In a new Discovery Channel documentary to be aired in May, renowned astrophysicist Dr. Hawking suggests that with 100 billion galaxies in the universe it seems “perfectly rational” that aliens exist. While they are most probably microorganisms or basic animals, he suggests the threat posed by intelligent life forms, if they exist, could make reaching out to them “a little too risky.”
“We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach,” he said. “If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the native Americans.”Stephen Hawking aliens theory doesn't scare planet hunters - CSMonitor.com“Ignoring the possibility [alien life] and hiding your head in the sand, waiting for them to find us certainly isn’t a scientifically intelligent way to proceed or a good cultural way to anticipate something like that either,” says Mary Voytek, senior scientist for astrobiology at NASA. “Our approach to it has been to be prepared. We’re not going to get caught, say like the native Americans when Columbus came to their shores. We’ve been actively listening and hopefully we get some information before any eventual encounter ever happens.”
As for how we would fare on the business end of an invasion, the only realistic scenario was shown in the total downer Skyline. Know why audiences hated it? Because we lost. Badly. Which is the only possible end result of being invaded by an alien race so technologically advanced that they could successfully cross millions of light years to reach us. Trust me, if we were smart we'd stay nice and quiet until we understood what the hell was out there.
