 From this description [and from other hints Tom has dropped], I infer
 that he disagrees with the notion that gravitational and inertial masses 
 are equal.  I would also infer that the inertial mass is larger.  Hence, 
 in the Meta model, stellar masses which are derived from binary star orbits
 are underestimates of the inertial mass.  

 However, galactic rotation curves, derived from stellar velocity dispersion 
 measurements, are estimates of the inertial mass.  These rotation curves 
 measure the velocity of the stars as they respond to an external force, 
 namely the gravitational potential produced by the other stars.

 Thus, is this the explanation of dark matter in the Meta model?  Dark 
 matter is nothing more than the difference between the gravitational 
 and inertial masses of stars?

 It is still not clear how extra interior matter increases stability.  The 
 stability of a star depends upon its surface gravitational field.
