  We discuss the low-curvature regime of time-dependent matrix theories
proposed to describe non-perturbative quantum gravity in asymptotically
plane-wave space-times. The emergence of near-classical space-time in this
limit turns out to be closely linked to the adiabaticity of the matrix theory
evolution. Supersymmetry restoration at low curvatures, which is crucial for
the usual space-time interpretation of matrix theories, becomes an obvious
feature of the adiabatic regime.
