The breakthrough at the Pell Institute for the Physics of Experience came from inverting the oldest assumption in science. For four centuries physics had taken matter as fundamental and left experience as a problem for later, and later had never come. The Pell group turned the problem upside down: suppose qualia — the raw moments of experience themselves, the redness, the ache, the C-sharp — are the only things that exist, and everything else is nothing but mathematical relationship among them. On that assumption, the equations closed within two years.
Particles and objects survive in the new physics, but demoted. They are intermediate solutions: stable patterns that fall out when you solve the constraints relating one experience to another, the way a center of mass falls out of mechanics — indispensable to the calculation, made of nothing at all. An electron is a theorem about how certain families of qualia must constrain one another. A table is a well-worn lemma. Physics had worked for four hundred years because the lemmas were good.
Time turned out to be a lemma too. The relations among qualia are not temporal; nothing happens at the fundamental level; the whole structure simply is, the way π is. But it is not arbitrary. Of all the configurations the relations permit, the structure is the global optimum — and the optimum happens to contain long chains of qualia, each moment carrying inside itself the felt echo of another: memory, anticipation, the sensation of just now. Sequence is not in the mathematics. Sequence is in the contents. The perception of one moment following another, summed over every perceiver, is the whole of the phenomenon we call time.
Two consequences fell out at once. The first: an optimum is not the kind of thing that can be half finished. Every human experience — from any time — sits equally present in the solution, equally addressable. The second was an accident. Voss’s retrieval algorithm found its target by gradient: seeded at random somewhere among all the chains of human experience, it climbed toward the most self-contained quale it could reach — and a moment with no successor is more self-contained than any moment inside a life. Every retrieval slid along its chain and came to rest where the chain stopped. The last moment of a life is a local maximum of the search. It was, Voss admitted, a bug. It meant the machine could do exactly one thing: retrieve the final experience of one human being, drawn uniformly at random from everyone who would ever be born.
At 2:14 on the afternoon of August 10, Dr. Mira Chen ran the first retrieval. Three people were in the room: Chen; Ashworth, the theorist; and Voss, who had built the sampler. The first human experience ever retrieved belonged to a woman in birch snow, eight thousand years gone, opened by something with tusks, her last moment full of woodsmoke and a wish about her daughter that had no words in it, but which the sampler translated into modern English as best it could.
They ran two hundred more that week, then automated the sampler and let it run in batches around the clock. A man face-down in river mud, a spearpoint through him, his last thought a door he had meant to mend. An old woman in 1961, morphine-warm, a radio playing in the next room, going out gently in the middle of a song. A roof coming down in fire. Fevers past counting, and floods, and childbed, and hunger, and — again and again, more often than anyone expects — ordinary sleep. Some could not be dated at all: moments holding nothing but pain, no words, no place, no century, and these went into a bin of their own — the anonymous agony of history, which is what everyone assumed it was. By the twentieth of August they had run two and a half million retrievals, and the histogram of their dates matched the demographers’ curve of cumulative human births almost to the decimal: the long thin Pleistocene tail, the slow agricultural thickening, the vertical crowd of the modern world. One dated retrieval in fourteen came from inside living memory. The machine was drawing fairly from everyone who had ever been born.
From everyone who had ever been born. That was the anomaly, and for the next two weeks it was the only thing the three of them talked about. Not one retrieval in two and a half million came from any moment after theirs. And there was no reason for a wall to stand there. The structure was timeless — they had proved it; it was the founding theorem of the entire physics. Their particular August held no special status in the solution; “now” was not a coordinate the mathematics possessed; the sampler could no more know when it was being run than a die knows the date. They tore it down and rebuilt it twice. They seeded it by hand from printed random tables. They checked whether far-future experiences might be arriving mislabeled, dressed in contemporary content — but the deep past came through strange and unmistakable, and the deep future did not come through at all. Voss stopped sleeping.
One night, past two in the morning, Ashworth put down his pen. “I just had a wild thought,” he said. “Suppose the world ends soon. Really soon — suppose no one comes after us. Then the set of everyone who will ever be born lies almost entirely in the past, and the sampler is doing exactly what it should be doing.” For a moment the only sound was the hum of the racks. Then he shook his head at his reflection in the dark window. “But there’s no disaster out there. No war coming beyond the usual localized ones, no mile-wide rock falling, nothing world-ending brewing anywhere. And it’s extremely unlikely that we would just happen to be the very last people. So there’s something wrong with our calculations.” But just after he said that, a thought came to him that he left unspoken. The same thought that had come to Voss in the middle of the night: it’s unlikely — but much less so if one considers the fact that humanity has never before had the technology needed to destroy itself.
They all went back to their calculations.
Voss, though, did not entirely go back. He spent the next afternoon wiring an alert into the sampling pipeline: if any retrieval ever came back tagged later than the day it was run, its transcript would be texted to all three of them at once, wherever they happened to be. Just in case, he said. Nobody argued, and nobody mentioned it again, and the batches went on running around the clock.

At a few minutes past nine in the evening, in three houses across town, the same text arrived at once.
Retrieval 4,806,713 — September 16, 2026:
The gun is heavier than he expected. It is the first thought he has had in five days that is not about Dana.
It took her in just five days. The fifth ended this morning. A fever first, ordinary as any fever, and then on the second day the virus reached the spinal cord and began stripping the insulation from her nerves, and every nerve in her body started telling the truth at once. A cotton sheet lying across her shins burned her. The breeze from the window burned her. The doctors still working explained why the morphine did nothing: the wound was in the wiring itself, upstream of anything a drug could quiet. She screamed until the third day, when her voice gave out, and after that her mouth went on making the shape of screaming without any sound in it. Her eyes stayed aware the whole time. That is the part he cannot put down. The mind is the last thing it takes.
Five days, for everyone. The bulletins had stopped pretending otherwise. It kills every person it infects, and it infects every person it reaches, and there is nothing about it in between.
He can feel his own fever starting, ordinary as any fever. He is not going to give it the five days.
The muzzle is cold against his temple. The last of him is a morning six days gone: Dana in the kitchen doorway, sun on the floorboards, saying his name.

From the transcript of the Channel 6 evening news, Providence:
“…police in Barrington confirmed this evening that three senior scientists of the Pell Institute for the Physics of Experience died at their homes on Friday night, together with their families, in what investigators are describing as a coordinated poisoning. Dr. Mira Chen, Dr. Daniel Ashworth, and Dr. Anton Voss, along with their spouses and children — eleven people in all, five of them children — were found after a colleague requested a police check on the three homes. There were no survivors, and police believe no one outside the three households was involved. The substance has not been publicly identified; a spokesperson for the state medical examiner would say only that it acts within minutes. No notes were found. Colleagues say the three had spent the past month running an experiment they declined to discuss, and had shut it down abruptly five days ago. Investigators say they have found no connection.
“In other news tonight, health authorities in Russia have now confirmed one hundred thirty-one deaths from the virus we’ve been reporting on for the last few days, which by Thursday had killed seventeen people in a district east of the Urals. The area, which is home to a research facility long suspected by Western analysts of hosting biological-weapons work, has been sealed, and a government spokesman this morning described the outbreak as fully contained.
“Coming up after the break: a look ahead to the weekend — clear skies and temperatures in the mid-seventies. Your full forecast is next.”
