Query: Quantum Mesh Dynamics (QMD)   A consistent quantum theory of gravity has remained elusive ever since the
emergence of General Relativity and Quantum Field Theory. Attempts to date have
not yielded a candidate that is either free from problematic theoretical
inconsistencies, falsifiable by experiment, or both. At the heart of all
approaches though the difficult question of what it means for spacetime itself
to be quantized, and how that can affect physics, has not been addressed. In
recent years a number of proposals have been made to address the quantum
structure of spacetime, and in particular how geometry and locality can emerge
as the Universe cools. Quantum Graphity is perhaps the best known of these, but
still does not connect the emerged quantized spacetime to dynamics or gravity.
In this paper we start from a quantized mesh as the pre-geometry of space time
and identify that informationally and in a very natural sense, the natural laws
of gravity and Newtonian dynamics emerge. The resultant equations of gravity
have a Yukawa term that operates at cosmic scale ($10^{18}$ meters), and we use
data from the Spitzer space telescope to investigate experimental agreement of
the galactic rotation curves with encouraging results. We conclude by
discussing how this pre-geometry could result in the classical covariant
constructs of General Relativity in the low energy continuum limit.
