Stephen Hawking, the worlds most intelligent man, has a new documentary on the Discovery Channel called "into the Universe".

"One piece of advice that Professor Hawking doesn't mind sharing is the less-popular notion that it might be better if we kept our location a secret rather than being so anxious to make contact," says Discovery.

"Reaching out to the stars with our messages of curiosity and peace may only make it easier for an advanced alien mining operation to stake a claim on Earth. First contact would be a much better proposition if we can wait until we are on more equal terms." The point made here does make sense, we are constantly wanting to make contact with them, however what if they just wanted to use our resouces? A far smarter intelligent life form will always win any battle.

I imagine they might exist in massive ships... having used up all the resources from the planet below," Professor Hawking says.

"Such advanced aliens would perhaps become nomads looking to conquer and colonise whatever planets they could reach. If so, it makes sense for them to exploit each new planet for materials to build more spaceships so they could move on."
