  We study quantum corrections to the classical Bianchi I and Bianchi IX
universes. The modified dynamics is well-motivated from the asymptotic safety
program where the short-distance behavior of gravity is governed by a
non-trivial renormalization group fixed point. The correction terms induce a
phase transition in the dynamics of the model, changing the classical, chaotic
Kasner oscillations into a uniform approach to a point singularity. The
resulting implications for the microscopic structure of spacetime are
discussed.
