  Consequences of the consistent exact solution of Einstein-Cartan equation on
the time dependence of Hubble parameter are discussed. The torsion leads to a
space and time dependent expansion parameter which results into nontrivial
windows of Hubble parameter between diverging behaviour. Only one window shows
a period of decreasing followed by increasing time dependence. Provided a known
cosmological constant and the present values of Hubble and deceleration
parameter this changing time can be given in the past as well as the ending
time of the windows or universe. The comparison with the present experimental
data allows to determine all parameters of the model. Large-scale spatial
periodic structures appear. From the metric with torsion outside matter it is
seen that torsion can feign dark matter.
