NS-Capture Theory predicted the constant galactic rotation curve in 1974.

As described in the page on the supermassive black hole prediction, NS-Capture Theory leads to a possible model of a lawn sprinkler as an explanation that would allow 10 times as many neutron stars as regular stars to exist in the Milky Way Galaxy in order to avoid the Galaxy collapsing on itself as a result of the gravity from all the mass.

It turns out that the lawn sprinkler model predicts a galactic rotation curve that is consistent with the galactic rotation curves of spiral galaxies that are actually observed. As that article points out:

• “In the late 1960s and early 1970s, Vera Rubin, an astronomer at the Department of Terrestrial Magnetism at the Carnegie Institution of Washington, worked with a new sensitive spectrograph that could measure the velocity curve of edge-on spiral galaxies to a greater degree of accuracy than had ever before been achieved.
  Together with fellow staff-member Kent Ford, Rubin announced at a 1975 meeting of the American Astronomical Society the discovery that most stars in spiral galaxies orbit at roughly the same speed”

While I am not claiming that the lawn sprinkler model of the Galaxy is a necessary consequence of the NS-Capture Theory, the point is that NS-Capture has logical consequences that are far-reaching in terms of our understanding of many areas beyond its core claims, and that, in fact, since the original discovery of NS-Capture theory in 1974, there have been several discoveries made in other areas of astrophysics that are consistent with the types of observations that NS-Capture implies are likely to be found.

The basic claim of NS-Capture is that there must be around 10 times as many NS’s as regular stars in the MWG and this claim is supported as described in the diagrammatic proof. The predictions described here are conjectures based on the assumption of validity of NS-Capture.
