Loss of charge in a Lienard Wiechert Potential implies a hidden   contraction
  In the paper it is demonstrated that a point-like dust in a Lienard-Wiechert potential under the constraint of axial gauging must change its velocity 'beyond' a mere change in direction when a fraction of charge is lost at a point in space-time. The existence of a postulated hidden entity that introduces a Lorentz contraction avoids a concealed contradiction in repeated experimentation with charge loss in point-like dust.
