Superstring theory is a very exciting area of study because it has the serious potential to be the right theory for describing the fundamental nature of our universe.  All the elements are in there: quantum physics, bosons, fermions, gauge groups, and gravity.  In the last several years there has been great progress in understanding the overall structure of the theory including D-branes and string duality.  String theory has been applied with great success to the study of black hole physics and quantum gravity. However, there is much work yet to be done.
