British renowned astrophysicist Stephen Hawking said in his new Discovery Channel program that mathematically, it is possible that there may be other life forms in the universe.

But he also warned that encounter with such aliens can be devastating to the human race. If the aliens visits the earth, it means that they have the technology to travel in distant places in space and therefore are more advanced civilization.

The encounter might be a demise to the human civilization just like what happened to the American natives when Christopher Columbus landed in the American soil.
