  The observable Universe is described by a collection of equal mass galaxies
linked into a common unit by their mutual gravitational interaction. The
partition function of this system is cast in terms of Ising model spin
variables and maps exactly onto a three-dimensional stochastic scalar classical
field theory. The full machinery of the renormalization group and critical
phenomena is brought to bear on this field theory allowing one to calculate the
galaxy-galaxy correlation function, whose critical exponent is predicted to be
between 1.530 to 1.862, compared to the phenomenological value of 1.6 to 1.8
