Q: My friend and I (neither a crackpot in the ordinary sense) are in the middle of an ongoing argument that we'd like you to clear up. What is the possibility that we will someday communicate with life on other planets?
F.T., 7/19
I laughed out loud to read it. I spent the remaining afternoon answering as if this were itself an anonymous hello from deep space. Not that it took that long to compose my answer. I lingered, let myself down the luxury of unrelated alleys, the side paths research always opens up when one pays attention. The encyclopedia's country lanes.
A: Serious scientific estimates about the possibility of contacting life on other planets are based on the Drake or Green Bank formula:
N = R fg * nchz * f1 * f1 * f1 * L
where N = number of technical civilizations, R = rate of star formation, fg = fraction of stars with planets, nch2 = number of planets that are habitable, f, = fraction of these developing life, f1 = fraction of these developing intelligent life, f, = fraction of these with communications technology, and L = length of attempted communication. Of course, the equation says nothing about the values of the terms. Guesses for these are hotly debated, resulting in estimates for the number of intelligent civilizations in our galaxy ranging as high as 100,000 and as low as zero. After a quarter century of listening for messages from unknown galactic neighbors, all scientists have yet heard is a very imposing silence. Finding an intelligent signal would immediately present the enormous problem of how to respond. A two-line dialogue between sentient planets could take centuries; our great-great-great-grandchildren would have to remember what we said in order to make sense of the reply, assuming they could make human sense of nonhuman words. It is hard to say which would be more sobering: to hear someone answer our "Are you there?" with "Yes," or to learn that the whole experiment lies entirely in our hands.
Of course, the real question was not whether intelligent life existed elsewhere in the universe but whether there was intelligent life on Earth. Still, I delighted in my answer, knowing who was asking. He meant to let me know that I could hear from deep space if I wanted to. The two of them would enter and reenter my life, persistent, transposed, inverted, retrograde, spread through different voicings, announcing themselves in all contexts for every reason, sounding the capricious, cantabile motive as often as I let them.
Three answers in one day was a good haul by any standard; most people don't arrive at three definitive answers in a lifetime. And I had accomplished all three in the interstices, between the other duties demanded by one of the NYPL's sixty Brooklyn franchises. True, I had also fielded the routine phone calls: armchair investors too lazy to get off their A-ratings and read their own Value Lines, high school kids asking for a definition of S-O-D-O-M-Y (tape machine audible in the background), the bewildered citizens who'd crawled out of their paneled dens to request the names of senators. Those, plus the archiving, inventorying, and maintenance work, the box-piling tasks that monopolize existence.
But three for the fait accompli file: in that I took considerable fisherman's pride.
Back home, I found my POSSLQ — Person of Opposite Sex Sharing Living Quarters — hard at work on a campaign alerting the public to a major dental development that would, like the Great Wall of China, provide the long-sought security of Tartar Control. As I fell into the front room, Keithy asked cheerily, "So what'd she do all day?" For the first time all day, I was stumped. Coming at the end of the stack, this seemed less question than request for intimacy. And intimacy was no longer mine to give. I flopped on the couch, undid some buttons, and capitulated. The candy dish stood in for dinner. I listened to Keithy insult mankind for my amusement. "Looky here. You hate this photo? How about this text? Totally humiliating? Good. I think we've got a wiener, here."
Lying slack, I thought of something my mother said, the first and only time she ever came out from Indiana to visit me. "This is not a city," she sneered in utter distaste for the place I'd chosen as home. "This is a country. A world." I was new here myself then, and thought she was right. Precisely the reason I had come here to live. A country, a world, large enough to lose oneself in. Now I roused myself enough to look out of the front picture window onto the East River, a stunning view that cost Keith and me half our income. On the far side, the fanfare of lights, the community that was slowly killing us. From where I lay I could see my mother's error. Nothing stood between me and the insane compression of midtown. No moat, no ad-campaign misanthropy could shut out the runaway numbers, the gang rape of the place.
Keith watched with me as the lights came on — Japanese-lantern bridges, street pearls, block skyscrapers that flared as if half the executives in the world worked late. He burlesqued the view, the most overwhelming display of scale that the race has yet assembled, dropping into his smarmy announcer's voice. "Experience the charm of Halogen." He did it to relax me, but I hated him for it all the same. I picked a block on this side of the river and populated it: two souls of unfortunately high intelligence sitting alone among precision machinery, watching over the magnetic data by night, arguing, as if it mattered, over whether we were the only going show in the universe. Clear-faced Todd, obvious closet romantic, held out for other intelligent life, while his night-shift companion, a generation older, told the boy to stop kidding himself. Imagining this insignificant dialogue in this uncounted corner of a sprawl too dense to map adequately, I reversed my mother's terrified conviction about the city. This was not a world. It was an abandoned colonial outpost, a private conversation. Only the buildings were big.
Fear of scale came over me: if I lay there any longer, every uncountable block in these awful islands would become inhabited. Clicking heels and chanting "There's no place like Elkhart" was no longer an option. I had to do something quickly — leave some entry on this July 15—or lose myself in the cycle of torn-off days. I lifted myself like a wet foal. Without explaining, I left Tuckwell still talking to himself, in lone possession of the front room. Shutting the door with a furtive thump that echoed badly down the months ahead, I locked myself in our bedroom. I picked up the receiver and dialed the number Todd had given me. A number I'd filed for easy retrieval.
The half of the night shift I could claim some knowledge of answered. Franklin professed to be glad I'd called. "You'll never guess what has happened. I confronted Dr. Ressler with your evidence. He was greatly impressed." I waited for him to go on. Ten seconds, an epoch over the phone. How do messages travel simultaneously over phone wires without colliding? It occurred to me that while wires did not technically carry any information when both parties were mute, passed silence nevertheless required a phone.
I looked for anything to fill the gap. "I've contacted your extraterrestrials. If you come by the branch—"
"Maybe it's time you visited us here." He gave me the address, one that took my breath away. A dozen buildings from the branch. I knew the exact place, a brick turn-of-the-century warehouse that gave away nothing of its contents. The city, big, uncountably massive, had a way of turning viciously small, like Nauru, digging itself into disappearance. A range of adjoining neighborhoods that refuse to collect. Ten million neighborhoods of one. It is not skyscrapers; it is the bottoms of deep troughs, deeper than the carved canyons out west, cut from harder stone.
