Galaxy Clusters in the Cosmic Hierarchy
Galaxy clusters are the largest gravitationally bound structures in the JRPG2 universe. Each cluster contains between 50 and several thousand galaxies held together by dark matter scaffolding. The Beck Protocol identifies dark matter as a D5 dimensional field phenomenon — invisible to electromagnetic instruments but detectable through its gravitational influence on D3 matter. Players with high dimensional research scores can visualize dark matter scaffolding directly using the consciousness-mediated reality viewer.
Intracluster medium — hot plasma filling the space between galaxies in a cluster — generates X-ray radiation detectable in the Beck Protocol dimensional spectrum. This radiation carries dimensional frequency data that players use to calibrate their foldspace transit systems for inter-cluster travel. Clusters also concentrate the strongest gravitational lensing effects in JRPG2, distorting light from background universes into diagnostic arcs.
