Some scientists believe that intelligent life forms may exist on other planets and some want to send message to contact them. Others think it is a bad idea because these life forms may be too dangerous. Discuss both views and give your own opinion. 20161013
Scientists in some space research institutes have been sending message to some corners of the universe since they were able to do that. Possible consequences of doing so, seemingly, have not been carefully analyzed yet.
Primarily, building connection with other intelligent species with humans' current technology does require incredibly high cost. This is to say, tremendous fund ought to be utilized for related technology research and establishment of some certain facilities instead of being used for solving some livelihood problems. Even though mankind were setting up connection with aliens who are living in a couple of light years away and are obviously less civilized with less advanced technology, with limited space technology that humans have currently we would be able do nothing further. Investing billions of dollars for saying hi to someone who might not understand at all is definitely not a wise decision.
Worse, unknown creatures that receive humans' greeting are more advanced and intelligent ones than inhabitants of the earth. What will happen at that time is more likely to be what people often see in science fiction movies nowadays. "White house is being attacked and Air Force One is shot down by missiles from unidentified flying objects". Intelligent species are not willing to co-exist peacefully or harmoniously with other creatures whose civilization apparently lags way behind. Their greed drives them use wars to make the earth their colony offering whatever they need from this planet. If that happened, humans would extinct and the only survivors would live their life in zoos of aliens.
As has been mentioned above, possible outcomes of sending message to unknown life in somewhere of the universe are what humans cannot afford or what we cannot accept. Therefore, space telescopes are not what we should spend money on, as paying for risks is never worthy.
