#fundamental_interaction__interaction  (physics) the transfer of energy between elementary particles or between an elementary particle and a field or between fields; mediated by gauge bosons
  supertype:  physical_phenomenon  a natural phenomenon involving the physics of matter and energy
  subtype:  electromagnetic_interaction__electromagneticinteraction  an interaction between charged elementary particles that is intermediate in strength between the strong and weak interactions; mediated by photons
  subtype:  gravitational_interaction__gravitationalinteraction  a weak interaction between particles that results from their mass; mediated by gravitons
  subtype:  strong_interaction__strong_force__color_force__colorforce  (physics) the interaction that binds protons and neutrons together in the nuclei of atoms; mediated by gluons
  subtype:  weak_interaction__weak_force  (physics) an interaction between elementary particles involving neutrinos or antineutrinos that is responsible for certain kinds of radioactive decay; mediated by intermediate vector bosons
