By colliding heavy ions at high energy, it is hoped that novel forms of matter are created, where the normal QCD structure of the vacuum is melted and quarks and gluons represent the degrees of freedom. Unfortunately, measurements of the collisions are confined to the momenta of the thousands of particles comprising the collision debris. In this talk, I will show how we are now able to infer space-time information about the collision from correlations observed among the outgoing particles, and present a brief history of Hanbury-Brown Twiss interferometry.
