It's structures like this that constantly poke holes in the BB. The BB doesn't predict these. However this particular structure is exactly what I would expect from plasma theory ala Hannes Alfven.
The problem with the BB is that every time something is discovered that the BB couldn't predict, it is "tweaked" to include the new structure. It is more of a Crazy Quilt, now than a simple theory.
Is there reason to expect that the universe should conform to any simple geometric structure?
