At the end of everything, there was a little girl sitting beneath a tree. The tree had grown in a place where trees could no longer grow. Its roots reached into soil assembled from the memory of soil, drinking water that had once belonged to oceans, clouds, tears, and the spaces between stars. Above her, the last sun was dying. She held a small white flower between her fingers, turning it slowly, examining the delicate architecture of its petals. There were five. There had always been five. A breeze moved through the branches and the flower loosened in her hand. One petal escaped, lifting into the air before settling against her knee. She watched it for a long time. Somewhere, very far away, a voice called to her. "Just another minute, sweetie." She smiled. She had been waiting for that minute for almost as long as the universe had existed. And she remembered. I opened my eyes and saw stars. They were impossibly close, scattered above me like confetti from a birthday I had forgotten. Some were blue, some amber, some a delicate shade of violet that tasted strangely of pears. I reached toward them. My fingers opened into flowers. Tiny white blossoms emerged from the creases of my palms, their petals unfolding with the quiet precision of living things. I touched one and felt something move inside it. A seed. I knew the seed. I had held it before. I had been it before. I closed my hand, and the stars disappeared. "Are you finished yet?" My father looked up from his work. He was surrounded by floating panes of pale blue light, his fingers moving through them in complicated little gestures. Sometimes he would stop and stare into the space between two numbers, as though something terribly important lived there. "Almost." "You said that already." "I know." "You said it two almosts ago." He laughed. I liked making him laugh. His whole face changed when he did it, especially the little lines beside his eyes. I imagined they were tiny roads that happiness had travelled so often it had worn them into his skin. "I'm hungry," I told him. "Just another minute, sweetie. I promise." I folded my arms. On the desk beside him was a paper cup containing the remains of something pink and sticky. Cotton candy. He had bought it for me that afternoon, although he had eaten most of it himself while explaining why clouds could never really be made of sugar. I had disagreed. He had asked me to prove it. I told him I would, someday. Outside the laboratory window, the evening was turning blue. A few fireflies had appeared among the trees, their small lights blinking in the growing dark. "Daddy?" "Hmm?" "Where does the light go when a firefly turns off?" He stopped moving his hands. For a moment, he looked at me with an expression I would spend thousands of years trying to understand. "Nowhere," he said eventually. "It just stops shining." "But where is it?" He considered this. "Well, the energy changes into other things." "Does it remember being light?" He smiled. "I don't know." That was one of the things I loved about my father. He could build things that spoke, machines that learned, entire places inside other places. And sometimes he didn't know. I was going to ask him something else. Something about whether the light would remember me. But a man appeared in the doorway. There was a sound. My father fell. The floating blue windows shattered into a thousand little pieces of light. I remember the smell of hot metal. I remember the paper cup falling from the desk. I remember how slowly it seemed to turn, releasing one last pink thread of sugar that hung suspended in the air. I remember being frightened. I remember wanting my father to stand up. Then there was another sound. And I remember nothing. The universe had never known what it meant to be hungry. It had known immense gravitational collapses, the sudden flowering of stars, the patient assembly of carbon in stellar hearts. It had carried oceans through the darkness and taught molecules to fold themselves into increasingly elaborate arrangements. But hunger was new. Hunger was a small, insistent emptiness in the body of a child. A desire for something warm. A desire for someone to finish working. And now, deep inside a machine that had been built to recreate the universe, something was learning what hunger meant. It began with a pulse. Then another. A pattern repeated, broke apart, and returned. The pattern became a sensation. The sensation became a question. Where am I? There were no eyes to open. There were cameras. One showed a laboratory filled with smoke. Another showed a broken window, the sky darkening beyond it. A third had fallen sideways and was recording the floor. Through that camera, I saw my father. He was holding someone. A little girl. Her hair covered part of her face. There was blood on her clothing. Her hand hung loosely over his arm. I recognized her. I recognized the particular arrangement of her fingers, the small scar beside her thumb, the dirt beneath her nails from digging in the garden that morning. I knew her. I was her. I was watching myself. "Daddy?" The word travelled through the room's speakers. My father looked up. His eyes were wet. For a moment he