Abstract

It is shown that a large class of time-dependent solutions to Einstein's equation are classical solutions to string theory. These include metrics with large curvature and some with spacetime singularities. Unlike the case of orbifold singularities, it is shown that string propagation through the singluar region is not well behaved.
