Cosmological Redshift and Light Velocity in Vacuum
Keywords: Doppler effect, cosmological redshift, light velocity, vacuum
An alternative to the explanation of the redshift by Doppler effect is proposed. Since it has been shown in particle generation by electrtomagnetic interaction and in other examples that a vacuum is not a void, but has a material character, it is reasonable to assume that light waves meet a certain resistance when propagating through vacuum. When a corresponding term is introduced in the wave equation, the solution results in a change of velocity and wavelength, but not in frequency. At the same time there is extinction over very long distances, and this provides a natural explanation of Albers' paradox.
