145 Chapter 7 Conclusions and Outlook Experiment drives physics. Our description of natural laws evolved not from aesthetics but falsifiable predictions compared to data. Scientific advance led us to the Standard Model of particle physics, with SU (3) the gauge group of the strong force coupling to fundamental quarks of fractional charge. Every tractable theory of nuclear physics points to a new paradigm at scales on the order of Λ$_{QCD}$, at which point quarks and gluons are presumably liberated from their hadronic prisons. It is clear that the prerequisite densities are reached at $_{Rhic}$, but many questions remain, theoretically and experimentally. If one were to sum up the discoveries at Rhic in two words they would be flow and jets. The low- p$_{T}$ azimuthal anisotropy appears to saturate the ideal hydrodynamics bound. High- p$_{T}$ jets are quenched, and, shockingly, heavy quarks are suppressed at a level similar to light quarks and gluons. Addi- tionally the intermediate- p$_{T}$ v$_{2}$ is surprisingly high for both light hadrons and nonphotonic electrons. Hydrodynamics results hold the tantalizing possibility for direct evidence
