“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,
where 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 young couple in love, every mother and father, hopeful child,
inventor and explorer, every saint and sinner in the history of our species lived there
-on a mote of dust suspended in a sunbeam."
--Dr. Carl Sagan
"The Pale Blue Dot"
We look around every day and see crowds. Cities alive with bustling humans going about their business. Freeways jammed with cars, trucks, and motorcycles, always going somewhere. Even outside the urban areas, it's still a crowded place, chockablock with trees, plants, animals, and insects. We tend to think of earth as a place running out of space.
Then something happens. A picture, always worth a thousand words, appears before us, tapping that sense of awe within and putting the percolating details of life in proper perspective.
This week, NASA leaked the very first pictures of Earth taken by the Cassini space probe, currently orbiting the ringed planet Saturn. At first you don't see it. Then, you do. A small bluish speck glowing by reflected sunlight against the empty backdrop of the universe. Your mouth falls open just a bit; maybe you take an involuntary gasp.
Astronauts and Cosmonauts have all talked about that magical moment of perspective when they first see their home planet from space. Suddenly, a world and its people once thought of as being bisected and divided by borders and boundaries is seen, not as a collection of geopolitical states and races, but as one organism, fragile and alone, hanging in a vast ocean of...nothing.
It is a humbling thing to behold. We, as a human race, tend to think highly of ourselves, of our place in the universe. To be fair, there are those of us who do produce large splashes in our particular pond. But we have always considered us to be favored by creation, what- or whom-ever the author. In our early history, earth was thought to be at the center of the universe, that the sun orbited around us instead of the other way around. When Copernicus first proposed the idea of a sun-centered system, he was brutalized by the religious authorities of the day, who thought he was somehow insulting God.
The truth is that the earth and her teeming billions are but one planet in an otherwise unremarkable solar system floating around the galaxy, not close to the busy center, but shunted off to the side. Even our galaxy, vast and seemingly crowded with hundreds of billions of stars is but one of hundreds of billions floating throughout the known universe.
