 -ellipsoid shape when at rest. When in uniform translation, then according to the electron undergoes the known  contraction. Now, is an uniform translation into every direction in a force-free manner for this electron possible, or not?

If it is not possible, then for the sake of the relativity principle, one has to exclude the existence of such electrons in favor of a new hypothesis; otherwise we indeed would possess by them an instrument to demonstrate absolute motion.

If it should be possible, then we would have to show as to how they can be derived from the ian system, without the use of totally new axioms.
