Remember the 1st Voyager mission? The one that has long since left our solar system... and if I remember right..., includes a kind of Mathematical Communication Coding (cuz math is a universal language), a recording of Johnny B. Goode, and a map showing where to find us. You know, so that the E.T.'s of the universe can know how we boogie, and exactly how to get here? Well, I've always wondered, what if the 'intelligent life' that finds Voyager isn't so into Rock & Roll..., but IS into eating things like us? Personally, I don't think that's all that far fetched.
....and who the H E double Hockey Sticks gets to make THAT call??
