  The quaternionic Hopf surface, HL, is associated with a non-compact moduli
space, ML, of stable holomorphic SL(2,C) bundles. ML is open in MLc, the
corresponding compact moduli space of holomorphic SL(2,C) bundles, and
naturally fibers over an open set of the quaternionic projective line HP^1. We
pull back to ML natural locally conformal kaehler and hyperkaehler structures
from MLc, and lift natural sub-pseudoriemannian and optical structures from
HP^1. Unexpectedly, the holomorphic maps connecting these structures solve the
the classical Dirac-Higgs equations of the unbroken Standard Model. These
equations include: all observed fermionic and bosonic fields of all three
generations with the correct color, weak isospin, and hypercharge values; a
Higgs field coupling left and right fermion fields; and a pp-wave gravitational
metric. We hypothesize that physics is essentially the geometry of ML, both
algebraic (quantum) and differential (classical). We further show that the
Yang-Mills equations with fermionic currents also naturally emerge, along with
an induced action on the ML structure sheaf equivalent to the time-evolution
operator of the associated quantum field theory.
