The 30 pages that link to Gravitational collapse, each with the reason it gives.
Galaxy clusterRelated: It drives the formation of dense regions that become galaxy clusters.
PlanetesimalRelated: Dense particle clumps can collapse into planetesimals.
ProtostarRelated: It begins the dense, central condensation that develops into a protostar.
Solar System formationRelated: Collapse initiated the formation of the Sun and its surrounding disk.
Schwarzschild radiusRelated: Collapse can concentrate mass inside its Schwarzschild radius.
Substellar objectRelated: It can form substellar bodies directly, without a protoplanetary disk.
Interstellar cloudRelated: Collapse can turn dense cloud regions into protostars.
