Space is a fascinating thing, our galaxy is incredibly vast. It is only natural human instinct to want to explore it. I believe that even though current scientific theory has difficulty with any kind of faster than light travel, it seems necessary for us to develop it to explore space, or visit possibly inhabited planets such as Keplar 22b. After we've solved the world's problems of course, we will likely begin to explore space. And therefore I think it is very important that we put together some kind of code of conduct, or set of laws, for how we should act if we find any kind of life out there, sentient or non-sentient. For example, if we were to travel to a planet (lets call it Alpha) and discover a planet with some incredible rich vegetation and animal life that we have never seen before, but no sentient life. We should make sure that whatever we do doesn't turn out like Columbus arriving in America. We do not should not disrupt anything that is already living in classic human fashion. We must preserve that planet's originality. Also with possibly an inferior sentient race, which would be likely as finding a superior or equal race. We should be very careful about revealing our presence or sharing our technology, because that could have some very destructive repercussions with that civilisation. We should effectively establish a 'Prime Directive', and for those who were thinking this sounded very inspired by Star Trek, you were correct. Thoughts?
