Stephen Hawking, the famous cosmologist, astrophysicist, theoretical physicist and other things ending in ist, has been noted as saying, "If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans," meaning that the history of an advanced civilization meeting a less advanced one isn't pretty. The civilization on the lesser end of things might face anything from being taken advantage of to being nearly wiped out for the sake of “progress” of more advanced one. This very scenario has been played out time and time again throughout history and been explored more times then one can count in film. Today I found myself thinking about this very subject and also the fact that some scientists think it would be a bad idea for us to send signals into the black void we call space, all for the very reasons above.
The fact is, unfortunately we've already unintentionally been advertising our presence since the creation of the radio. While it might not be the biggest billboard in the world, we send all sorts of signals besides radio into space that increase it's size significantly. Advanced intelligences from other worlds could be listening to our music, monitoring our communications, or even watching our television shows. It was this that got me to wondering, could they be watching our programs on “them”, whether it be science fiction like Star Trek or documentaries like the History Channel's Ancient Aliens? In the case of the later, could that show or others on ancient astronaut theory be used to their advantage if they happened to harbor some not so friendly intentions? What better way to gain the favor of an unassuming, less advanced species then to come down claiming to be their gods of old despite the fact they aren't? We're essentially giving them a prepackaged cover story.
Perhaps I'm thinking to much into it, then again perhaps I'm not. We could for all we know been unintentionally shooting ourselves in the foot all those signals we unintentionally send into deep space. Blaming ourselves however is really worthless, after all, we have no reason to even assume that that's the case, and from what I know of the UFO phenomenon, things in the end are probably a lot more complicated then we may truly know. However before future scientists decide to fire up a new fangled super strength communication method, perhaps they need to stop and ask what might happen if it works to well.
