The
main object of the elementary
body theory is the elementary body
a pulsating hollow sphere. At
maximum expansion the hollow spherical shellmass is at rest.
The
equations of motion  based on a sine function  describe
the complete transformation of this shellmass into motion
energy without rest mass (photon).
Overall the deduced dual system created by the
elementary body consists on average of no
energy, no mass and no space.
Negative
energy values e.g. of the Dirac equation are
natural results of the elementary body dynamics.
A
consideration of the elementary body
provides an accurate theoretical value for the proton radius.
Elementary body theory based the proton radius is the
Compton
wavelength λ_{C}
of the proton divided by π / 2. This
result is in excellent accordance with the measured value of
the proton radius (investigation muonic hydrogen, July 2010
and 2012/2013 at the Paul Scherrer Institute in Switzerland.
