The idea that space is a material continuum with standard mechanical properties such as elasticity and viscosity is applied to the propagation of shear waves (electromagnetic waves). The viscosity is shown to introduce dispersive dissipation in the governing system which affects differently the propagation of waves of different frequencies. This results in redshifting of a spectral line without the need to assume Doppler dilation of each of the frequencies constituting the packet. It is shown that the wider spectral lines experience larger redshift than the thinner one which is in very good agreement with the observation of the high-redshift objects, such as Quasi-Stellar Objects (QSOs or Quasars). The data for the spectral lines of the QSO 3C273 is analyzed in detail from the point of view of the proposed model. The conclusion is the the mere dissipation is not enough for good quantitative explanation of the redshift, and that dispersive effects should also be taken into account.
