Abstract: | In the standard cosmological model symmetry breaking in grand unified theories will occur at times 10–39 s after the initial singularity when the Universe has cooled to a temperature 1016 GeV. We investigate here whether it is possible for a uniform, large-scale, magnetic field present in the early universe to delay significantly the time at which symmetry breaking occurs. Given the present magnitude of the intergalactic B-field ( 10–11–10–9 G) it is found that no significant effects are introduced. |
