WHAT DO YOU SAY TO AN ALIEN?
There have been several messages broadcast into space or placed on board deep space probes intended for any attentive aliens out there. But we shouldn’t be narcissistic when it comes to crafting interstellar greetings, says a group of researchers in a recent science paper. They argue that if we are, E.T. simply won’t understand what we’re trying to tell them.
Take the aluminum postcard plaque aboard the star-bound Pioneer 10 and 11 probes (pictured above). The most dominant graphic is an engraving of man and woman, his hand upraised in a greeting gesture. This is hardly a universal gesture especially if the aliens who find it have no limbs. Or it could be taken as downright obscene in some corners of the Galaxy.
