And the answer is simply that they are ill informed about r^2 being the best fit to all the data, popular talks just use rotation curves as a simple to explain justification and don’t bother with structure formation arguments and the like.
- mikorym 8y agoOP here, "why on earth" was in context to the talk. At said talk the person assumed the audience generally want r^2 to hold, but did not mention that r^2 should preferably hold (for the reasons posted in other comments). In fact, the scope of the talk was much different. It mainly was to explain how we are looking for dark matter. Of course, this slightly diffirent topic is still very interesting. It happens to be confusing, though, for a person that may prefer theory extension over empirical extension (in their own research).
