It takes time, but we'll progress from this dead point we are in, the solution isn't quantum gravity, it's very likely classical. This philosophy of "nature is random" because we don't have a theory that let those parameters emerge rather than being spoon fed is detrimental.

Making stuff up isn't a way to solve problems.

Seems like some misunderstanding is going on.
Let's take a different tact....
Sagittarius A does not have enough mass to anchor all the matter in our galaxy in place. If not for Dark Matter the galaxy should be a lot smaller in size. If the effects of dark matter could be suddenly turned off, the galaxy would be flinging stars away from it at crazy velocities.

Please do note that all things have dark matter in them including us, yes we are expanding with the universe FTW!

Dark energy causes space to expand, not dark matter.

Dark energy and matter are part of everything including us, we are expanding with the universe.

As I explained to intrptr on the first page, any system with most of the mass at the center should have a rotational curve which drops off proportional to the distance. Your theory explains absolutely nothing about why that flat rotational curve exists. It doesn't matter if it's a black hole or black body at the center of the galaxy, the same rules apply.

we do see spiral arms.... the outer rims seem slower.... further from centre is slower.....

Yes but it's no where near slow enough. In some galaxies you actually find it gets faster further out.
is there a way in your mind my theory DOES work?

No not really, the rotation curves can really only be explained by saying that the force of gravity pulling objects towards the center of the galaxy increases as you move away from the galactic core. But how on Earth is that possible when we clearly know that gravity gets weaker as you move away from the object causing the pull? The only realistic solution is some sort of dark matter halo. You have to imagine the halo as if it were like a planet. If you dig a huge hole in the Earth you will find that the force of gravity pulling you towards the center of the Earth is decreasing. As you move away from the galactic core you're moving further towards the edge of the halo, which is equivalent to climbing back out of the hole. As you move closer towards the surface of Earth the force of gravity increases. So as you move away from the galactic core the force between you and the galactic core decreases, but the force between you and the dark matter halo increases, those two forces tend to cancel each other out quite nicely and the result is a flat rotation curve.
the higher we fly the less pull we experience... i think if we went inside the earth... the pull would only get bigger.... more pressure there....

Yes the force pulling us towards Earth gets weaker as we move away, which is why we should expect the force pulling on objects in a galaxy to get weaker as you move away from the galactic core, but the observations tell us that's not the case, the force remains stable out to great distances.
However if you move into the Earth the force does get weaker for two reasons: firstly there is less mass between you and the center of the Earth, secondly the mass above you is actually pulling in the opposite way. Even if you reached the center of the Earth you would be pulled back towards the surface.
