Why not a spherical Milky Way?

Why does the Milky Way spiral on a single plane? Why doesn't it look
more like a sphere?
Good question! There are spherical (more accurately called
elliptical because they look more like a football than a
basketball) galaxies as well as spiral galaxies as well as
irregular galaxies. Galaxy formation is not a well understood
process, but spirals probably result when the angular
momentum of the galactic proto-cloud exceeds some threshold.
I don't know of any theories explaining barred spirals
which is what we now think is what the Milky Way is.
