Force                  particle        relative strength range (meters)

Electromagnetic  photon                1/137                       infinite

Gravitational          graviton             6 X 10-39                ifinite

Weak nuclear          weakon         $10^{-5}$          $10^{-17}$

Strong nuclear  gluon                    1                      $10^{-15}$
