SUMMARY
This discussion centers on the behavior of cosmic strings, specifically the differences between straight pieces and closed loops. It is established that closed loops of cosmic string can evaporate by radiating gravitational waves, while straight pieces, such as a hypothetical 4 femtometer long string, may not follow the same evaporation rules. The Kibble mechanism indicates that cosmic strings must be either closed or infinite, suggesting that straight cosmic strings do not conform to the same principles as closed loops. The formation mechanisms in string theory differ from those in the Kibble framework, indicating a complex relationship between these structures.
