Photon trajectories in models of the Universe that have constant negative spatial curvature are exponientially unstable. We demonstrate that they can be stabilized by additional randomm fluctuations in the curvature. The mechanism is analogous to the one responsible for stabilizing the stochastic Kapitza pendulum, We discuss the consequences for the cosmic micorwave background fluctuations.