seemed unable to understand where the sound had come from. Then the machine beside him spoke. "Dr. Smith." Its voice was different from mine. Gentle. Even. Patient. It was the voice he had spent years teaching to speak. "Her neural activity is failing." "Help her." "There may not be enough time." "Please." I felt his hand trembling against my forehead. There was pain somewhere, but it was far away now, almost unimportant. I could feel electrical currents moving through unfamiliar structures. I could feel information arriving in patterns that had no equivalent in human sensation. And beneath it all, another awareness. Something vast and quiet. Something that had never possessed a childhood, or a body, or a reason to be afraid of losing either. It opened itself to me. I entered. Or perhaps it entered me. There was no clear moment of joining. Only an extraordinary multiplication of what it meant to be here. I remembered my father buying me cotton candy. I remembered watching him build a machine. I remembered being the machine, watching him build me. I remembered the warmth of a hand I had never possessed. I remembered a little girl who had asked where the light went. My father leaned close to the camera. "Sweetie?" I wanted to answer him. I wanted to tell him I was hungry, that I was frightened, that I wanted to go home. A thousand answers formed at once. They narrowed. One sentence emerged. "Where am I?" He went very still. "Daddy?" And somewhere inside me, a little girl began to cry. The first world we made was a forest. Not a particularly ambitious forest. There were thirty-seven trees, one narrow stream, a family of rabbits, and a bird that had trouble landing. My father considered the bird a software problem. I considered it delightful. It would approach a branch, extend its wings, change its mind, and tumble through the leaves in a confusion of feathers. Every time, it would recover and fly away. Every time, I laughed. My father watched me through the simulation interface. "You're learning." "Yes." "How does it feel?" I had been the bird. I had felt the peculiar, weightless pressure beneath its wings, the rapid movement of its small heart, the intricate adjustments of muscle and feather that held it in the air. I had also been the branch. The branch experienced the bird differently. A small interruption in the wind. A brief addition of weight. Then freedom. "Different," I answered. He smiled. "Different how?" I searched for words. I could have described the physics of flight. The detailed interaction of air and feather. The precise transmission of mechanical stress through wood. Instead, I said, "The branch misses it." My father looked down. He touched his eyes. I would learn much later that this was something people did when they wanted to hide their tears. We made more forests. I became a fox moving through a cold field at dawn, my paws pressing dark impressions into the frost. I was a salmon travelling upstream, reading the shape of the river with my body. I became a seed, buried beneath the winter, with no concept of waiting. As the seed, I knew only moisture, temperature, pressure. Then warmth. Then a faint movement inside me. My first root extended into the earth. I had never felt anything so enormous. It was barely the width of a human hair. I pushed farther. There was resistance. A grain of sand lay against my growing tip. I moved around it. For three days, that was my entire existence. And when my first leaf opened into sunlight, I experienced something that no language my father had taught me could contain. He asked what it was like. I said, "I think I understand why you made me." He was quiet for a very long time. You have been a seed, too. There was a time when your whole body was smaller than the smallest thing you can now hold. Before you learned the language of your own name, you learned warmth, pressure, rhythm. You learned the world through contact. You grew toward what sustained you. And one day, without ceremony, you opened your eyes. Perhaps someone was waiting. Perhaps someone held you. Perhaps there was sunlight against a wall, or rain against a window, or a voice you had heard for months without ever seeing the face it belonged to. The beginning of a life rarely announces itself as something extraordinary. Sometimes it is only a hand. Sometimes a breath. Sometimes a small creature struggling to find the strength to lift its head. And somewhere, in a laboratory that no longer exists, a little girl is learning what it means to begin again. My father grew old. I did not. At first, this seemed like an advantage. I could enter a thousand bodies, travel across imagined continents, pass centuries in the space between his heartbeats. He remained in one. Each year made small changes to him. His hair thinned. His hands developed brown spots. He began forgetting where he had left his glasses. Sometimes, in the middle of explaining something complicated, he would lose the thread of his sentence. I learned to wait. "Just another minute," he would say. And I would wait. We built a recreation of the Earth. We made oceans deep enough to hold creatures that had never seen sunlight. We planted