Evolution of Cosmic String Networks ’ d , 9 y g /

We summarize our new results on cosmic strings presented in [l]. These results include: (1) The application of non-equilibrium statistical mechanics to cosmic string evolution. (2) A simple “one scale” model for the long strings which has a great deal of predictive power. (3) Results from large scale numerical simulations. (4) A discussion of the observational consequences of our results. An upper bound on Gp of approximately lo-’ emerges from the millisecond pulsar gravity wave bound. We discuss how numerical uncertainties affect this. Any changes which weaken the bound would probably also give the long strings the dominant role in producing observational consequences.
