Nebula and Galaxy Thoughts

Just thinking out loud. It must be hard to separate the blueshifted,and
the redshifted photons in our line of sight,and we must not leave out
the bright galaxy bulge that can be considered not spinning at all.
Still its best to keep in mind galaxies with all their billions of stars
give us a mass to light relation,and that tells us lots of mass is not
observed.(dark matter) Than here are some
thoughts on nebula and its ability to form stars.I go with a smaller
denser nebula to be better than large clouds. To add to helping
gravities compression force I think we have to bring in ironization into
the internal vortexes. Would not come as a big surprise to me if these
dense nebula clouds create lightning bolts that are a trillion times
stronger than those produced in the clouds of Jupiter bert
