We view planets moveing in the solar system according to
Keplerian/Newtonian Mechanics; based on this, the average orbital speed
of an object at a specified distance away from the majority of mass (sun
in the solar system) would decrease inversely with the square root of
the radius of the orbit.

    This view is based on what we see from the order of magnitude our
solar system, where each element (planets) are left to obit the central
mass (sun) with limited interplay from the other planets; but when
compared to the order of magnitude of the universe, the fabric of the
body of the universe is more like a weave, an interplay of the elements
that create synergisms, that weld the body's elements together and move
more as a unit.

    We currently use a model that puts the majority of mass in a halo
(Cold Dark Matter CDM), a mysterious out-layer of mass that controls the
internal movement of galaxies; but are we failing to visualize a synergy
of gravity at the galactic level, a glue of sorts, a unifying effect
that creates a movement that coordinates the totality.

  Assuming the existence of Dark Matter, and there is increasing
  evidence these days, Even Newton's laws do well at predicting
  galactic rotation curves.
