ABSTRACT

Thirty years after the discovery of gamma-ray bursts (GRBs), we now know that at least the long-duration/soft-spectrum GRBs are the result of collapsing massive stars. I will review the most direct of this evidence and then talk about what this might mean for using GRBs to probe the early universe in new and exciting ways. Finally, I will review the multifaceted observing program that we are now building to pursue GRBs in this way.
