Hi, I'm reading up on CDM and related theories on Wikipedia and came across the "Cuspy Halo Problem". I followed the link, but it did not provide any further insight to help me visualize this phenomenon (or the absence of it[?]). Please help explain the "Cuspy Halo Problem" to a newcomer. My current guess is that the problem is that CDM seems to predict a very dense, "deep", and pointed middle section (like a top) upon which the rest of the Universe is rotating, but that this prediction has not played out in observations (and may in fact have been contradicted). Is that correct? Thanks as always!
