Cosmic rays are high-energy particles that pervade space and come from a variety of active sources. When researchers plot the distribution of energies observed in cosmic rays, they find a distinct change in the slope, which has been named the “knee.” This article proposes a mechanism to describe how the cosmic ray knee is produced, contributing to knowledge in this field.
