The rotation curves of spiral galaxies are not only flat
but still oscillating
Example - "Milky Way"!
Approximation of the mass density by oscillating function shows a minimum in
the solar neighborhood
We are in the almost empty space and so can the "Dark Matter" does not see. It is hidden far away from us - in the galactic arms!
This is reminiscent of the asteroid belt in the solar system or planetary rings around Saturn and Jupiter. Therefore the dark matter may be composed of rock (asteroids and planets) and water (comets).
