Stephen Hawking and the Aliens

An interesting event happened in the field of astrology that caught the world's attention. Stephen Hawking, the world-renowned British astrobiologist, supported the possibility of extraterrestrial lives and their potential threat to the Earth. My first response to this news was laughter. It's not that I think Hawking's theory is ludicrous (I know for sure that he is way more intelligent than I am), but it was comical that such a scientific minded person would talk about a topic that is easily dismissed as crazy should some other normal person talk about it. Responses vary in the blogosphere. But many seem to just laugh it away. David Ng talks about how the astrobiologists took the news--chuckle and then indifference. I think the 21st century citizens of the planet Earth is too busy focusing on the current Earth life to think about the extraterrestrials floating around the universe to find the next colony.
