Is Special Relativity a Decidable Theory?
Helmut Hansen
In this paper a new principle is proposed: The Principle of Dual Constancy of Light. It implies the assumption that not only light itself, but also its speed c is of dual nature. That means, the speed of light c is given in a wave-like and in a particle-like form. Using this new principle the empirical undecidability of the Second Postulate of Special Relativity could be revealed.
