Over-merging on galactic scales is a necessary requirement, other-wise previous generations of the hierarchy would preclude the formation of disks. Observations suggest that overmerging has been nearly complete on galactic scales.

This process begins with the collision of dust due to Brownian motion producing larger aggregates held together by van der Waals forces. The aggregates settle toward the mid-plane of the disk and collide due to gas turbulence forming pebbles and larger objects. Further collisions and merger… lvg group srl
