-Now, the post shock density is comparable to the density of the infalling ambient. However, the velocity is very different, as it should be in retrospect. This leads to large deviations between the ram pressure of the infalling ambient and the ram pressure of the splashed material.
+Now, the post shock density is comparable to the density of the infalling ambient. However, the velocity is very different, as it should be in retrospect. This leads to large deviations between the ram pressure of the infalling ambient and the ram pressure of the splashed material. So large in fact (3 orders of magnitude), that the ram pressure of the splashed material doesn't make it on this plot; Pram = 1.5*10^-12^ for the post-shock flow. 
 
-The incoming flows have a high speed, and once shocked, though decreased, is still high. The ambient, however, is starting from rest. This means, that by the time the entire simulation has completed (i.e. long after the ring has formed), the ambient has still not acquired enough momentum to make the ram pressures balance.

-In hindsight, this was always going to be the case, as the ring is not present in the hydro case, and so the ambient's own dynamics are too weak to constrain outflowing material from the collision region.
