Besides the infamous War of the Worlds hoax that people actually thought was a bona fide radio broadcast -- never mind Roswell and the onslaught of government conspiracy theories that followed -- there have been a myriad of times actual scientists thought unusual signals from space were some attempt by intelligent life trying to make contact with us Earthlings (or at least trying to get around in their starships). But were they?
Science tends to err on the side of natural phenomena, which is what some of the signals eventually turned out to be. This is space -- there is a chance that naturally occurring oddities could be exponentially weirder than anything someone could dream up in a science fiction novel. However, when even Stephen Hawking insists there must be intelligent life somewhere, you get to wondering.
Blast off into World Space Party 2017 and explore these nine far-out occurrences, some of which remain unsolved ... and theorize for yourself.
