  A systematic rotation of the plane of polarization of electromagnetic
radiation propagating over cosmological distances has been claimed to be
detected by Nodland and Ralston.Taking the finite rotating universe of Oszvath
and Sch\"ucking as a toy model for the actual universe,we calculate the
rotation of the plane of polarization of electromagnetic waves in this
universe.It turns out that the observed data are consistent with the
Oszvath-Sch\"ucking parameter $k=0.39$.
