People have explored what they believe is the unknown since the beginning of time. People have not only discovered the unknown from visiting places, but from experimenting certain things relating to technology. From Christopher Columbus to Bill Gates you can see how many years of incoming discoveries there have been and are left. I personally would not devote my whole life to something that I am not %90 sure about and have faith in. I would have to make sure whatever I was spending my life on is valuable and not a waste of my time. Individual’s become devoted to this type of work because they find a topic/concept that interest them, come up with an approach to it, and then embark on it with all the faith they have. Quite exceptional things have came out of these explorations and I suppose horrid things have became of them as well.
