Stephen Hawking Wants To Find Aliens Before They Find Us (cnet.com)
Stephen Hawking is again reminding people that perhaps shouting about our existence to aliens is not the right way to go about it, especially if those aliens are more technologically advanced. In his new half-hour program dubbed, Stephen Hawking's Favorite Places, the theoretical physicist and cosmologist said (via CNET):"If intelligent life has evolved (on Gliese 832c), we should be able to hear it," he says while hovering over the exoplanet in the animated "U.S.S. Hawking." "One day we might receive a signal from a planet like this, but we should be wary of answering back. Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn't turn out so well." Hawking manages to be both worried about exposing our civilization to aliens and excited about finding them. He supports not only Breakthrough: Listen, but also Breakthrough: Starshot, another initiative that aims to send tiny nanocraft to our closest neighboring star system, which was recently found to have an Earth-like planet.
I don't think its possible to predict what a more advanced civilization might want. Are we squirrels? Are we rats to be exterminated? Are we dogs to be bred for cuteness? Is the relationship something we are not capable of comprehending?
