I want it clear that I am not being kept awake at night by this thought. I have better things to steal my precious and sorely needed moments of rest from me. But I do have this thought coming. You know how the Voyager spacecraft have some gold-printed records with sounds of Earth, everything from children laughter to greetings from Jimmy Carter to Chuck Berry music, on them? Suppose it is ever picked up by aliens who figure out what the record is and the basics of how to play it. How do we keep them from playing the record backwards?
I know, I know, there’s supposed to be instructions on how to play it that we think aliens clever enough to grab a space probe will be able to work out. But I also know that humans are fantastically sucky at coming up with instructions for things. There’s packages of macaroni and cheese with instructions I find intolerable ambiguities in. Communicating how to set up and play a record to creatures with presumably no understanding of human norms? There’s no chance we’ve gotten that anywhere near right.
And all right, so it won’t be a big problem if a quarter-million years from now some aliens we don’t even know yet hear Chuck Berry backwards. And even if they play the record the right way around we won’t know that they won’t mishear things and come to Earth looking for more Chuck Barris. That’s at least something we get for the bother of being mortals.
Also, you know what? You could use a little Sparks in your life. Enjoy.
