1. Globular clusters show a relationship between colour and radius. This is described in . The reason for this is not understood but may not be related to antigravity matter.
2. Several concerns are listed in the Analysis of Elliptical Galaxies.
3. From the approach velocity in Section 3.6 of the Antigravity Matter paper and from Equation 26) of the paper we conclude that antigravity matter should approach to within 2-3 AU of the Sun. This seem far too close.
4. Work continues to define the values of the parameters relating to antigravity matter.
