Famous astrophysicist and pop culture icon Stephen Hawking has shared some thoughts about the discovery of alien life in a new documentary "Stephen Hawking's Favorite Places." In the documentary, Hawking revisits opinions he's shared before, that if intelligent extraterrestrials are out there, they shouldn't be trusted and would probably just try to control and usurp all of Planet Earth's resources.
"One day, we might receive a signal from a planet like this," Hawking says in the documentary, referring to a potentially habitable alien world known as Gliese 832c. "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." [space.com]
Hawking cautions that NASA's attempts to find alien life could be dangerous. However, others in the scientific community aren't so fearful and believe that intelligent life would have already conquered Earth by now if they had bad intentions.... well, according to the latest government "UFO" insider, rocker Tom Delonge (formerly of Blink 182), alien races are here already, and some of them aren't friendly. So, maybe Hawking is right. (Read also: What do aliens want with humans?)
