Should we look for E.T.?
The prospect of finding alien life is exciting, but... like the writer Arthur C. Clarke said: Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying. All depends on what we find - if we find anything at all. Stephen Hawking opened the can of fear. He was fine with listening and looking from the shadows; not much with telling where we are in the universe. There are risks in meeting other civilizations no matter how intelligent they are. In 2010, Hawking reminded: We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
