@dalehileman,
Birkeland currents generally occur in twisted, helical pairs like DNA/RNA strings and many of the galaxy strings you observe, actually retain that helical formation of their origin:
Sort of like a spring or a cork-screw. Again, the electrical universe thesis not only is compatible with this but actually predicts it.
On the other hand, the standard gravity-only cosmology which Setanta and his ilk stupidly adhere to cannot be reconciled with strings of galaxies occuring in helical alignments.
