What is collisional cascading?

Collisional cascading is a process that occurs in astrophysical contexts, particularly in the formation and evolution of planetary rings and debris disks. It involves the fragmentation of larger objects into smaller particles due to collisions, leading to a chain reaction where smaller fragments collide and break apart further. This process can significantly influence the size distribution of debris and the dynamics of the system over time. Ultimately, collisional cascading plays a crucial role in shaping the structure and composition of planetary systems.
