We All Need Some.
verytime I turn around, it seems that there's something either catastrophic or dynamic happening somewhere in the world. The Olympic bombing. TWA Flight 800 crash. War. Floods. Famine. The Republican and Democratic National Political Conventions. Naaaah, scratch that last item. And the stunning announcement of life form traces in rocks from other planets.There are many things to watch unfold on a daily basis that affect all of us in ways we don't even realize, until it's right in our face.
All too often, we are consumed by what's going on directly in front of us. It's important to us, but in the scope of the community, nation, world or universe, it's fly shit in comparison. A juicy realization like that helps me put things into proper perspective. It humbles the soul and clarifies the direction quickly.
Years ago, when I worked in Madison Avenue advertising in New York City, I voraciously read The New York Times, Chicago Tribune, San Francisco Examiner and The Washington Post on a daily basis. Every day without fail. I kept up on what was happening in almost every situation around the globe. I felt good that I could discuss the nuances of corporate merger-mania, the subtleties of fine wines, technicalities of Formula One Racing, possibilities of nuclear war in the Gulf, hazards of insider trading, advances in medicene and so on. But dwelling on so many larger pictures helped me lose the more immediate view of my own personal world.
And one day it came crashing down. After clearing the debris and sorting through the remnants, it took almost a full year to rebuild what I once had. An important lesson learned: fly shit or not, take care of your immediate world of personal relationships first; the larger universe will do just fine without all the extra attention and somehow survive.
Some New Stuff.
With such a short attention span, America is constantly on the prowl for a new thing to capture its imagination and hold its fancy.
What will it be next? Hulahoops? Pet rocks? Athelete heros? Advertising slogans ("Where's the beef?")? Or will it be something really noteworthy and profound?
We've had quite enough of the dumb gimmicks, people and hype for a lifetime; in fact, several lifetimes. There's clearly something important afoot in the universe and we should be following it more closely than we now do.
Other Life Forms.
So far, popular reaction to NASA's announcement that its scientists have discovered evidence of life in a meteorite from Mars has been pretty positive. Only a few cynics have accused the space agency of a ploy for more funding. But that may change as the implications sink in. Last week's announcement is the biggest insult to the human species in almost 500 years, step two in a three-step process that will leave humanity totally humbled.
Ptolemy (second century) was the first and boldest in a long succession of spin doctors for the primacy of human beings. The whole universe, he postulated, rotated around us, with the Earth sitting at the center of heaven itself. Any marketing consultant will tell you that positioning is everything, and center-of-the-universe is hard to beat.
A Polish astronomer named Copernicus (1473-1543) rudely pointed out: Sorry earthlings, we spin around the sun, not vice versa. This might have made Copernicus unpopular, if he hadn't had the good sense to die the day his book went to press. His follower, Galileo Galilei (1564-1642), built a telescope and used it to piss in the soup even more. The sun, it seemed, has spots on it. Far from being the perfect furnace of heaven, it has a face covered with celestial zits. The moon is an uneven and pockmarked rock, and Jupiter upstages Earth by having multiple moons. The sky went from being a perfect clockwork centered on Earth to a fairly shabby neighborhood in which we were a minor resident.
This revelation was disquieting enough that the authorities of the time sought the only rational solution - they decided to burn Galileo alive if he didn't recant. Eventually Galileo did sign a decree saying that the Earth sat at the center of the universe, while muttering, "Eppur si moeve" ("But it still moves") under his breath. Giordano Bruno, a sort of 16th-century Carl Sagan, popularized these concepts without repenting, saying, among other things, that "innumerable suns exist. Innumerable earths revolve around those suns. Living beings inhabit these worlds." A soundbite like that would have gotten Bruno his 15 minutes of TV celebrity if he'd been around last week. But this was 400 years ago, so they roasted him to death instead.
Bruno's crime, like Galileo's, was to undermine the uniqueness of our planet, and by doing so, to threaten the intellectual security of the religious dictatorships of his time. People get cranky when you burst their bubble. Over time, advances in astronomy have relentlessly reinforced the utter insignificance of Earth on a celestial scale. Fortunately, political and religious leaders stopped barbecuing astronomers for saying so, turning their spits with human-rights activists instead.
But the hubris that makes us insist on a special role for humans and Earth didn't disappear: It just found other bases. Among the sciences, biology became the last refuge, for within its realm, Earth was still special. Life was the unique and sacred phenomenon of which we humans were the crowning glory. Consciously or not, mainstream opinion in biology--until last week--orbited around the essential mystery of life on Earth just as surely as the Ptolemaic view was lodged in the firmament. Only a few brave scientists violated the taboo and speculated on life beyond Earth.
