Massively Parallel Simulations of Cosmic Strings
Abstract
A cosmic string is an ultra-thin tube of exotic matter which may have been left over from a very early hot, dense phase of the Universe’s history1, 2. Certain Grand Unified Theories, which are theories purporting to describe all the elementary particles and their interactions on an even footing, predict the existence of strings. If the temperature was ever high enough, the strings would have inevitably formed in a tangled network, and would still be present today, albeit greatly diluted, but still with possible observational effects. Thus the study of their properties and dynamics helps us get information about the earliest phases of the Universe’s history.
