Editing Dynamical friction (section)

===Star clusters===
The effect of dynamical friction explains why the most massive stars of SCs tend to be found near the center of star cluster. This concentration of more massive stars in the cluster's cores tend to favor collisions between stars, which may trigger the runaway collision mechanism to form intermediate mass black holes.{{cn|date=June 2024}} [[Globular cluster]]s orbiting through the stellar field of a galaxy experience dynamic friction. This drag force causes the cluster to lose energy and spiral in toward the galactic center.<ref>{{cite journal
