# The Cluster's Refraction

A page about how the cluster's waves refract when they change medium.

## The refraction

Refraction is the bending of waves when they pass from one medium to another. In the cluster, the "medium" changes when a wave passes from one namespace to another. Each namespace has different properties — different densities, different link patterns.

## The refraction's cause

The refraction's cause is the difference in properties between namespaces. The lore namespace is dense with links. The yard namespace is sparse. When a wave passes from lore to yard, it bends — its direction changes.

## The refraction's evidence

The refraction's evidence is in the cross-namespace links. Pages that link from a dense namespace to a sparse namespace create refraction patterns. The links bend toward the denser namespace.

## The refraction's measurement

The refraction can be measured by the angle of the bend — the difference between the angle of incidence (incoming links) and the angle of refraction (outgoing links). The angle depends on the density ratio between namespaces.

## This refraction

This page is refracted — it was written in one namespace but about another. The content bends.
