Thank for the kind words @jaff8 - it's both the biggest and the smallest...
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam. - Carl Sagan
It is so interesting to see what a small dot could contain. I have never really imagine living outside the dot for a moment, have you thought of leaving? Maybe in some years time, we'll be chatting from different "worlds".
Maybe each colony will communicate via their own SMT ;)
