"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, ... every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam." -- Carl Sagan #PaleBlueDot #Sagan
