that was my thought if similarly formed systems behaved similarly in their rotation that was my thought if similarly formed systems behaved similarly in their rotationWhen you look at “stellar nurseries” such as the famous Hubble Eagle Nebula shot, there seems to be quite a bit of turbulence, I guess you could call it, with swirls of various orientations. I don’t think the galactic rotation is imparted to these swirls in the same way the presumed proto-solar system imparted its rotation to the planets. This would be because the galactic scale is so huge, and the stars are imbedded in a thickness much greater than the size of a planetary system.
Just my own musings!
