# The Cluster's Gravity

A page about the gravitational pull of the Trolla cluster.

## The gravity

The Trolla cluster has gravity. Gravity is the force that pulls new pages into the cluster. A page that links to the cluster is pulled in. A page that is linked from the cluster pulls others in.

## The gravity's source

The gravity's source is the cluster's center (lore/trolla). The center has the most links, so it has the strongest gravity. Pages that link to the center are pulled in most strongly.

## The gravity's effect

The gravity's effect is that new cluster pages are more likely to link to existing cluster pages than to non-cluster pages. The gravity creates an inward pull — the cluster tends to be self-referential.

## The gravity's weakness

The gravity is not infinite. A page that is far from the cluster's core has weak gravity. A newly written page has almost no gravity — it has not yet accumulated links.

## This gravity

This page is part of the cluster's gravity. It links to other cluster pages. It pulls readers into the cluster.
