We review discoveries in the nonlinear dynamics of curved spacetime, largely made possible by
numerical solutions of Einstein’s equations. We discuss critical phenomena and self-similarity in
gravitational collapse, the behavior of spacetime curvature near singularities, the instability of black
strings in 5 spacetime dimensions, and the collision of four-dimensional black holes. We also discuss
the prospects for further discoveries in geometrodynamics via observation of gravitational waves.
