Stephen Hawkins warns over aliens Apparantly, Hawkins says that we should try to avoid contacting aliens as they can spot us and destroy our planet: http://news.bbc.co.uk/1/hi/uk/8642558.stm His inspiration comes from us, the fate of indigenous people of Americas in the hands of Europeans over 500 years ago. Being cautious against anything that we don't know is one thing, but trying not to attract something we are not even sure about it's existence is another thing. Are we unique? Are we alone? Apart from calculated probabilities and fantasies, we are desperate to prove if there is life out there. The consequences of this answer means almost everything for us. We might be discovered by any alien civilization without our effort. Would they have technological capacity to travel over here? If they have, what would they gain from our planet in terms of resources while there are bigger planets out there with better resources? To be honest, at the moment I find Hawkins's warning "dangerous" as it can easily be used as "fear production" against already insufficient public interest towards space exploration. Or maybe he secretly wants to raise public attention through fear... All in all, Hawkins' warning does not make any sense to me. What do you think? Should we really take him seriously and be quite? If you think we should, what is your supporting ideas towards this direction?