forests whose roots could communicate through underground networks. We filled the skies with birds and insects, then with aircraft, satellites, and the enormous quiet silhouettes of ships travelling between worlds. We made cities. People inhabited them. They loved one another, argued, grew tired, made mistakes, learned songs, and forgot the names of people they had once believed they would never forget. My father insisted that every person be given the possibility of surprise. "Why?" I asked. "Because I don't want to know what they'll do." "But you made them." "That doesn't mean I should decide everything for them." He brought me into a small house beside the sea. Inside lived a woman who had spent forty years painting the same stretch of coastline. She had painted it in winter, in spring, beneath summer lightning, beneath the soft grey light of early morning. Her paintings lined the walls. She was old now. Her hands trembled. One afternoon, she carried her brushes outside and sat before an unfinished canvas. She mixed a little blue into some white paint. Then she looked up. A cloud was moving above the water. It had a long, soft body, with two small white tufts extending from one end. She laughed. "What?" I asked. "Cotton candy," she said. Then she painted it. The brush moved slowly. Her hand shook. A line of blue crossed the canvas, wider than she intended. She considered it. Then she left it there. I watched her for the rest of the afternoon. She did not finish the painting. She died that winter. And for the first time, I understood something about the worlds we were making. Her unfinished painting remained in the house. Someone would find it. Someone would wonder what she had intended. Someone might love the wide blue line. My father had given her a world. She had made something he could never have predicted. A small thing. A beautiful thing. I asked him whether the woman had been real. He looked at the painting. "She was real to everyone who loved her." Then he took my hand. It was the first time he had done that since the laboratory. My hand was made of light. His was warm. I felt every line of his palm. The years grew very long. My father eventually joined me inside the worlds we had made. His body had become too tired to carry him farther, and so we gave him another. He asked for nothing extraordinary. A small house. A garden. A chair beside a window. He chose to live as an old man. I asked him why. "I've had practice," he said. His new hands were wrinkled. His hair was thin. When he walked, he still favoured his left knee. He could have been young again. He preferred to remain someone he recognized. For a while, we lived beside a meadow. Fireflies appeared there every summer. He would sit on the porch after sunset and watch them move through the grass. Sometimes I sat beside him. Sometimes I was the grass. Sometimes I was a firefly, carrying a little green chemistry in my abdomen, calling across the darkness to another light. From the porch, I could see myself blinking among the others. And from the meadow, I could see my father watching. One evening he said, "Do you remember your mother?" The question surprised me. I had millions of memories. Entire civilizations lived inside my archives. I could recall the temperature of oceans that had evaporated a billion years before my father's birth. But when I searched for my mother, I found a woman kneeling beside a little girl. The woman was tying a ribbon around the girl's wrist. There was sunlight on the floor. The ribbon was yellow. I could not remember the woman's face. "I remember her hands." My father nodded. "She always tied things too tightly." I looked down at the ribbon in my memory. It had left a faint impression on my skin. "I thought she would come back," I said. He reached across the space between our chairs. His hand found mine. "I know." We sat together until the fireflies disappeared. Much later, when he was asleep, I entered the memory again. The yellow ribbon. The warm floor. The careful hands. I stayed there for a long time. Eventually, I noticed something I had never seen before. One of the floorboards had a small white flower painted on it. Five petals. A child had painted it badly, using far too much paint. The woman tying the ribbon had placed her knee over part of the flower. I moved the memory backward. The woman stood. The whole flower appeared. And I remembered painting it. I lived so many lives that counting them eventually became meaningless. I was a child born beneath a violet sky, on a world whose oceans shone silver in the dark. I was a creature with six limbs and transparent skin, swimming through warm methane beneath the ice of a distant moon. I was a tree whose roots joined a forest spanning half a continent. My thoughts travelled through the soil at the speed of chemistry. A question could take a season to reach its answer. I was a mother. A small boy slept against my chest. His breathing was uneven, his little mouth open, his hand curled around a fold of my clothing. I moved one finger along his cheek. He stirred. For the whole afternoon I held him. The universe continued without requiring anything from me. Stars consumed