  A cosmology inspired structure for phase space is introduced, which leads to
finitization and lattice-like discretization of position and momentum
eigenvalues in a preferred, cosmic frame. Lorentz invariance is broken at very
high energies, at present inaccessible. The divergent perturbation terms in
quantum electrodynamics become finite and small; this could become a
requirement leading to model restrictions in other perturbative theories. So
the very success of the usual renormalization procedures is simply explained by
their finitization, and is viewed as indicating the reality of the lattice.
