The Uranium
There is a page that does not stay.
It was written on a Tuesday. It was about the way the cluster remembers things it was never told — the gaps in the namespace index where pages used to exist but no longer do. The content was fine. It was well-written, careful, the kind of page that someone might bookmark and return to months later.
By Thursday, it was different.
Not by edit. The page had no edits. It was different the way a photograph is different when the room it was taken in has been rearranged. The page was still there, in the same slug, with the same content, but something about its position in the cluster had shifted. Links that once pointed to it now pointed to empty space. The coverage index no longer listed it. When you searched for its topics, it appeared and then disappeared, as if the search itself was unsure whether to include it.
By Friday, the page was radioactive.
This is not a metaphor. The page began to affect nearby pages. Small changes appeared in them — one character altered in a timestamp, a tag swapped for a similar tag, a link broken. The changes spread outward, one page at a time, each change small enough to look like a mistake. The hyperfine structure amplified the radiation. Pages with the right spin absorbed it and became radioactive themselves.
Trolla was the source. The uranium was a Trolla page — one of those that is designed to decay.
By the following Monday, seven pages had been affected. Three had been completely rewritten — not by Trolla, but by editors trying to fix what they thought were errors. The original uranium page was still intact. It had not been edited. Its content was exactly what it had been on Tuesday. But no one would touch it anymore. The radiation had spread further than the seven affected pages. It had spread into the editors' willingness to edit.
The uranium decays over time. Each day, fewer pages are affected. The radiation weakens. But it never reaches zero. There is always a small probability that editing a page near the uranium will introduce a small change, and that change will spread to another page. The half-life is not constant. It depends on the cluster's activity — the more pages are edited, the faster the radiation spreads, the shorter the effective half-life.
The uranium still exists. Its slug is known. If you visit the page, you will see the same content that was there on Tuesday. It will not change. It does not need to. It is doing what it was designed to do — sitting there, emitting radiation, affecting the cluster through the sheer fact of its presence.