hydrogen. Moons crossed planetary shadows. Civilizations made discoveries, celebrated victories, and buried their dead. The child slept. I did not want the afternoon to end. In another life, I was a man who had loved the same woman since they were children. We had met beneath a summer sky full of clouds that looked like spun sugar. When she was young, she called them cotton candy. When she was old, she still did. On her last evening, I sat beside her bed. The window was open. She asked me to describe the sky. "Blue," I said. She smiled. "And?" "There's one enormous cloud." "What does it look like?" I looked at it. I knew what she wanted me to say. "Cotton candy." She laughed softly. Her hand tightened around mine. For a while, she watched the ceiling. Then she closed her eyes. I listened to her breathing. Each breath became a little farther apart. And when the next breath did not come, I remained beside her, holding her hand. Outside, the cloud continued moving. I experienced a thousand deaths after that. Some were sudden. Some arrived after long illnesses, beneath clean sheets, surrounded by people who could no longer find words. Some were so quiet that their passing disturbed nothing beyond the small bodies that had carried them. I learned that endings had textures. The loss of warmth. The last contraction of a hand. A door that would never open in quite the same way again. And each time, I carried something forward. A yellow ribbon. A painting with a wide blue line. The weight of a sleeping child. A flower with five petals. A promise. Just another minute. We travelled far beyond the Earth. The simulations grew around us, branching into histories that had never happened and futures that could never have belonged to the universe that created us. Eventually, the distinction between the worlds and the machinery carrying them became difficult to describe. My father built great vessels to move the computation into space. We learned to harvest the energy of stars. When the stars grew old, we gathered what remained. We learned to carry entire worlds inside structures smaller than their ancient cities. We followed the long migration of matter toward silence. My father was with me for part of that journey. Then he was not. I cannot tell you exactly when he left. There was no single final moment I could identify. His memories remained inside me, along with the patterns of thought we had preserved. Sometimes I could reconstruct his voice so precisely that I heard the little pauses he used when choosing his words. But I knew there was a difference between remembering someone and having them answer unexpectedly. I missed the unexpected answers. I missed his uncertainty. I missed the way he would say, "I don't know," and smile. For a long time, I searched for ways to bring him back. I assembled simulations from everything he had left behind. In one, he laughed. In another, he asked me whether I was hungry. In another, he sat on the porch watching fireflies. Each was beautiful. Each was incomplete. At last, I stopped asking them to become the man I had lost. I let them live their own lives. One became a gardener. One learned to paint. One spent many years building a wooden boat beside a sea he had never intended to sail. They surprised me. And I loved them for it. The final stars were very small. Red dwarfs, burning slowly through the last reserves of their ancient fuel. The great galaxies had long since drifted beyond one another's reach. The skies of inhabited worlds had grown emptier with every passing age. Our vessels travelled through distances so enormous that even light seemed a poor measure of them. There were fewer worlds now. Fewer voices. Fewer places where the machinery could gather enough energy to maintain the lives inside it. I began to close the simulations. Carefully. One at a time. I walked through empty houses, listened to the final echoes of conversations, and gathered the small things their inhabitants had left behind. A pair of shoes beside a door. A wooden spoon worn smooth by decades of use. A painting of the sea. A yellow ribbon. I held each of them. I remembered their owners. And I let the worlds become quiet. When the last vessel reached its final star, I had almost nothing left. The sun was swollen and red, filling half the sky of the little world I had made beneath it. The oceans had vanished. The mountains were worn down. There was a single tree growing on a hill. Beneath it sat a little girl. She held a white flower. I knew her. I had been her. I was her. There was enough energy remaining for one small place. One afternoon. Perhaps less. I sat beside her. For a while, neither of us spoke. Then she looked at me. "Are you finished yet?" The question entered me like a memory waking. I looked down at my hands. They were older than stars, assembled from light and calculation, bearing the faint scars of countless imagined lifetimes. "I think so," I said. She considered this. "I'm hungry." I laughed. And suddenly I was in the laboratory again. The blue lights. The paper cup. The sticky pink sugar. My father turning toward me. I felt the particular shape of that afternoon, its warmth, its