The meaning of a dot

Clouds


At a photography club meeting last Saturday, a friend showed a dark, unusual image at the end of a presentation. I squinted at the screen, wondering what he could possibly be showing us, as Jeff asked the group if we recognized the photo. A few people did.

It’s Earth, he explained — our home. A “Pale Blue Dot” in the vastness of space. And then he read aloud a passage from astronomer Carl Sagan. It was one of the most powerful pieces I’ve ever heard.

We talk about more than photos at our montly gatherings — though the subject is certainly steeped in photography. Pale Blue Dot is a picture of Earth taken from 3.7 billion miles away. Captured in 1990, you may have heard of it — but I’ll confess I never had. (This upsets my scientist fiance, I’m sure.) In the days since Jeff showed us Pale Blue Dot, it’s been ricocheting around in my mind . . . as has Sagan’s passage from the book of the same name:


PaleBlueDot

“From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again 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.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, 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.

The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. 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.”


Home. Our little sliver of the universe.

Sometimes thoughts are too big to begin to contain them. This is probably one. But as someone always prone to asking too many Big Questions, it’s gotten me thinking — and thinking — and I felt it worth sharing.

Even on the bad days, even on the tragic days, even on the scary days . . . I’m glad we’re all here. Together.

  1. There are a couple of these that float by my eyes every now and again that make me stop and take inventory. There is another one called “Earth in perspective” that compares the size of the earth to other things in the universe. It is overwhelming but invigorating for the brain! Thanks for this!

  2. Thanks for sharing that passage with us. When I see pictures like that it’s just so hard to try and get it into my head that the tiny dot is our home.

  3. Amazing! I especially love (and agree with) your thoughts at the end. 🙂

    Btw, not to diminish Carl Sagan’s thoughts in any way, but really, we could bring Dr. Seuss’s Horton Hears a Who to mind, and the same wisdom is shared: a whole world on a tiny speck. Gosh, life is mind-blowing sometimes!

    So glad you decided to share this.

  4. I loved this, Megan! I have this picture and the write-up by Carl Sagan somewhere on my computer and I love stumbling across it again because it’s definitely one of those things that, as you said, just makes you think. Thank you for reminding me about this passage and I love the way it was introduced in your club!
