Quote: "but the stars that form further out in the flow experience less deceleration and can even fly off out of the galaxy altogether."
CONCLUSION : Support for GABHs ( dual Galaxy Anchor Black Hole system perpendicular to the galaxy !!.
The Q-FFF Rigid String Theory says: (1) There is only one CONSTRUCTIVE Topological and Resilient TRANSFORMING STRING (Axion/vacuum Dark Energy building block ), forming direct after the Black Hole Splitting Big Bang. so called Travelling TADPOLE Black Hole based Filaments, expanding the Cosmic Lyman Alpha Structure. (2) A Raspberry Entangled 12x Mirror Copy Multiverse is Postulated as base for uncertainty (ER=EPR) and Libet's FREE VETO WILL . SO We live inside an exploded BH
QUANTUM FFF topological STRING THEORY and the Fermion Propeller.http://vixra.org/author/leo_vuykhttps://www.flickr.com/photos_user.gne?path=&nsid=93308747%40N05&page=&details=1If the big bang was the splitting of a huge Axion/ Higgs particle Dark Matter Black Hole (ELISIUM DM- BH) nucleus into smaller DM-BH nuclei, then no standard Fermion/ Baryon inflation has happened only the DM-BH based Lyman alpha forest equipped with local Herbig Haro star/galaxy creating systems.
All black holes of all sizes (down to ball lightning) seem to be equipped with a Fermion repelling- and plasma producing horizon, which has also a charge splitting effect into a negative (outside) and positive ( inside) zone ( see oriental basin of the moon) .Conclusion, all Bhs are: "Negative Charged Electric Dark Matter Black Holes" with a rigid open string sector with intrinsic 3x hinging curvature.
