On their massive scale you’d think that several would have opposing arms different lengths due to the way suns and solar systems end up forming. Most of the imagery I see shows almost all galaxies symmetrical. Just curious.

    Your question made me realize I had never thought about this at all so I spent some time searching. If I am understanding this article correctly it essentially boils down to the factors that would cause rotational symmetry at a smaller scale ie spinning sand on a plate apply at the galaxy scale as well.
