Aliens Among Us
The BBC reports that at least one American scientist thinks we don't have to leave home to find aliens.
"We don't have to go to other planets to find weird life. It could be right in front of our noses - or even in our noses," the BBC quotes Paul Davies, an Arizona State University scientist, as saying.
Those who, like Davies, think there might be more here on Earth than we know, subscribe to a theory that says life has evolved here more than once, creating a shadow biosphere-- a second set of life forms that live so differently from what we know that we might not have thought to look for them. Davies warns the BBC, though, that he's not talking about the kind of alien life found on Star Trek.
Davies, a theoretical physicist, managed to reference Star Trek, "smoking but not inhaling," graduate student labor, and a "Mission to Earth" all in one interview with a trusted news source, while also explaining the scientific background to his reasoning. Who knows-- if he can do that, maybe he can find aliens among us too.
