“We the people...




…of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.”

 “…hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” . . .

 “… And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes, and our sacred Honor.”

“Life is short, art is long, opportunity fleeting, experimenting dangerous, reasoning difficult.”
~ Hippocrates



Stars, Planets and The Meaningless Life
This morning you woke up, got yourself through the morning routine. You did this yesterday and you will do it again tomorrow. The days come and they go. You do your best. You try not to hurt anyone, try to be helpful. But sometimes — just sometimes — the fog of real and imagined urgencies parts. Staring across the abyss of your own brief time on this world, you wonder, “Does any of this matter? Does any of it matter at all?”

I had that experience and I am still reeling.

I was attending the American Astronomical Society‘s summer meeting, held this year in Anchorage. Being in Alaska this time of year, with its in-your-face mountain ranges and near continuous daylight, is enough to yank anyone out of the day-to-day. But the 21 hours of daylight and the brief bear encounter (hello Mr. Enormous Black Bear) were not the keys that opened the door to the abyss for me.
It was an image, a single picture.

I was sitting in a morning session on the Kepler mission. Kepler is a small space telescope designed to find exo-planets, alien worlds orbiting other stars. Kepler has been very good at its job.

Kepler discovers new planets by staring at stars and looking for tiny periodic decreases in their brightness. Dips in starlight can occur for many reasons but if they happen in just the right way, over and over again, then astronomers know they’ve observed a planetary transit, a planet passing across the face of its host sun (yes, this is exactly what happened with Venus a few weeks ago).

Once the existence of the planet is established, astronomers can extract a cornucopia of information from the data. Using Kepler (and other observations) astronomers can nail down the size of the planet’s orbit, its mass, its temperature and, sometimes, its density. The light that glances through its gaseous perimeter can even be used to determine the characteristics of the alien planet’s atmosphere.

More than 72 new worlds have been discovered by Kepler, with a few thousand more considered candidates. Many of these are gas giants like Jupiter. Some are so-called Super-Earths, planets a few times larger than our own. Astronomers are not yet sure of their structure. Some may exist as wholly liquid water-worlds (that is why density measurements matter). A number of the Kepler discoveries are true planetary systems, with up to 6 worlds orbiting the host star. But most important of all, a few of Kepler worlds are the size of Earth. They are, most likely, rocky worlds like our own.

The talks on Kepler were delightful and I drank in all the new science like a thirsty kid on a hot summer day. But none of what I learned pushed me out of my comfort zone and on to the ledge of my own mortality. Then, innocently, one of the speakers flashed an image related to the Kepler search strategy.

It showed the region of sky where Kepler would be looking for its planets. The probability of a planet and star lining up just right for us to see a transit is pretty low (just 0.5% for system like the Earth and Sun). That means Kepler has to stare at a lot of stars for a long time. To accomplish this the team keeps the telescope pointed at just one region of sky in the constellation Cygnus.

That patch night is not very big. Your hand at the end of your outstretched arm held up against the sky pretty much covers it. The speaker also showed an image of the galaxy and how much of it Kepler would be able to explore. It was a tiny wedge set against a vast galactic disk of stars and dust.

That is what did it to me.

Those images catapulted me out of the room, out of the meeting, out of the day. It felt as if the floor of all my routine concerns dropped out from under me: the bills I forgot to pay before I left; the car brakes that need fixing when I get back; my relationship with my cousins; my concerns about the election; my concerns about the cough that is taking too long to go away; all of it just deflated against one single and inescapable fact.

In a small patch of sky, in a small wedge of space, there are worlds out there right now. There are, most likely many thousands of them. These are places just like here, places where you can stand and look around. These are places with landscapes. Many of them are barren and lifeless, but some may show the colors that only a biosphere can create. Either way, they exist right now as I write these words.

I was reeling and shaken to the core. For that one moment all the meaning and concern I schlep from one day to the next evaporated before my small place in this very big galaxy.

It was dizzying and it was delightful. To be human is to suffer great and small. Even given all our blessings, we can still find ways to fill the day with urgent concerns. And when great suffering falls to us — health, economic, family — our horizons constrict to darkness. Thus, for me, anytime I can be lifted from the crushing sense that this is all there is, it’s a good thing. Anytime I can be reminded that there is more, so much more, than this mortal coil, it feels like a good thing.

One doesn’t have to search the Kepler archive to find that feeling. It can arrive in the form of art, poetry, your kids, laughter or just looking up and out. 


I hope you get a moment to do that today.  May you have a moment without meaning.

For my Little Urban Hipsters on this 4th.

May the words of a more reasonable seasoned soul counter the banality and predictability of today's rabid, quick triggered responses and  shallow, sluggish thinking.

While in Washington D.C. recently I asked a street vendor for directions. In broken English he asked, "You American and you not know where you going?" Despite his admonishment, he ultimately offered the directions. On this 4th of July, with uncertainty and incivility littering America's landscape and airwaves, lots of Americans are asking the same thing -- we're American and, yet, we don't know where we're going?
In the spirit of this 4th of July, as we celebrate our independence, our generation can and should offer up the directions. Conversation and civility are vital first steps.

Thank you Ms. Edna for this post.

"I served my country -- and they just want to take from it -- just take, take! Love it or leave it, that's what I think....some days I think I'd give everything I believe in -- everything I got, all my values, just to have my body back again, just to be whole again. But I'm not whole; I never will be, and that's -- that's the way it is, isn't it?" ~ Born on the Fourth of July?

May the United States become just another part of the world, no more, no less.

Thank you for the post.

My spirit lifts when I see your work. As for our national discourse as a young urban hipster, I say “good grief!”
