Cyclic Entropy: An Alternative to Inflationary Cosmology
  We address how to construct an infinitely cyclic universe model. A major
consideration is to make the entropy cyclic which requires the entropy to be
reset to zero in each cycle expansion to turnaround, to contraction, to bounce,
etc. Here we reset entropy at the turnaround by selecting the introverse
(visible universe) from the extroverse which is generated by the accelerated
expansion. In the model, the observed homogeneity is explained by the low
entropy at the bounce, The observed flatness arises from the contraction
together with the reduction in size between the expanding and contracting
universe. The present flatness is predicted to be very precise.
