  We study five-dimensional Kasner cosmologies in a time-dependent Calabi-Yau
compactification of M-theory undergoing a flop transition. The dynamics of the
additional states, which become massless at the transition point and give rise
to a scalar potential, are taken into account using a recently constructed
gauged supergravity action. Due to the dynamics of these states the moduli do
not show the usual run-away behavior but oscillate around the transition
region. Moreover, the solutions typically exhibit short periods of accelerated
expansion. We also analyze the interplay between the geometries of moduli space
and space-time.
