Thanks to the advances in astronomy, people nowadays have the ability to explore outer space, where was unreachable in the past. In light of this, some scientists are passionate and cannot wait to search the universe. However, other scientists argue that such activity is worrisome and that this may lead to appalling ramifications. In my opinion, people should be encouraged to explore the universe if any opportunities come and think that humans should have the spirit of adventures when involved in such a new area.
