  This first of two papers is a speculation on the nature of Mach's Principle,
derived from the formulation of two questions: (A) Can a globally inertial
space and time be associated with a non-trivial global matter distribution? (B)
If so, what are the general properties of such a global distribution? The
answers are yes subject to the condition that mass is distributed fractally
with D=2. Such a prediction is supported, for example, in Joyce, Montuori,
Labini astro-ph/9901290.
  The second paper then shows how gravitational phenomena arise as consequences
of perturbations of this equilibrium D=2 distribution, and applies this theory
to spiral galaxy dynamics. Specifically, the second paper derives a
gravitational model for an idealized spiral, defined to have perfect
cylindrical symmetry. One of the main results of this analysis is that, *in the
disc*, V_rot = A/R^alpha where (A, alpha) are constants which vary between
spirals. See astro-ph/0107305, which concludes that a power-law model is
powerfully confirmed for ORCs as a statistical generality over large samples,
and astro-ph/0107300 for new phenomonology discovered via this analysis.
  Thus, unlike MOND, we have only been concerned with model predictions made
for idealized matter distributions, and tested over very large numbers of ORCs.
But, like those of MOND, the predictions are very powerfully supported on the
data. For this reason, we hypothesize that perspectives of MOND are buried
within our own formalism. This remains a topic for future work.
