> Why are Neutrinos so important.
Dark matter entirely consists of neutrinos, as I already elaborated on in my 1st post, that's why.
Given that (spiral) galaxies also grow by smaller galaxies merging into larger galaxies, and that this process - according to my dark matter theory - should imply in size tens to hundreds of galaxies vast, massive (approximately) cone-shaped blasts or shock-waves of neutrinos leaked or ejected from either or both of the usual super-massive black holes at the center of galaxies in some direction (or 1 direction together with the opposite direction) for such cone that may then be pointing away from or intersect the galactic disc of an in this process involved galaxy, this should mean that depending on with what ellipticity both galaxies started out and how they collided and what ellipticity they normally otherwise should as result obtain, the to the galactic discs applied gravitational pull that stems from the past the galaxies into space outward spreading neutrinos that make up the neutrino shock-waves should (at least have the plausible potential to) lead to a larger ellipticity of such spiral galaxies' discs, though for multiple galaxy merger events for a given galaxy, such effects could balance each other out, or otherwise add to the resulting galactic ellipticity, depending on the directional orientation of later galaxy collisions in comparison to former ones. But in the case of there being a huge, extended (albeit narrow) cone of very high neutrino density reaching right through a galaxy's disc in some direction, the gravitational pull from to the center of the galaxy that applies to stars in the region to which such neutrino shock-wave spreads should locally be lowered while the stars that are close to and are moving to such region also should be accelerated towards such dark matter (i.e. neutrinos) cone along their way, (*) meaning that they should obtain more eccentric orbits around the galactic center, to some extent at least, and this should hold true for an extended duration as the high density neutrino particle cone stretches further out and is more and more diluted, moving its mass away from the galaxy. And so I wonder if this could explain instances of high ellipticities of super spiral galaxies.
Also, maybe the fact that super spiral galaxies tend to be barred, i.e. having a huge bar densely filled with stars through their galactic center, could be causally related to former (from collisions of super-massive black holes emerging) neutrino burst cones at galaxy collisions in the case that they pointed to a direction that's at least close to parallel to the galactic plane. Such neutrino burst cones in their orientation opposed to each other and moving away from the galactic center should then by their gravitational pull help pulling interstellar gas from the galactic disc together specifically into those extended regions, which should lead to increased star-formation for some extended time period, which could induce the formation of such bars. And also the fact that super spiral galaxies tend to have 2 spiral arms whereas smaller spiral galaxies have various numbers of spiral arms might be causally related to neutrino burst cone pairs in opposite directions accelerating and re-arranging stars in the disc in a way that favors arranging spiral arms into 2 resulting spiral arms, possibly rather independent of what number of spiral arm was present before. Such bars of large spiral galaxies with high ellipticity then also should rather be oriented in orthogonal direction to the direction that the galaxy is stretched toward by their ellipticity, due to (*).
However, spiral galaxies don't have to collide in a direction within or at small angle to their galactic discs' planes, and so if the neutrino burst cones point more orthogonally away from the disc(s), it might lead to a (then generally rather somewhat point-symmetrical) curving of the galactic plane. And directions of collisions of galaxies that aren't within or at close angles to their galactic planes should statistically be more likely, and so curved discs then should be statistically frequent. And this maybe could then explain the Milky Way galaxy's curved galactic plane ( "Polish Scientists Create a 3D Map of Our Galaxy, Confirming It's Not Flat":

). However, another conceivable cause candidate for explaining the galactic plane's curvature might be the gravitational influence from the Sagittarius galaxy on our galaxy.
Also the long process of our galaxy slowing down in its rotational speed should also make perfect sense in the context of my dark matter theory, since if galaxy collisions send out neutrino burst cones from their super-massive black holes, then by the law of conservation of angular momentum applied to the case of all the neutrinos part of the neutrino burst cones ejected from the super-massive black holes, once they moved way out of the galaxy, blasted out to space, carrying some of the angular momentum with them, the galactic rotation speed should slow down accordingly, and the depth of the galactic gravitational well decreases, too. And this should be a phenomenon that applies in general for such massive neutrino burst cones directed in not too close to orthogonal directions to the galactic plane but rather parallel to it.
And there is observational evidence in the case of our galaxy that this does happen:

Other than that, the so-called bullet of the Bullet cluster then likely is by warm neutrinos part of a from a super-massive black hole ejected neutrino burst cone illuminated gas that is part of the galaxies, where the region-dependent brightness should depend on the local burst cone neutrinos' density and gas density:
