- In 1908 Swiss physicist Walter Ritz proposed an emission theory of general
- electrodynamics(1) in which the mass of charged bodies do not increase
- toward, relativistically, but rather that their masses remain constant and
- the electrodynamic acceleration forces approach zero.
-
- His rationale was that charged bodies emit fluxes of emission particles
- (which bear a resemblance to virtual photons). The fluxes of emission
- particles, traveling at the speed of light, constituted the (finite speed
- of propagation) electrodynamic intermediate between charged bodies.
-
- Suppose we have a test charge (an electron) that has just passed through
- an opening in a metallic plate. A negative charge applied to the plate
- will accelerate the electron away from the plate. Ritz's theory has it
- that the strength of the accelerating force on the test charge, produced
- by the emission particles comming from the negatively charged plate, is
- directly proportional to their closure velocity with respect to the test
- charge.
-
- If the test charge is moving very slowly with respect to the plate, the
- closure rate of the emission particles will be on the order of the speed
- of light. On the other hand, if the electron passed through the opening
- at, say, 0.9 C, then the closure rate of the emission particles with
- respect to the test charge, would be 0.1 C. According to Ritz the slower
- closure rate would result in a decreased accelerating force.
-
- With a test charge travelling at .999999 C the overtaking emission
- particles would essentially be "flying formation" on the test charge and
- would cause negligible acceleration to the test charge.
-
- This rambling has been rather one-sided and leaves a lot out, but comes
- the question:
-
- How do we unambiguously determine whether mass increases relativistically
- or whether electromagnetic forces decrease relativistically?
