The current status of the understanding of jet quenching in nuclear collisions at RHIC is reviewed. The experimentally large level of suppression of jets in Au+Au collisions at RHIC is a success, but also introduces a challenge in terms of quantitative understanding of the properties of the collision zone. The medium appears to be equally black to all interacting probes utilized to date, limiting the amount of tomographic information that can be obtained from quenching phenomena. In order to recover this information, a probe to which the medium is gray needs to be found.
