DESCRIPTION:In recent years there has been a resurgence of interest in qua
 si-cyclic cosmologies. With this is mind\, consider the universe U as a de
 terministic dynamical system and ask what is the geometry traced out by tr
 ajectories of U in U's state space. WIth positive cosmological constant  a
 nd with Planck-scale information loss at black hole singularities\, there 
 are good grounds to postulate that\, asymptotically\, this causal geometry
  is a measure-zero fractal. With this as motivation\, a fractal I_U is con
 structed from which the statistics of multi-qubit quantum theory are emerg
 ent. I_U is a causal but atemporal invariant set for the deterministic dyn
 amics of U and forms the basis for the development of a causal realistic g
 eometric theory of quantum physics where Bell's Theorem is nullified witho
 ut conspiratorial fine tuning. The complex Hilbert Space of standard quant
 um theory arises as the singular limit of geometric properties of I_U. Inv
 ariant set theory provides a potential explanation for why zero point vacu
 um fluctuations do not contribute to the value of the cosmological constan
 t\, and\, above all\, suggests that attempts to quantise gravity (in the t
 raditional field theoretic sense) are physically misguided. (Ref: Proc Roy
