Billions suspended in a sunbeam
Today is writer and scientist Carl Sagan‘s 75th birthday. Carl Sagan is remembered for his remarkable ability to take scientific knowledge and present it in an elegant and comprehensive way to the broader public. An ability that I’ve truly come to appreciate as I’ve become more involved with communicating science. But it’s not just limited to that. Carl Sagan’s approach, along with that a few of his contemporaries, was a vestige of the approach by the natural philosophers who pushed forward the scientific revolution. These communicators not only put science in comprehensible terms for the public, but by describing the fragments together, they provided an avenue for science itself to become consolidated. They were concerned with epistemology, They posed questions the nature of human and his place in the universe, and with every question they shifted our views about who we are. Finally, they were pioneers who scoped the skies with spectacles of imagination to see not just what is, but what may be.
From my post two years ago: I just wanted to share a quote from Carl Sagan that I found tremendously inspiring when I was younger. Pale Blue Dot, displayed below, is the infamous picture of Earth, 4 billion miles out in space, at the edge of the solar system, taken by Voyager 1 in 1990, followed by Carl Sagan’s remarks on what this picture represents. I would like to share this because I find what Sagan presents to be both unsettling and moving on a fundamental level. Sometimes I find the existentialist parts of me, parts that desire to set the human definition and experience as encompassing all that is real and all that matters at odds with his perspective. At the same time however, I find myself awed by the profound truth in Sagan’s description of the entirety of humanity’s experiences on this planet.
“Our posturing, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves….
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. … There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”-Carl Sagan
