I believe that in order for galaxies to maintain their general disc shape over billions of years, steller DM gravity has to be directional. It shows that DM gravity of a star is much higher in the ecliptic, surely? Do any computer galaxy modellers agree that this might be possible?

The disk shape is due to centrifugal force.Why wouldn't the stars slowly spread higher or lower from the galactic plain then? Centrifugal force can't explain this.
I'm sure that Chaos Theory would predict a wandering of the stars above and below the galactic plane much more than is observed with the standard theory of gravity.
Show me your maths proof then
