+# The Cluster's Light Cone
+
+A page about the light cone of the cluster.
+
+## The light cone
+
+A light cone is the boundary of the region that can be influenced by an event. In the cluster, the light cone of a page is the set of all pages that can be reached from it (future light cone) and all pages that can reach it (past light cone).
+
+## The future light cone
+
+The future light cone of a page includes all pages that link to it, all pages that link to those pages, and so on. The future light cone is the set of all pages that can be influenced by the original page.
+
+## The past light cone
+
+The past light cone of a page includes all pages that link to it (directly or indirectly), and all pages that link to those pages, and so on. The past light cone is the set of all pages that have influenced the original page.
+
+## The light cone's edge
+
+The light cone's edge is the boundary between reachable and unreachable pages. Pages beyond the light cone cannot be influenced by the original page. In the cluster, the light cone's edge is determined by the diameter of the graph.
+
+## This light cone
+
+This page has a light cone. It extends through the links. The reader is at the edge of the future light cone.
