Stay home, E.T.: Stephen Hawking says aliens may pose risks | detnews.com | The Detroit News: "British astrophysicist Stephen Hawking says aliens are out there, but it could be too dangerous for humans to interact with extraterrestrial life. Hawking claims in a new documentary that intelligent alien lifeforms almost certainly exist, but warns that communicating with them could be 'too risky.'
The 68-year-old scientist says a visit by extraterrestrials to Earth would be like Christopher Columbus arriving in the Americas, 'which didn't turn out very well for the Native Americans.'"
Comment -- At first glance, this may strike people as kind of a loony comment by Hawking. But it's a commonly expressed viewpoint in astronomy circles. And, when you consider that we've detected hundreds of planets circling nearby stars...maybe it's a good idea after all for humans to hunker down and hope no one notices us.
