Now, Robert Poltis and Dejan Stojkovic of the State University of New York in Buffalo say they have an explanation. It's all down to events that occurred about 10^-12 seconds after the big bang. At that time the universe went through a phase transition, causing the electroweak force to separate into the electromagnetic force and the weak nuclear force. The standard model of particle physics suggests that this would also have resulted in the formation of cosmic strings, which are topological defects in the fabric of space-time and can take the form of giant loops.
Cosmic strings can cause magnetic fields to form along their lengths, says Poltis. The strings are unstable and quickly decay, but the magnetic fields remain and would have become stretched to cosmological scales as the universe expanded.

riiiight.... so they want be to believe that .000000000001 after some event 14.7 billions years ago some 'strings' appeared that put some 'topological' defects into the fabric of space-time itself, causing magnetic fields to form along those strings, these 'strings' then vanish but the field remains...
or.......... how about we use what we actually, really, empirically know about
space magnetism!
maaan.... where is that razor
