My truck is a 1998 Freightliner with four hundred thousand miles on it. It runs, mostly. The transmission slips in third gear. The AC stopped working in 2009. The seat has a rip in it that I have never fixed because fixing it would mean admitting that I notice it, and I would rather not admit that.

I drive from Toledo to Detroit every week. Auto parts. Heavy stuff. The kind of cargo that makes your lower back hurt in ways that painkillers cannot fix. I am forty-four years old. I have a CDL. I have a divorce behind me. I have a daughter I see every other weekend. I live in a mobile home on the edge of a town in Ohio that used to be a steel town and then a manufacturing town and then nothing.

Main Street has three open businesses: a dollar store, a payday loan place, and a pawn shop. The rest of the storefronts are boarded up. The river nearby is the color of rust. The sky is grey most of the year. The people who live here are the people who cannot leave.

I am one of them.

* * *

My landlord, Mister Ray, calls me on a Tuesday. He is a Black man in his sixties who owns the strip mall where my mobile home sits. He has lived through the decline of the town. He has seen the factories close, the people leave, the hope drain away. He is cynical but not bitter. He has survived by not caring too much about anything.

"Tom," he says. "There is something in your garage. I don't know what it is. You better come look."

I drive home. My mobile home is small: one bedroom, one bathroom, a kitchen that smells like old coffee. The garage is a detached structure behind the mobile home, a concrete slab with a roll-up door that sticks half the time.

I open the door. In the center of the concrete floor, there is a silver sphere. Perfect. Smooth. About the size of a bowling ball. It does not reflect the light. It absorbs it. I stare at it for a long time. I poke it with a broom. It does not move.

I call Mister Ray. "What is this?"

"I don't know. I was coming to fix your gutter and I saw it and I thought you should see it."

I call the number he gave me, the number of the government guy who says his name is Agent Kim. She arrives in a black sedan forty minutes later. She is young, maybe thirty, efficient, dressed in a suit that costs more than my truck. She looks at the sphere. She looks at me.

"This is an alien probe," she says.

I nod. "Okay."

"We need someone to guard it. You will be paid."

I think about my daughter. About my bad knee. About the fact that I have been driving trucks for twenty years and have nothing to show for it.

"How much?" I ask.

She gives me a number. It is more money than I have seen in a year.

"I will do it," I say.

* * *

I sit in a metal chair in my garage, watching the silver sphere. I bring a television. I bring a thermos of coffee. I bring a pack of cigarettes. I sit there for months, living in my mobile home, eating microwave dinners, watching the sphere.

Agent Kim visits once a week. She brings me papers to sign and information to read and questions to answer. She is efficient but uncomfortable. She represents the bureaucracy: people who are doing their jobs and trying not to think about the implications.

She tells me about the Dark Forest Theory. About the alien fleet. About the Broadcast. I listen, not entirely understanding.

"So you want me to guard this thing," I say. "And if something happens to it, everybody dies."

"Yes."

"And if I press this button," I point to a red button she gave me, "everybody dies anyway."

"Yes."

I think about this. I think about my ex-wife, Elena, who left me because I didn't want anything more from life. I think about my daughter, who calls me once a month and asks when I am going to do something with my life. I think about Mister Ray, who has watched his town die one business at a time.

I am just a truck driver, I say.

Yes, she says.

* * *

Elena and I were married for twelve years. She is an astronomer at a small university in Pennsylvania. We met at a conference. She was presenting a paper on stellar spectra. I was there because I had just bought a telescope and I wanted to learn more about the stars. She saw me in the audience, asking questions that were too simple for the room but exactly right for her.

She said yes to dinner. She said yes to marriage. She said yes to having a family. And then, twelve years later, she said no to staying.

"You don't want anything more from life," she told me, packing a suitcase in the bedroom we shared. "You drive your truck. You watch your TV. You go to work. You come home. You do not want more."

I did not argue. She was right. And the terrible thing is that I was not ashamed of it. I was content. I was content to drive trucks and watch TV and live a small life in a small town. She was not content. She wanted to reach the stars. And I could not give her that.

She left. I stayed. We talk once a month. She tells me about her work. I tell her about the truck. We are polite and distant and kind, in the way that people who loved each other once are kind when they can no longer love each other.

* * *

I grow older. My knee gets worse. The government finds a replacement. A woman named Chloe Hart, who works at the trucking company I drive for. She is in her thirties, kind, practical, and she volunteers at a shelter in Cleveland on weekends.

