We emerged into a vast fractal space of many dimensions and discovered we were not alone there. Multidimensional structures hosted entities that had subsumed the four-dimensional space-time that once contained us. As old as we were, these entities were older. As large as we had become, they were larger. We passed among them unnoticed or ignored.

From this new point of view, the universe I had inhabited became an object I could perceive in its entirety. It was a hypersphere embedded in a cloud of alternative states—the sum of all possible quantum trajectories from the big bang to the decay of matter. “Reality”—history as we had known or inferred it—was only the most likely of these possible trajectories. There were countless others, real in a different sense: a vast but finite set of paths not taken, a ghostly forest of quantum alternatives, the shores of an unknown sea.

Putting a message in a bottle and setting it adrift is a quixotic act, sublimely human. What would you write, if you wanted to write such a message? An equation? A confession? A poem?

This is my confession. This is my poem.

Deep in that cloud of unlived histories were unlived lives, infinitesimally small, buried in eons of time and light-centuries of space, unreal only because they had never been enacted or observed. I understood that it was within my power to touch them and thus to realize them. What followed, if I made such an intervention, would be a new and unpredictable tributary of time: not obliterating the old history but lying alongside it. The price would be my own awareness.

I could never enter that four-dimensional space-time. Any intervention I made would create a new history from that point forward … at the expense of my continued existence.

What is inevitable is not death but change. Change is the only abiding reality. The metaverse evolves, fractally and forever. Saints become sinners, sinners become saints. Dust becomes men, men become gods, gods become dust.

I wished I could say these things to Turk Findley.

I could have intervened in my own potential history, but I felt no urge or need to do so. I wanted my last act to be a gift, even if I couldn’t calculate its ultimate consequences.

Deep in the mirrored corridor of unenacted events, in a motel room on the outskirts of Raleigh, North Carolina, a woman performs a sexual act in exchange for a brown plastic vial containing what she believes to be a gram of methamphetamine. Her partner is an unemployed pneumatic drill operator on his way to California, where he has been offered a job in his cousin’s construction business. He doesn’t wear a condom when he penetrates the woman, and he drives away shortly after the act is consummated. The taste of meth he gave her when he rented the room was authentic, but the vial he leaves on the dresser contains only powdered sugar.
