Abstract
In the semiclassical limit, the two-dimensional space-time which emerges from string theory is a black hole similar to the Schwarzschild solution. However, we find that in the exact space-time, the singularity is replaced by a regular surface of time-reflection symmetry. The maximally extended space-time thus consists of an infinite sequence of asymptotically flat regions linked by wormholes, rather analogous to the Reissner-Nordström space-time except that there are no singularities in this case. We also calculate the mass and temperature associated with this space-time.
