The leading-order late-time asymptotic for linear waves on radially symmetric stationary perturbations of (2+1)-Minkowski space is proportional to u^{-1/2}v^{-1/2}.
Four new exact Bianchi I solutions in a non-variational scalar field model produce Big Bang, Big Crunch, Big Rip, and cyclic behaviors, with stability to inhomogeneous perturbations depending on singularity type.
