One thought that occurs to me is that large-scale structures like sheets and black holes with parallel axes of rotation could be the result large directional explosions soon after the big bang rather than the result of a large force acting now.

Where would these directional explosions come from?

  While I'd note one doesn't necessarily need an set explanation for such directional explosions to formulate decent theory (look at dark matter, etc), I think electromagnetic forces often produce highly directional effects.

    There are large-scale anistropies in the universe, and the origin of symmetry-breaking at cosmological scales is an unsolved problem. Either a force or type of matter is unaccounted for / incorrectly modeled, or the big bang was not symmetrical. https://en.wikipedia.org/wiki/Axis_of_evil_(cosmology) https://en.wikipedia.org/wiki/Axis_of_evil_(cosmology)

I dont even think you need the explosion. You can imagine two gas sheets sliding along eachother. All of the vortices formed between them will spin in the same plane. You can imagine similar trends for interacting spheres and other geometries.

That was my first thought too, but my knowledge on the topic is tiny and I was hoping the article would explain why that wasn't possible.

There would have to be objects or structures already there to explode. That just doesn't fit with current models. This may well point to there being more structure or asymmetry in the very early universe, but things that can explode being present there is a pretty extreme version of that.

I think we should be careful when explaining things in universe by tying it all the way back to big bang. I was discussing about this in another comment below. Then I wrote a thought piece about it here; https://medium.com/@suphievrakzade/abstraction-layers-for-the-universe-97bb524269eb https://medium.com/@suphievrakzade/abstraction-layers-for-th...
