Phys. Rev. Lett. 89, 271301 (2002) [4 pages]Topological Defects in Contracting UniversesSee Also: Publisher's Note Received 8 August 2002; published 16 December 2002; publisher error corrected 20 December 2002 We study the behavior and consequences of cosmic string networks in contracting universes. They approximately behave during the collapse phase as radiation fluids. Scaling solutions describing this are derived and tested against high-resolution numerical simulations. A string network in a contracting universe, together with the gravitational radiation it generates, can affect the dynamics of the universe both locally and globally and be an important source of radiation, entropy, and inhomogeneity. We discuss possible implications for bouncing and cyclic models. © 2002 The American Physical Society URL:
