some hope about it being found by someone.
To that effect, a team started to curate a list of sounds, music pieces and images that would be the perfect representation of planet Earth. Or, at least a nice testimony of our understanding of it.
They recorded all this data in analogue form on one side of the disc. That was the only technology available at the time, when they launched in 1977. No MP3s or JPEGs or animated GIFs. On the other side of the disc they etched a quick reference card. I can’t make any sense out of it, but obviously I’m neither an engineer nor an alien, despite what some of my wives have said.
If they are successful at deciphering this gibberish — and, given that they will have interstellar spaceships, chances are that they will be more successful than you or I — they will get to listen to the sounds in this video among many others. Some of them are quite scary. I don’t know if I would like to visit Earth after listening to them — although, by the time someone finds this, the things making those sounds will probably be gone from the face of the planet. Including Jimmy Carter, who recorded the following:
This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours.
Never a greeting card was so gloomy as this one.
The aliens will also get to hear music from Beethoven, Mozart, Bach and Stravinsky, along with Blind Willie Johnson and Chuck Berry. I’m quite happy to know that Berry will be rocking in the clean room of some Imperial Star Destroyer. Roll Over, Vader.
They will also find the images in the second video. 116 images encoded in analogue form, composed of 512 vertical lines — a video signal that will play fine in any old TV set. The images were selected to give a good idea of our place in the universe, showing everything from the planets in our solar system to our internal body structure (always nice to show your guts to hungry aliens) and different scenes from Earth.
Incredibly enough, among the images there weren’t any pictures of a naked man or woman, showing us bare as species. Apparently, NASA told Sagan and his colleagues that they wanted to avoid the controversy of the Pioneer plaque, which was attacked by prude conservative groups in the United States — which I guess is a testimony of the sad state of things in this country at the time (and now).
I didn’t learn about that until today and I’m speechless that NASA conceded. It seems that some people were — and still are, I’m sure — afraid to show human penises and breasts to an alien civilisation travelling in a spaceship. Think about that. Now that is reason enough to wipe out our planet. Or at least, abduct all those morons. Maybe that’s what the rapture is all about.
In any case, chances are that aliens will hear and see us way before someone crosses paths with this golden greeting card. Radio signals travel way faster than Voyager — at the speed of light — and in every direction. And we have been sending them for decades now.