Most visions of extraterrestrial life are actually steeped in human activity. The fictional extraterrestrials of Star Trek or a hundred other space operas are less alien than many of my neighbors. And funny, the ones running the place are mostly WASPish men. A galaxy full of these folks is no stranger than a Kiwanis club meeting: We have met the aliens, and they are us! Darker visions of life beyond earth support human supremacy in another way. After all, even the most monstrous and advanced alien foe can be vanquished by the likes of Sigourney Weaver or Will Smith. For that matter, those hapless aliens can't stay ahead of the doughty X-Files team without a conspiratorial collaboration with that least effective of all entities, the U.S. government.
Alien stories that are claimed as true are no better. Why Earth would be such a fascinating place for UFOs to visit is left unexplained. I mean, really: Roswell, N.M.? Inevitably, the UFO stories climax in the ultimate tribute to human ego. The aliens, it seems, have traveled umpteen billion miles so they can abduct us from our beds and have sex with us. I'm told that once you try a human, you never go back.
The NASA discovery suggests that life is probably a pretty ordinary phenomenon that occurs anyplace you give it half a chance. Earth isn't special. The alien life forms aren't special either. Instead of highly logical humanoids with pointy ears or other endearing characteristics, they seem to be a lot like simple bacteria. Should they invade, Will Smith can wipe them out with some Listerine.
When there's only one example of anything, its very uniqueness makes it special. Life on Earth was special because it was the only life we knew. In this case however, the dogma being shattered is based fundamentally on ignorance. Nobody knew whether there was life on Mars because, oddly enough, nobody had looked until now. The whole field of biology has rested precariously on a single data point--life on Earth. Last week, we got a second data point.
Research over the last 20 years has changed the scientific view of life. Researchers have found fossils, similar to those in the meteorite, in some of the oldest rock on Earth. There was evidence that life was present just as soon as the planet cooled and solidified. If that happened so quickly on Earth, why not on Mars, whose early stages of development were quite similar to Earth's?
A succession of discoveries has taught us about archeabacteria, very ancient and primitive single-cell organisms that live in the places you'd least expect anything to call home. They inhabit the near-boiling water of geysers in Yellowstone, and the even hotter water in volcanic vents on the ocean floor. They are in oil wells and the crevices of basalt deep within the earth. A basic tenet of biology used to be that the energy requirements of all living things are met ultimately by the sun--mainly through plants converting sunlight into more easily digestible forms of energy. The archeabacteria live far from any contact with the sun, subsisting instead on heat from the center of the Earth, nourished only by sulfur and other elements leaching from the rock. Some scientists have estimated that the sum of these tiny organisms spread deep within the Earth outweighs all the forms of life on the surface combined. Perhaps we surface-dwelling life forms are the exceptions--bizarre mutations of the normally deep-dwelling archeabacteria that populate the interiors of planets all over the galaxy. If the discovery is what it appears to be, the inside of Mars may still be full of them.
Looking ahead, we can anticipate the next frontier of activity. Sure, there may be life on other planets--if you call that life. But humans are still the only intelligent life--right? The wagons will circle to defend this last bastion of human conceit. Technology is only just beginning to let us search the skies for the telltale clues another civilization might offer. People who speculate on the odds can be either upbeat or quite discouraging depending on what ax they have to grind. But as with life on Mars, until you get a chance to take a look, how confident can you be one way or another? Maybe it's true that we're the only members of the big brain club, but I'll lay my bets with ET.
There's a consolation prize for humanity, though. The steady erosion of our claim to a special place in the universe has come with a steady growth in our maturity as a species. What greater intellectual puzzle can there be than dealing with nature on its own terms? Wallowing in a solipsistic world dictated by our own hubris isn't much of a challenge in comparison. Mankind is not special by virtue of our address in the universe, or what spins around us, or because life originated here. Slowly, but surely, we've been compelled to renounce the comfort of these beliefs. Our true distinction is the intellectual journey that brought us to this understanding.
Clearly, these are exciting times.
Brain freeze! Slurpee turns 30 this year. That's right, the slush-and-syrup concoction with the onomatopoeic name has been around longer than moon walks, The Brady Bunch and Lisa Marie Presley. Today's Slurpee is available in a rainbow of hues, in more than 15,000 7-Elevens (Southland Corporation) in 13 countries. I've never tried one, but I've heard from brave people who have, that they're... really awful.
