  We study the effects of an information-theoretically motivated nonlinear
correction to the Wheeler-deWitt equation in the minisuperspace scheme for
flat, $k=0$, Friedmann-Robertson-Walker (FRW) universes. When the only matter
is a cosmological constant, the nonlinearity can provide a barrier that screens
the original Big Bang, leading to the quantum creation of a universe through
tunneling just as in the $k=1$ case. When the matter is instead a free massless
scalar field, the nonlinearity can again prevent a contracting classical
universe from reaching zero size by creating a bounce. Our studies here are
self-consistent to leading order in perturbation theory for the nonlinear
effects.