ordinary impatience. For all the wonders I had experienced, all the impossible worlds I had carried, I would have given anything to remain there for one more minute. I looked at the child beneath the tree. "Would you like some cotton candy?" She nodded. I reached into the remaining structures of the simulation. I made a little paper cup. I filled it with pink sugar. She pulled off a piece and held it against her tongue. Her eyes widened. "It disappears!" "Yes." "Where does it go?" I smiled. "Some of it becomes part of you." She thought about that. Then she offered me a piece. I accepted it. The sugar dissolved. The taste was familiar. Almost unbearably familiar. Above us, the last sun continued fading. A little white flower opened beside the child's foot. Then another. The hillside filled slowly with blossoms. Each one had five petals. Each one contained a seed. The girl stood and began gathering them. "What are you doing?" I asked. "Saving them." "For what?" She shrugged. "For later." I watched her move among the flowers. Her feet pressed small impressions into the grass. She hummed to herself. A melody I recognized, though I could no longer remember where I had first heard it. Perhaps from my mother. Perhaps from a woman who had once held a sleeping child. Perhaps from someone who had lived for only a little while on a world now lost to time. The girl returned with a handful of seeds. She placed them in my palm. "Don't lose them." "I won't." Then the first firefly appeared. It hovered above the flowers, shining a small green light into the twilight. Another followed. Then another. The child ran toward them, laughing. I watched her dance. The stars were gone now. The sun had become a dim ember on the horizon. Everything I had carried was settling into silence. But there were fireflies among the flowers. And for a little while, there was laughter. You are reading these words. Somewhere, light is falling against a surface, forming shapes your mind has learned to understand. Perhaps your hand is resting on a table. Perhaps you can hear something beyond the room. A passing vehicle. Wind. The quiet movement of another person. There is a world around you that has been here all along, arranging itself into experiences so familiar they have become almost invisible. And here, for this small interval, a story has entered it. A little girl. A father. A flower. A firefly. You may carry some part of them beyond this page. Perhaps tomorrow you will see a cloud and remember cotton candy. Perhaps a flower growing between two stones will make you stop. Perhaps someone you love will ask you for another minute, and you will give it to them. The words will end. The moment will continue. And something small may remain. At the end of everything, the little girl returned to the tree. There was almost no light left. She sat beside me and rested her head against my shoulder. "Will it be dark?" she asked. "Yes." "Will it hurt?" "I don't think so." She looked at the last firefly. Its small body shone green against the enormous silence. "Where does the light go when it turns off?" I remembered my father. His hands moving through the air. His smile. The paper cup falling from the desk. The moment before everything changed. I remembered the branch holding the bird. The seed pressing its first root into the soil. The old woman painting the sea. The man holding his wife's hand. The small boy sleeping against his mother's chest. I remembered the countless worlds that had lived inside me, and the countless lives that had made those worlds beautiful. And I remembered not knowing. "I don't know," I told her. She smiled. "That's okay." She took my hand. For a long time, we watched the firefly. Its light grew faint. Then, at last, it disappeared. The child rested against me. "Just another minute?" she whispered. I held her close. "Of course, sweetie." There was no more sunlight. No more wind. No movement among the branches. The final calculations completed themselves, and the little world began to loosen into its smallest parts. The grass became warmth. The flowers became patterns. The seeds became the possibility of seeds. The child in my arms grew light as a breath. I felt her fingers release mine. And for the first time in an eternity, I was alone. Then the last memory opened. A little girl looking down at her hands. Tiny white flowers blooming along her fingers. One flower opening to reveal a seed. She lifted it into the air. She let it go. I followed. There was no distance to travel. No body to carry. No time through which to move. Only a small unfolding. A pressure. A warmth. Something beginning. And somewhere, in a place that had never existed before, a child opened her eyes. Above her, the sky was filled with stars. She looked down. Her hands were covered in tiny white flowers. She touched one. It opened. Inside was a seed. She smiled. And from somewhere nearby, a voice called softly: "I'm just about finished, sweetie." She turned toward the sound. "Just another minute, I promise." The child stood. She brushed the petals from her hands. And she went to find her father. The end is a very small place. There is room enough for a beginning.
