He's one of the most celebrated scientific brains in the world, so how seriously do you take Professor Steven Hawking's claims that looking for alien life is a ?
"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," he says in a new documentary.
Hawking calls the existence of life beyond earth but warns that humans may not like what they find.
that Hawking has got the wrong end of the stick.
The danger as Hawking puts it is that any life we encounter may well be more advanced than ours and be on the hunt for raw materials, just like nomads....But that supposes any alien race would think and react socially anything like the human race. Maybe the reason we haven't been visited yet (to our definite and provable knowledge that is), is that the aliens want to avoid this bloodthirsty race.
Lots of are discussing Hawking's claims, but should the human race carry on pushing the boundaries to try and find the unknown?
