DESCRIPTION:In recent years there has been a resurgence of int
erest in quasi-cyclic cosmologies. With this is mi
nd\, consider the universe U as a deterministic dy
namical system and ask what is the geometry traced
out by trajectories of U in U's state space. WIth
positive cosmological constant and with Planck-s
cale information loss at black hole singularities\
, there are good grounds to postulate that\, asymp
totically\, this causal geometry is a measure-zero
fractal. With this as motivation\, a fractal I_U
is constructed from which the statistics of multi-
qubit quantum theory are emergent. I_U is a causal
but atemporal invariant set for the deterministic
dynamics of U and forms the basis for the develop
ment of a causal realistic geometric theory of qua
ntum physics where Bell's Theorem is nullified wit
hout conspiratorial fine tuning. The complex Hilbe
rt Space of standard quantum theory arises as the
singular limit of geometric properties of I_U. Inv
ariant set theory provides a potential explanation
for why zero point vacuum fluctuations do not con
tribute to the value of the cosmological constant\
, and\, above all\, suggests that attempts to quan
tise gravity (in the traditional field theoretic s
ense) are physically misguided. (Ref: Proc Roy Soc