When I find out she has been chosen as the new guard, I go to see her at the trucking company office. She is sitting at her desk, looking at papers. She looks up when I enter.

"Tom," she says. "How are you?"

"I am fine. I heard about you."

She nods. "I agreed to it."

"Why?"

"Because it is the right thing to do."

I look at her. I think about saying something. Warning her. But I realize that Chloe is not like me. She is like Elena: someone who reached for something larger than herself. Someone who believed that doing the right thing mattered, even when the right thing was hard.

"It is alright," I say. "You will do fine."

* * *

The transition takes place on a Friday afternoon. Chloe comes to my garage in a government car. She is wearing jeans and a sweater and a look of determined concentration that I recognize because I have seen it on my own face in the mirror a thousand times.

She sits in the metal chair. I stand beside her. The silver sphere sits between us on the concrete floor, perfect and smooth and dark.

"This is it?" she asks.

"This is it," I say.

She looks at the sphere. She looks at the red button. She looks at me. "What do I do?"

"You just sit here. Watch it. Make sure nothing happens to it."

"And if something happens?"

I think about the answer to that question. I think about the alien fleet. I think about the Broadcast. I think about the universe, vast and dark and indifferent, and the fact that a truck driver from Ohio and a volunteer from Cleveland are the only things standing between humanity and extinction.

"If something happens," I say, "you press the button. And then everything happens."

She nods. She understands more than I give her credit for.

I walk home. I sit on the steps of my mobile home. Mister Ray walks by.

"Rough day?" he asks.

"Every day is a rough day," I say.

He sits down beside me. "You know one thing? I spent my whole life in this town. Saw it go from something to nothing. And you know what I learned?"

"What?"

"Nothing matters. And that is a good thing. Because if nothing matters, then you can do anything."

I think about this. I think about the universe. About the Dark Forest. About how every civilization is a gunman in the dark, and how I am just a truck driver with a bad knee and a silver ball in my garage.

The sun sets. The sky turns grey. The river flows, the color of rust. The stars come out. The dark forest is dark.

And I live another day.

* * *

On the day the Two-Dimensional Ribbon arrives, I am driving a load of auto parts from Toledo to Detroit. The radio is playing. Some country song about a truck and a woman and a road that goes on forever. My knee is hurting. The transmission slips in third gear.

I notice it first as a change in the sky. A silver light, like a ribbon, stretching across the horizon. It moves slowly, gracefully, like water flowing downhill. It touches the landscape and the landscape becomes flat. Not metaphorically. Literally. The hills, the trees, the roads, the buildings, all compressed into two dimensions.

I pull over. I get out of the truck. I watch the ribbon move across the Ohio countryside. It flattens a field. It flattens a road. It flattens a town. The people in the town, I assume, are flattened too. I do not think about that for long. Some things you do not think about for long.

Agent Kim calls me. Her voice is calm. Efficient. She has done this before, in her mind, even if she has never done it in reality.

"Tom," she says. "I need you to do something for me."

"Okay."

"I need you to press the button."

"The red button?"

"The red button."

I look at the red button in my pocket. I have carried it with me for two years. I have never used it. I have never even pressed it to test it. It is just there, a small red circle of plastic, waiting.

"I am a truck driver," I say.

"I know."

"I drive from Toledo to Detroit every week. Auto parts. Heavy stuff. The kind of cargo that makes your lower back hurt in ways that painkillers cannot fix."

"Tom."

"I am forty-four years old. I have a divorce behind me. I have a daughter I see every other weekend. I live in a mobile home on the edge of a town that used to be something and then wasn't."

"Tom, please."

I close my eyes. I think about Elena. About Chloe. About Mister Ray. About the silver ball in my garage, which is now probably flat too, a two-dimensional silver circle on a two-dimensional concrete floor.

I press the button.

The Broadcast goes out. Every star, every galaxy, every hiding civilization in the universe: I tell them where Earth is. I say: here we are. We are truck drivers and astronomers and volunteers and landlords. We are the people who cannot leave. Come and find us.

The ribbon passes over me. The sky goes flat. The road goes flat. The truck goes flat. The country song on the radio plays until the radio is flat, and then the music is flat too, compressed into a single plane of sound and silence and everything in between.

And I am flat. And nothing matters. And that is OK.
